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.
