Abstract: While conductive adhesives 60 are provided between element electrodes of a pyroelectric element 10 and board electrodes of an installation board 20, the conductive adhesives 60 are hardened to connect between the element electrodes of the pyroelectric element 10 and the board electrodes of the installation board 20.

Abstract: A diagnostic apparatus for diagnosing the circulatory system of a patient, including an X-ray diagnostic system and an ultrasonic diagnostic system. The ultrasonic diagnostic system has an ultrasonic catheter for insertion into the circulatory systems of the patient and for scanning a circulatory organ with an ultrasonic wave to thereby an ultrasonic tomogram. A roadmap image is obtained prior to the ultrasonic diagnosis. When the ultrasonic catheter is inserted into the circulatory system of the patient, the X-ray diagnosis is performed to obtain a live image of the circulatory system which includes a picture of the catheter and is displayed overlapped on the roadmap image. The ultrasonic catheter is inserted into the circulatory system of the patient while the location of the catheter is monitored from the overlapped display of the live image and the roadmap image.

Abstract: In a radiation image read-out method and apparatus, preliminary read-out is conducted prior to final read-out for adjusting read-out conditions in the final read-out and/or image processing conditions for a radiation image stored on a stimulable phosphor sheet. When the radiation image is read out from the stimulable phosphor sheet subjected to subdivision image recording, an image signal at a subdivision unexposed to a radiation is eliminated from preliminary read-out image signals, which are obtained by the preliminary read-out, on the basis of information on the subdivision image recording. The read-out conditions in the final read-out and/or image processing conditions are adjusted based on the remaining preliminary read-out image signals.

Abstract: With this radiation photographing apparatus, radiation image converting panels (or IPs) of the same size are used. X-rays shot through an X-ray tube are focussed to have a predetermined size by an X-ray diaphragm to expose a patient and to expose the IP with the penetrated X-rays. This IP is picked up from a feed magazine by a spot shot device, and is supported and set at a photographing position by a holder. The exposed IP is set in an image reading device. Only that area which has been exposed by X-rays is irradiated by a laser beam in the reading device. This area is scanned by the laser beam, and phosphorescence is emitted from the IP when it is irradiated and converted to an electric signal by a photodetector. This detection signal is sent to a image reproducing device to display the X-ray image.
