Kj case studies to rk ending point
1.
2. Ron,
Attached are the descriptions of three case studies.
Would you like to review the outcomes?
#1. To improve upon the design of a CT suite
recommended by a vendor.
#2. To expedite the installation of a radiographic room for
use by the Emergency Department.
#3. To refine the design of filmless reading rooms for the
transition from film-based reading rooms to digital reading
stations.

Key Takeaway
Be extremely cautious of
installation advice provided
by vendors.
5. Example #2. Actual Case Study
Expedite installation of an emergency radiographic room
Room dimensions:
20’ x 24’
Starting Point:
• Current room to be taken out of service within 30 days
• Am not to look at anything else whatsoever for following reasons:
1. Any other changes would jeopardize getting this room installed
quickly.
2. There are – and will NOT be - any funds approved for doing
anything else for at least one year if not more.

6. Key Takeaway
Always identify an existing
site to use as a benchmark
for your design early in
your planning process.
Typical radiographic equipment
• Chest board for chest x-rays on back wall
• Radiographic table on which some patients lay
• X-ray tube hangs from ceiling mounting so it can move
about the room to aim in any direction
• Casework for supplies
Source: Google: Radiographic room design. Then select: “Images for radiographic room design”,
7. Assignment
Seen below is a layout for a radiographic room that pops up if you go to the Google site
listed below*. Using this layout or other information from this web site, create a layout on
the attached slide which is to be turned in at the start of class on Tuesday.
Key Takeaway
Be extremely cautious of
advice from Internet.
Watch for red flags.

room design. Then select: “Images for radiographic room design”, “Images for . . .”

Key Takeaway
Create a “Functional
ED
Drawing” for conducting a

current state assessment
Supplies
1
to understand existing
conditions as starting point.
Existing Conditions
Emergency 1. Current ED Radiographic Room to be taken out of service ASAP.
2. CT for Emergency use is in NE corner of Radiology Department
Department 3. Single slice CT is obsolete, not used for Emergency work. CT to be replaced in future.

4. Second MRI needed. Plans being developed to install in vacant interventional room.
11. New corridor
Outcomes:
1.Expanded space allocated from renovation from Angio Supply Room only to that seen above
2.Gained approval to install new CT within this space..
11
14. Conditions of Engagement:
1. “To look only at design of new filmless radiology
reading rooms (PACS) and nothing else.”
2. “Do not expect to make any changes as project
is over budget and behind schedule.”
3. “CT suite is absolutely off limits. It is done.”

What, if any, changes would you propose for this space?

19. Workflow Analysis Techniques
Create drawing to illustrate workflow at 15,000’
Case Study: Dartmouth-Hitchcock Medical Center
“No changes to be made to basic design, but was given
approval to suggest refinements.”
22. Workflow Analysis Techniques
Zoom in until at “ground level.”
Yellow shaded
area represents Note challenge in
operator’s line of getting patient
vision when into room,
looking at particularly if IV
console. To see pole, etc.
patient, operator
looks to left.
26. Net Result of Intervention and
Use of Tools
• One CT was moved to ED.
• CT Suite was redesigned to improve
workflow.
• Designs of PACS reading rooms were
significantly improved.

Editor's Notes
Among major flaws within this room are: Control booth too narrow as shown, let alone no raceway behind console. Virtually impossible to bring patient into room on stretcher. Boxes within room are for electronics. No allowance for any casework for supplies nor sink within room.
Design is almost perfect. Illustrates almost all mistakes one can make. This example from the internet illustrates many red flags Not only is toilet not needed for a radiographic room, but internal entrance only should be avoided as a general rule. Preparation rooms are not used for radiographic rooms. No external access to control booth for staff. Two major red flags
