抄録

Scan conversion memory (SCM) has been applied to a method of the storage and the display for radioisotope imaging. Scan data were fed in SCM as pulse signal with X and Y axis from the scinti-scanner or the scinti-camera. Electric charge on the target of SCM is directly proportional to pulse density. A display by the TV system was immediately executed after the record of a radioisotope image. If necessary, seven additive color display to the image density was able to be obtained by a simple color slicer, and image can be hard-copied by a video hard-copy printer.<BR>The characteristics of the SCM has been experimentally clarified as follows: practical resolution was 700 line/TV, ten levels gray scale were discriminated on the video monitor, uniformity measured by an oscilloscope was less than 20%, and dead time of the pulse interval at the full scale signal was 5μsec.<BR>The SCM scnitigrams were observed as representation closely resembling conventional film scintigrams. Superimposed image of a X-ray picture and a radioisotope image can be realized by using the SCM, for an increase in anatomical localization on reading images. SCM scintigram can be applied fast and pre viewer of radioisotope imaging.
