📚 The Role of DICOM in Image Management
This paragraph delves into the specifics of how DICOM facilitates the management of medical images. It explains that DICOM is a universal format that allows for the standardization of image storage, retrieval, display, transmission, and printing. The paragraph follows the process of how ultrasound and X-ray images are captured and stored in DICOM format, independent of the manufacturer. It also discusses the use of Picture Archiving and Communication Systems (PACS) for image storage and retrieval, and how radiologists like Dr. Nugget can use DICOM viewers to interpret these images. The paragraph concludes with the creation of a final report by the radiologist and the various options for sharing the images with patients, such as printing or burning them onto a CD.
🔍 Recap and Future Insights on Healthcare IT
The final paragraph serves as a recap of the video's content, summarizing the key points about DICOM's role in the workflow of medical imaging. It highlights the universality of DICOM in storing, transmitting, viewing, and printing images across different modalities and vendors. The paragraph also teases upcoming content that will explore imaging and healthcare IT in more depth, including discussions on PACS, radiology, HL7, and specific DICOM operations. It invites viewers to stay tuned for more educational videos on healthcare IT for beginners and advanced topics, promising a comprehensive course outline on the channel.

what is dicom
let's take a moment to understand the
imaging standard used in healthcare
the dicom standard
[Music]
meet dr nugget dr nugget works at
bearcat mountain hospital wait what
dr nugget is a radiologist his job
is to interpret medical images for his
patients
[Music]
he will need to view a variety of images
such as x-rays
cat scans and mris
[Music]
now let's take a closer look at how this
can be accomplished
using dicom
let's do this by watching dr nugget as
he goes through a day in his life
well after coffee of course
dr nugget checks the electronic medical
record system
for now let's just think of the emr as a
way to track and record patient data
[Music]
dr nugget receives two orders for a
patient
one order is an x-ray of the chest the
other order
is an ultrasound of the heart
the radiology system within the emr
indicates that the patient
is actually scheduled for today
[Music]
when the patient arrives he'll be able
to check in at the front desk
once checked in by the front desk the
radiology information system is now
updated with the new status of the
patient
this informs the clinical staff that the
patient is ready to undergo his
procedures
[Music]
the chest x-ray
the patient undergoes the chest x-ray
this diagnostic procedure shoots
radioactive light
through the body to acquire data
this radioactive form of light is called
an x-ray
as the x-rays pass through the body
static grayscale images are acquired
these images are typically
two-dimensional and high resolution
the x-ray technologist will now check
that he's acquired all the required
images
and ensure the quality of each image
before he sends our patient off to the
next procedure
now our patient is ready for his next
procedure
the sonogram also known as the
ultrasound
[Music]
the patient undergoes the ultrasound
procedure this diagnostic procedure uses
sound to acquire data
sound waves bounce off the patient's
organs to acquire images
these images can be viewed in color
still image or movie format
alright what a long day so it looks like
our patient's done
and now both the x-ray and the
ultrasounds are ready to be sent to dr
nugget
hmm but can that be done both these
images are so different
okay quick recap here we've got two
types of images
first we've got x-rays then we've got
ultrasounds
as we stated before the x-rays are
generated by using radioactive
light to acquire these images
[Music]
and the images themselves are typically
monochromatic two-dimensional images
so in contrast the ultrasound uses
sound instead of light to acquire the
images
instead of your black and white images
with ultrasounds
we can see that we have videos and
images in color
to add more variety to the mix these
devices could be manufactured by
different vendors
regardless dr nugget needs to view both
image types
on one computer ultimately
these images need to function in a
universal format
that's where daikon comes in dicom
stands for
digital imaging and communications and
medicine
dicom is a standard that defines how to
query retrieve
display
store transmit
[Music]
and print images
[Music]
uh can we get back to the story
[Music]
so how does dicom help us
well when the ultrasound images are
captured and generated
they're stored in dicom format
[Music]
when the x-ray images are captured then
generated
they too are stored in dicom format
dicom store ensures all images are
stored in a standard format
regardless of who the manufacturer is
[Music]
because we're using a universal standard
to store the images
we can also transfer the images using
the same standard
[Music]
the images can be transferred to a
picture archive and communication system
otherwise known as pax
from this pack storage dr nugget can
access these images onto his computer
[Music]
if he wants you can even view these
images side by side
[Music]
by utilizing a pax viewer or a daikon
viewer
dr nugget will carefully interpret these
images
[Music]
at this point the images look normal so
dr nugget creates a final report for his
patients
by utilizing the dicom print function dr
nugget can print a copy of the images
you can also burn the images onto a cd
finally to complete the workflow our
radiologist can discuss his findings
with this patient
[Music]
we've gone through an entire workflow to
see how diacom is
integral in every step of the way good
job doc
now only 230 scans left to read
wow we've learned a lot here we talked
about workflows
orders modalities emrs and packs
so let's just do a quick recap
in our story dicom allowed us to store
transmit view and print images using a
universal standard
we talked about dicom store without
modalities stored the images to the pax
archive
we talked about daikon viewing when dr
nugget uses pax viewer to look at the
images
finally we talked about daikon print
when dr nugget printed out his x-ray to
review with his patients
[Music]
so as you can see thanks to the
universal dicom standard
we can perform these functions
regardless of the modality or the vendor
please like and subscribe to this
channel to learn more
in the upcoming videos we'll talk about
imaging and healthcare i.t as a whole
we'll talk about pax radiology bnas and
hl7
[Music]
we'll also do a deep dive into dicom
we'll talk about specific
operations such as query retrieve see
fine c moves and web services
[Music]
we'll also learn about the clinical
aspect of each modality
for example we'll talk about nuclear
medicine radiation physics and the
effects of ionizing radiation
we'll discuss other methods of imaging
including magnetic resonance imaging
ultrasound and photographic images taken
from a regular camera
for our planned releases you can expect
to see more videos about healthcare it
for beginners
but as we create more content we'll dig
into the more advanced topics
whether you're interested in learning
how to advance your career in the
industry or if you're looking to break
into the field
stay tuned for a course outline on this
channel
[Music]
