A catheter-type semiconductor detector and associated electric system have been developed, in co-operation with Mitsubisei Electric Corp., for the diagnosis of malignant tumors. We illustrated the mechanism of a new catheter-type semiconductor detector. The performance test of the new catheter-type detector measures 2.5mm in diameter and 150cm in length was made. This detector is small enough to insert in the stomach or esophageal fiberscope. The image of ^<32>P was also abtained by the semiconductor detector connected with a scintiscanner in our laboratory. With this combination we are able to demonstrate with clarity the distribution of ^<32>P in cancerous tissue.
