A Mayo Clinic podcast for laboratory professionals, physicians, and students, hosted by Justin Kreuter, M.D., assistant professor of laboratory medicine and pathology at Mayo Clinic, featuring educational topics and insightful takeaways to apply in your practice.
This is Lab Medicine
Rounds, a curated podcast
for physicians, laboratory
professionals, and students.
I'm your host, Justin Krueter,
the Bow Tie Bandit of Blood,
a Transfusion Medicine
pathologist at Mayo Clinic.
Today we are rounding with Shane Ferraro,
a Pathologists' Assistant,
Assistant Supervisor
in the Division of Anatomic Pathology
at Mayo Clinic in Rochester, Minnesota,
to talk about the important
innovation of 3D scanning.
Thanks for joining us today, Shane.
Yeah, my pleasure.
Thanks for having me.
Very exciting.
Yeah. So 3D scanning is
something that I think a lot
of us are starting to kind of hear about.
Some of us are probably
getting a chance to see
about this innovation.
I'm curious, from your perspective
why is 3D scanning an an
important innovation in pathology?
Yeah, it's a, it's a
very exciting question
and a very exciting topic.
So from all of my experiences
with our 3D scanning system so far
I think the most important
impact is on education.
And for instance, so
with our pathologist assistant team,
we're heavily invested in
resident and PA student education.
So the applications of this
technology really allow
for like a versatile and
kind of conducive approach
to how people in anatomic pathology learn.
So we're very visual learners,
we're very hands-on, and
that's an extension
from our experience in like cadaver labs.
And, you know,
as we were to the frozen section lab here,
surgical pathology labs in general.
So the the applications
of the technologies here,
can really be fostered in a way to,
create environments that
are more conducive to learning.
So for instance, with this
technology, we can create things
like QR codes, which you
can bring to a presentation
and you can have the audience kind of scan
that with your phone,
and then they could look
at a 3D model that you
created on their phone.
So they get a really interactive
experience with that.
In addition to that
we also have the ability to
create actual tangible 3D models
from the specimens that we have scanned.
So when we do that
we can actually have those models shared
in an environment that's, that's not a
an actual like pathology lab.
So you don't have to worry
about safety precautions.
You don't have to worry
about balancing clinical
care with resident education.
So you can really hone in
on some of those skills
and really foster a good
environment for them to learn
in. So, very exciting
from that angle for us.
Yeah, I mean, it sounds really
almost transformative, right?
I think you mentioned a couple
of things that you can do
that we haven't really
been able to do before.
You mentioned, so with a 3D scan
that we're able to really
take anatomic models
and we can kind of,
the audience can play
with them on their phone.
And I'm curious, like when
you talk about, you know
educational change that's happening
because you can get the audience do that
are there certain
activities that you can do
with the audience that you
weren't able to do before?
Are there certain insights
that you're hearing
from the learners when you're
doing that kind of approach?
It's hard to really know
because this is
something that we just received
and as I mentioned, like, so all
all of our PA educators
are, are really excited.
I've had several of them already asking
about the opportunities to
actually get their own specimens
and their QR codes to share.
So the enthusiasm is there.
I can't quite comment
on how it might transfer
into an audience kind of
engagement, but just the fact
that somebody could get
their phone, scan the QR code
and then just you can
hear all the audible ooh's
and ah's as they go through a specimen.
It sounds like a very exciting thing.
And I look forward
to having those opportunities with people.
So
Yeah. Absolutely.
So what do you think is important
for our audience to
understand about 3D scanning?
So two, two things come to mind.
You know, we talk
about 3D scanning as if
it's like some kind of
really like futuristic abstract technology
when in reality it's,
it's more simple than that.
So the machine is, you know,
it's this big cube and
we would put the specimen
inside this chamber
and it would have,
it's mounted on a rotating platform
and we could kind of choose
like what kind of, you know
mount it's on, it could be
a glass surface, it could be
like a pin mounted method,
or we can do like,
it's a resting kind
of mesh kind of screen.
So it's on this, this, this mount
and then it's in the chamber
and there's several cameras
kind of lined along the edge.
So the specimen will rotate
and the cameras are just
taking multiple photos
of it as it rotates.
So it's just a really
fancy kind of camera setup.
So those photos actually act as the
the data for the 3D model to be rendered.
And these models are
really like crisp and clean
and this is like, it's
very simple and very scalable.
So it's something
that I think will be much
more prevalent going forward.
The other
the other thing that I
think is really interesting
about this is, I talk about
the education side a lot
and that actually transfers
over towards patients too.
