History
• A 54 yr old woman has a head & chest injury
from an automobile accident. She is
confused and complains of dizziness, partial
blindness & headache.
• At ED registration she is entered into the
Hospital Information System (HIS) and
assigned a medical record number.
• ED takes her vital signs and sends her to
Radiology.
History
• First she goes to x-ray, where she has a
chest x-ray, (2 4096x4096 images)
X-ray
ADC Compact Digitizer
• Small footprint
• Cassette buffers: 10 in, 10
out

ID software
• Records patient and exam data
(“menu”) onto cassette memory
• Menu drives subsequent
autoprocessing of image
• Runs on PC or Sun
• Customizable data fields
• ID and Preview software can run in
synergy on same PC or Sun
Connecting software
• Rislink Toolkit: demographic data input
from RIS systems
• Autorouting software: linking
destinations to exam menus
• Softcopy Toolkit: image output to nonDICOM PACS systems
• DICOM store connection
Quality monitoring tools
• Test phantom set: geometrical and
contrast test objects
• Auto QC Software: automatic
measuring and report generating from
test phantom exposures
Diagnostic applications
• All plain x-ray exams:
thorax bucky/bedside, skeleton,
abdomen, contrast, uro/tomo, pediatric,
etc...
• Special exams:
dental panoramic, full leg/full spine
• Not yet supported:
mammography
CT scan
• Then she goes to CT, where she gets a
head scan (20x2 512x512 images)
• and a chest scan (40x2 512x512
images).
CT Chest
History
• The x-ray and CT are normal.
• How much data has she accumulated
so far and how many people have
looked at her studies?
US- Blood flow
• Now to ultrasound where she has a
carotid Doppler study performed
(4 64x64 color images).
US
Doppler US
MRI
• And then an MRI of her head ( 8 x 20
256x256 images)
MRI
History
• By now she is asleep. Her last report
shows a history of stroke so although
the MRI is negative the neurologists
want to start TPA therapy…
• At this point she regains consciousness
and it is revealed that she has been
misidentified. What went wrong?
What does the system look like?
• HIS
Communicate by HL7
• RIS
Communicate by DICOM
• PACS
