HP Workstations in an era of open systems 
Scottsdale Medical Imaging is a radiology practice
with 10 clinics scattered throughout Phoenix’s East
Valley area. The Scottsdale clinics use a Picture
Archiving and Communications System (PACS) from
GE Healthcare. The PACS provides for the massive
amount of data generated by Scottsdale’s diagnostic
image studies, and enables radiologists anywhere on
the company’s network to call up studies for review
and evaluation using high-resolution diagnostic
Workstations. 
“It’s no accident that we rely on HP products
throughout our enterprise. Each time we evaluate
competitive products; we return to HP and have a
good experience. Our faith in HP products has been
justified again and again. And HP backs up good
hardware with good service.” 
Andrew Willy, Information Systems Supervisor, Scottsdale
Medical Imaging, Scottsdale, Ariz.
GE Healthcare has since standardized on HP
Workstations for its PACS.
Because of the reliability and manageability of the
desktop PCs, storage and servers, the Scottsdale
Medical Imaging has been a long-time HP customer. In
part, Willy says, there was a predisposition toward HP
because the company had a history of good
experience with HP products and personnel. HP
hardware was familiar, and Willy’s staff had
supported it effectively as the practice grew.
“We rely on HP systems to support the core mission of
our business. Month in and month out, they deliver the
performance and reliability we need.”

But the most importation consideration was
performance. “We needed Workstations that were
designed with performance as a driving goal,” says
Willy. “The imaging applications that radiologists use
can be memory and processor intensive, so they
perform dramatically better on a Workstation-class
machine. And I personally believe that HP
Workstations deliver great performance. ” HP
Workstations allow for fewer failures and less
downtime, which expedites diagnoses, a primary
objective of patient care. 
“We look at thousands of images at our practice, 
and a single exam can involve many images,” Willy
explains. “The HP Workstation within the PACS
needed to display those exams in a manner that’s
quick and convenient and makes the radiologist as
efficient as possible.”
The HP xw6400 Workstations at Scottsdale Medical
Imaging are configured with 3 GHz Intel® Xeon®
5160

dual-core processors,

a Barco Coronis 3
megapixel graphics card supporting twin monitors with
1536 x 2038 resolution, 80 gigabyte SATA disk drives
configured for RAID, and 2 gigabytes of RAM. Willy
says the HP xw6400 Workstations provide a
significant improvement over the older hardware they
replaced. 
Another important issue for Willy was reliability and
the availability of the data. “Our radiologist
Workstations have to be supremely reliable. We can’t
have a radiologist’s work interrupted by a hardware
failure, so we view the HP Workstations like servers.
We expect them to be available almost 24/7.”
“Hard drives are a common failure point in all
systems, and we felt it was valuable to have our
Workstations be deployed with drive redundancy,”
says Willy.
In addition, he says, the HP Workstations allow
radiologists to multitask more efficiently, moving
between image interpretation and other tasks quickly. 
Advanced desktops for demanding environments
“HP Business Desktop PCs are in every part of our
organization, from the financial and billing operations
to our general office and clinical operations,” says
Willy. “The 7000 series PCs deliver maximum stability
and manageability for Scottsdale’s business and
clinical needs.”
