Medical Applications
of CD-R Take Off
Compact Disc-Recordable
(CD-R) technology is the write-once version of the wildly popular
CD-ROM format. A CD-R disc can hold up to 650 MB of digital data
and can be read back in any of the millions of low-cost CD-ROM
drives commonly installed as standard equipment on most new personal
computers sold. CD-R is widely recognized as offering the lowest
cost per megabyte of any random-access writable data storage medium.
In addition, it is compact, durable, versatile and can used to
reliably archive data for upwards of one hundred years. Further,
because CD-R is a true wirte-once medium, it provides a legal
hard copy of the information stored thereon.
These capabilities
have made CD-R the data storage medium of choice for many vertical
market applications. Whether original electronic data files or
scanned images of paper documents, whether text, graphics, audio
or video, CD-R is being used to store, retrieve and distribute
huge quantities of digital information every day. Banks store
check images, lawyers file legal documents, engineers archive
huge CAD files, and phone companies deliver extensive, detailed
bills to large customers, all using CD-R technology.
Yet no other
application area may offer a better demonstration of the value
of CD-R technology than the medical imaging arena. Many of the
state-of-the-art medical imaging systems and networks are Unix-based,
though this is not always obvious due to the embedded nature of
the systems integration. Young Minds pioneered the Unix CD-ROM
market and continues to lead in the application of CD-ROM and
CD-Recordable technologies in new and innovative markets such
as medical imaging.
Recent advances
in digital imaging technology for medical applications have lead
to an explosion of digital data which needs to be collected, analyzed
and stored, often for an indefinite period of time. Summary data
from previous medical imaging tests are inadequate when tracking
the development or healing of an injury or illness; the original
data must be readily available to allow detailed comparisons.
Further, with the increasing potential of medical liability extending
long after diagnosis and treatment has occurred, the original
data from medical imaging tests which contributed to the diagnosis
and /or treatment becomes invaluable in supporting a physician’s
decision.
Finally, patients
are becoming more mobile, moving from one area to another, or
from one insurance plan to another, often changing doctors along
the way. With the increasing level of digital data content in
patients’ medical records, it becomes important to be able to
transfer such data conveniently between physicians. Unlike any
other writable medium, using CD-R discs allows the digital data
to be read back by very inexpensive and commonly available CD-ROM
drives. This then offers the potential for the data to be accessed
and reviewed on inexpensive, desktop personal computers, at least
one of which is installed in virtually every medical office today.
Young Minds
CD-Recordable technology is being used by leading medical equipment
manufacturers and integrators to apply CD-R technology to medical
applications in two main ways: recording of medical imaging data
onto CD-R discs by hospital or medical testing laboratories for
delivering test results directly to the patient or the patient’s
physician, or for internal near-line archiving, commonly using
a CD-ROM jukebox with a built-in CD-ROM drive, to provide a permanent
archive of all medical imaging tests performed by the medical
facility, while offering immediate access to the data by all authorized
personnel throughout the organization.
CD-R is yet
another tool which can be applied to enable higher-quality, yet
more efficient, use of the limited medical resources available
in our, or any, society. Though this was probably not what the
inventors of CD-R thought it would be used for, it should be gratifying
to them that the medical applications of their invention may provide
great benefits.
