The introduction of the "Picture Archiving and Communications System (known as
PACS)," provides many benefits, including the application of C.A.D., (Computer
Aided Diagnosis). Clinically, this allows for the measurement and design of an
operation to be easily completed with the CRT monitors of PACS rather than with
film, as has been customary in the past.
Under the leadership of the Department of Neurosurgery, Akita University School
of Medicine, and Southern Tohoku Research Institute for Neuroscience, Koriyama, new
computer aided functions with EFPACS (Fuji Electric's PACS) have been developed for
use in clinical neurosurgery. This image processing is composed of three parts as
(1) Automatic mapping of small lesions depicted on Magnetic Resonance (or MR)
images on the brain atlas.
(2) Superimposition of two angiographic films onto a single synthesized image.
(3) Automatic mapping of the lesion's position (as shown on the. CT images) on the
processing image referred to in the foregoing clause 2.
The processing in the clause (1) provides a reference for anatomical estimation.
The processing in the clause (2) is used for general analysis of the condition of a
disease. The processing in the clause (3) is used to design the operation. This
image processing is currently being used with good results.