So for instance, here
with our PA service and
our pathology service,
we see a lot of heart
and lung transplants.
So we actually have a
service where patients
can request this upfront.
They can,
they can request to see
a scan of their specimen.
So the, the patient could come
in after they've had
their lungs, you know, removed.
They have a new set of lungs
they can come in with
their family and they could,
they can talk to the
actual pathologist who
reviewed the actual specimen,
the, the patient's lungs.
They took sections to
look at microscopically
and they could get a one-on-one
interactive session to
kind of go over the specimen
and kind of really see
the cycle of care.
And then they can also go
home with that specimen
so they can have a, a memento
and a reminder of the service
and the care that they
experience here at the clinic.
So there's some
really cool things, you know
that are happening in addition to like
just the education that
goes along with this.
So
You know, another thing that
comes up in my mind is, I
I mean, you're a pathologist
assistant, you know
are you taking this
home to show your family
members what kind of stuff you deal with?
I'm excited to,
I have to be careful.
I mean, I could tell my wife
about some of these things
but she doesn't wanna hear it as much.
So I gotta, I have to
make sure I pick the right
kind of specimen to bring
home that might not
hit those kinds
of buttons for some people.
Oh, I,
I understand that. That
kind of gets us into, you know
what are some of the practicalities
for implementing 3D scanning
and a pathology practice?
Right. You mentioned that
you're seeing this as really a
a very scalable technology.
Yes. So going back to kind of how
I mentioned how
it's, yeah, it is scalable
and it's a really
simplified kind of setup.
So right now we're
launching this system
in our frozen section lab
which is a rapid
intraoperative diagnosis lab.
So it's a very clinical heavy setting.
We, provide intraoperative
results to surgeons
so that they can know how to
advance with their procedures.
So balancing that kind of aspect
of our work with getting some
of these educational
requests, is a hurdle.
You know, so as we kind
of learn how to, how to
balance our work and really
accommodate these requests
because for the most part
this is primarily an
educational kind of setup.
There are, you know, ideas
to kind of expand this
into a more clinical kind of
aspect, but right now it's
it's really finding that, that
that sweet spot to get the
get our pathologist and the
surgeons the answers they need
and really make sure that we
can streamline our processes.
And, you know, that, that
might be something as simple as,
as I mentioned earlier
there's different mounting techniques.
So for instance
if you have something that
might be more soft, like a
like a fatty kind of tumor
that's really squishy
and just kind of sits, you're
you're not going to be able
to put that on like a
a pin mounted method.
You're going to have to put
it on the glass surface.
If you have something like a
bone, which might look weird
or it might stand at an awkward angle
using that glass might not work.
So kind of making sure
that we can rapidly kind
of put together the mounting
technique, get a good scan,
get the surgeon what they need,
get the consultant what they need,
and make sure all kind
of parties are involved,
is probably the biggest
hurdle in, in my mind.
And are there different teams
that you are interacting with
like outside of pathology
that is helping to kind
of bridge to make some bridges
between pathology and
other clinical departments?
So, right, so the system that we use
the actual scanning system
is called Med Creator.
We're supported by a thing,
which is the company named
they're based out of Chicago
and they have other
departments here that they
they collaborate with.
So we haven't really worked too much
outside of our department.
We work closely with the
autopsy lab who really
pioneered a lot of this, these techniques
and kind of helping support
this growth of the technology.
So we work closely with them
but otherwise outside of
like surgical pathology and
you know, anatomic pathology
we haven't worked with too
many other departments.
I'm excited for those opportunities.
I know in the past
as this kind of technology
was more experimental
there were different
opportunities we had with
I think it was radiology
who did want to like
coordinate with certain specimens.
So we did have those
opportunities in the past
which was a lot of fun.
I had a lot of fun with that.
So
Yeah. And you mentioned,
you know, in pathology
it sounds like it kind of
got its route started
with forensic pathologists
and then you're saying now
it's kind of being brought
out to the surgical practice?
Yeah, so our, our autopsy
lab, it, it functions as a
a medical or an in-house
autopsy lab
in addition to the, the
forensics pathology service.
So those, it was more
or less those medical,
those kinds of autopsies, those
educationally approved
for cases where we were kind of expanding
on some of this technology.
Their interfaces
are a little bit more complex
and as I mentioned before
thing has been able to really condense
and simplify all the
applications and, you know
for instance, the software
that controls how the
the mounting station
kind of rotates, stops
the cameras engage, all
of all that stuff was kind
of worked together in autopsy
and they really like
consolidated those applications.
