Refurbishing CT Scanners
Professionally refurbished CTs look and perform similarly to brand new and used medical equipment. They offer medical and
imaging centers, looking to make medical equipment sales, affordable solutions
and outstanding value.
The performance, reliability and lifespan of a refurbished CT scanner depends
on the condition of the scanner prior to refurbishing; the quality of
replacement parts; the expertise of the technicians who work on it; and,
finally, the thoroughness of the pre-sale testing process.
High quality scanners manufactured by leading companies, such as GE, Philips,
Siemens, Picker, Toshiba and Elscint are refurbished most often. When a used CT
scanner is sold or accepted as a trade-in, the equipment as well as its
maintenance records are carefully scrutinized and assessed. A plan is developed
to refurbish in accordance with OEM specifications for the specific device and
all considerations are carefully recorded in a project database.
A dedicated project management team is essential for expertly and
successfully refurbishing complex CT scanners. The team coordinates engineers
during the de-installation and installation processes; crates and ships the
device; oversees all testing, refurbishing and documentation processes; and
integrates the scanner in its new setting.
Once a CT scanner has been de-installed and shipped to the center where it is to be refurbished, it is staged to allow testing at full power. Unit performance is assessed by running a variety of scans. Brushes and slip rings are serviced or replaced, as are displays, filters and other components.

The scanner is evaluated for detector gain, linearity and crosstalk and
adjusted as needed. Software is updated and verified. The system is calibrated
and undergoes quality assurance procedures, including assessing images generated
by the scanner. All activity is recorded in maintenance logs.
Each scanner is cleaned thoroughly. Panels are removed for repainting and
internal areas are vacuumed. Parts are sanded, painted and detailed using
industrial grade paints and moving parts are checked and lubricated or replaced
as needed. Finally, the entire scanner is reassembled and its fit and finish are
checked.
A final inspection covers all functionality and cosmetic elements to ensure
that the unit reaches or exceeds all OEM standards. An FDA 2579 form is issued
and accompanies the refurbished scanner.
Warranties on refurbished CT
scanners generally cover parts and labor. Most companies will send a
technician to repair any malfunction at the customer site within a limited time
span. Routine maintenance may be covered as well.\\
