Abstract: High sensitivity HARP pickup tubes, developed by NHK Labs. for the HDTV cameras, have about 80 times (Super version) and 640 times (New Super version) as sensitive as a conventional camera tube, using an avalanche multiplication effect in the amorphous selenium target. The HARP HDTV camera is a powerful tool not only in the outside broadcasting such as night time emergency news gathering, but also in scientific applications such as deep sea image acquision. Applications of the camera in the medical field was executed by NHK Engineering Services, Inc. To visualize an X-ray image, ordinary image intensifier or CCD camera is not appropriate because of its poor resolution or sensitivity. We have succeeded in detecting the X-ray image using the high sensitivity HARP HDTV camera. The camera is appropriate in both high sensitivity and high resolution for identifying micro-vessels under the size of some dozens of μ m in various organs, and the system is proved to be useful for clinical applications.