Hmm. And, and how long does
it take to scan some tissue?
Is this something
that is relatively quick
or is this like a day long process?
It's actually, yeah, I
didn't even think about how
I'm commenting on how interesting this is.
So it's really simple.
It's really quick actually.
So we would just need
to go into the software
the software that they've
made, this kiosk application
we would just need to basically adjust the
the camera settings and you could adjust
like the model quality,
but it's not necessary.
So you would just put in
your settings, name your file
hit the button, and it
takes about five minutes
for these pictures to be taken.
So once the pictures are taken,
you can open up the chamber
and retrieve your specimen.
And then the, the actual
rendering of the model
will take 20 minutes.
So you can, you can have a
really quick turnaround, but
in the grand scheme of things,
those five minutes are really
important for a patient who's
on the operating table.
So you have to still
balance making, you know
making sure you're
getting those results back
to your surgeon and the consultant.
But it, it is very quick,
relatively speaking, so
Oh wow.
It's interesting.
Yeah. You know, so quick to scan.
And then also it sounds like
if everybody's able to get
on their cell phone and
manipulate it, it's not like
the old kinda lag time of, you know
you have to make sure
you're on good internet.
Correct. And yeah, so we can look
at the model real time on the system.
Once it's, we can
we can look at it on our
screen as, as it's rendered
and we can kind of look at
it and say, you know what
maybe maybe we should try
to get a better angle or, no
this is great.
You know, we can
we can know real time if
what we have is good.
Is the thought is this going to replace?
I know there's always been
kind of surgical photography
or surgical pathology photography.
Is, is this thought to replace this
in the next five, 10 years?
In my mind, no.
I don't.
I think that there's too much
value in photography itself.
3D models have their place
and you know, they really
they really can fit into the picture.
Sorry for the pun,
but I don't think that
photography is gonna go away.
There's just you, there's too
much pop, there's too much pop
to photographs that you
kind of lose in a 3D model.
And I, I enjoy taking
photos of our specimens
and I take a lot of pride in it
so I don't want to see that
go away anytime soon.
Yeah, no, I, I really appreciate
your kind of nuance too.
You know, it's not
like the panacea that's
gonna replace everything.
There's a time and a place
these certain things.
So I guess that kind of brings me
to my final question of
where do you see, you know
this innovation going over
these next five, 10 years?
Yeah, it's, it's fun.
It's really fun to think about that.
And it's, I get a lot
of like insights from
our PA team and
they have some plans,
they have some concepts.
One of the really interesting things is
as I mentioned before, you know, we could
you can print 3D models, but what you
you can also do is you could change colors
of certain anatomic sites or
structures on these models.
So we can create like unique
really unique models to
show the relationships
of adjacent structures.
And that's, that's a significant
it's a really important skill to have
in anatomic pathology and gross anatomy.
So we can do that.
And I think another kind
of step I would like to see
which really kind of
takes that to like the enth
degree would potentially
be the applications
for augmented or virtual reality options.
So what I'm thinking is, like,
you could take a specimen,
so you could take a kidney specimen,
so you could take an
overall scan of the specimen,
and then you could do
like a step-by-step scan
as you would grossly examine the specimen
and grossly examine like
if there's a tumor present,
how it relates to adjacent structures.
And you can provide a
step-by-step gross examination
of that for a learner.
And they could have, they could pop
on a VR set and kind of go
through the whole, you know
the whole steps and the
the maneuvers of grossing in
a, like a surgical specimen.
Or they can have some kind of a
some other kind of like
goggle system that provides
like an augmented reality
system so that they can see
out of their periphery of
the side of their vision
like the actual step-by-step process of it
while they're going through
an actual surgical specimen.
It's, it's a lot of fun to
kind of think of these things.
I have no idea if they're 100% applicable
but it's a lot of fun to
kind of get these ideas
and see if they're, they're possible.
Yeah, I'm really excited by that.
I think something that
young learners in the field
of pathology struggle
with is sometimes looking
at something that's 2D and
having to kind of construct this
as a 3D and it, it sounds
like there's some wonderful
that may not always be
the case going forward.
Yeah, it's, I get, I'm excited.
I think this provides
a unique opportunity
for people to learn because maybe
maybe they're really
intimidated by an actual
like specimen when they first see it
so can provide a more
controlled environment
for them to get that hands-on experience
and the visual kind of
correlation between what they read
in the book, versus what it actually is.
So, very cool opportunities.
