摘要： A thin radiation detector with a high sensitivity is described. The radiation detector has light receiving elements receiving lights emitted by scintillators, performs a photoelectric conversion by using an avalanche multiplication film formed by amorphous selenium, and reads signals by using electron beams constantly discharged from a plurality of electron beam emitting sources called as a field emission array. The avalanche multiplication film formed by amorphous selenium is quite thin and has a simple structure, so it can be formed compactly and realized at a low cost. In addition, a signal amplification degree is approximately 1000 times, so an expensive low noise amplifier or a dedicated temperature adjusting mechanism is not required, and a quantum efficiency is sufficient for a wavelength of 300˜400 nm.

摘要： A problem of local pin-hole defects generated in avalanche multiplication is avoided. Before an anode and a cathode are assembled as a light receiving element, a position of a pin-hole defect is specified by a vacuum container for specifying a defect position having a previously prepared field emission array for inspection. If the cathode is a field emission array when the anode and cathode are assembled as a light receiving element, the anode and cathode are assembled such that a field emission chip corresponding to the position of the pin-hole defect does not discharge an electron beam to the field emission array serving as an actual detector.

摘要： A radiation detecting cassette is disposed in a desired position between a bed and a patient in an operating room. After a detector-side connector and a bed-side connector are connected to each other by a cable, an image capturing apparatus captures and records radiation image information of the patient in a radiation detector. The recorded radiation image information is transmitted from a transceiver of the bed to a console by way of wireless communications, then processed by the console, and transmitted to a display device, which displays a radiation image based on the supplied radiation image information.

摘要： When light is incident on the photoelectric surface of this electron tube, photoelectrons are emitted. These photoelectrons are accelerated and incident on an electron beam irradiation diode. A reverse voltage of about 100 V is applied to the electron beam irradiation diode to form a depletion region almost throughout an anode layer and near the p-n junction interface of a silicon substrate. The incident accelerated electrons release a kinetic energy in a heavily doped p-type layer having an electron incidence surface and the depleted anode layer to form electron-hole pairs. In this case, since the heavily doped p-type layer having the electron incidence surface is very thin, the energy is hardly released in this layer, and almost all energy is released in the depletion region. Signal charges extracted from the electron-hole pairs formed upon releasing the energy are output as a signal from two electrodes.

摘要： A two-dimensional radiation detecting method and apparatus for converting incident radiation in a two-dimensional distribution into electric signals. The apparatus includes a target structure and an electron beam scan mechanism. The target structure has a fluorescent element, transparent electrodes in stripes and a photoconductive film laminated in the stated order on a substrate. The electron beam scan mechanism has a plurality of linear cathodes, backing electrodes for taking electron beams from a selected linear cathode, a vertically converging electrode, vertically deflecting electrodes, accelerating electrodes and a decelerating electrode. The electron beam scan mechanism simultaneously projects the electron beams distributed horizontally to one horizontal line on the photoconductive film, and then shifts the electron beams vertically, to read a two-dimensional distribution of potentials on the photoconductive film.

摘要： An infra-red imaging device consisting of two sheets of interconnected disks of piezoelectric material, at least one of which has a ferroelectric transition temperature. A metal foil is provided between the sheets and mutually parallel, conductive strips are provided on both outer surfaces of the assembly thus formed, the direction of the strips on the one surface differing from that of the strips on the other surface. A generator for periodic signals which can be sequentially connected to each strip on one of the surfaces of the first sheet generates therein, via a piezoelectric effect, ultrasonic vibrations which are intercepted by the other sheet which converts these vibrations into electric signals. These signals are amplified and carry the image to be examined.
