摘要： An imaging plate comprising a first conductive layer having a plurality of conductive segments arranged thereabout, a photoconductive sandwich structure affixed to the first conductive layer, and a second conductive layer integrally affixed to the side of the photoconductive sandwich structure opposite the first conductive layer. The conductive segments of the first conductive layer are electrically connected to a conductor such that each of the conductive segments are selectively addressable. Each of the conductive segments is a conductive strip separated from adjacent conductive strips by dielectric material. The conductor is an accumulator bar extending across the conductive layer transverse to the conductive strips. A photoconductive bridge conects each of the conductive strips with the accumulator bar. The photoconductive bridge is a photoconductive dot. Each of the photoconductive dots is addressable by a properly positioned photon beam.

摘要： A dosimeter for use in mammographs wherein a plate-like body of electrically non-conductive hard foamed material generates charge carriers in response to exposure to radiation. The body is provided with electrodes which are connected with an energy source. The output signal of the dosimeter is used to regulate the amounts of radiation to which an object is exposed. The entire dosimeter can be installed between the source of radiation and X-ray film or another carrier of images of objects because the dosimeter does not cast a shadow on the film when the object is exposed to radiation.

摘要： Dielectric receptor sheets which are transported seriatim from a tray into the gas-filled interelectrode gap of an ionography imaging chamber are arrested ahead of the chamber, and a corona generating device is moved along each arrested sheet to apply a uniform electrostatic charge to or to neutralize the electrostatic charge of the arrested sheet. Each arrested sheet whose charge is influenced by the corona generating device is attracted by suction to the concave side of an arcuate guide. The corona generating device is mounted on a carrier which is pivotable about an axis including the center of curvature of the concave side of the guide. The carrier further supports a pivotable retainer which moves the central portions of the leaders of successive sheets against the concave side of the guide if the leaders exhibit the tendency to bend or bulge away from the concave side. The marginal portions of sheets which are advanced along the guide extend into arcuate channels which flank the concave side. The treatment by the corona generating device can serve to destroy non-uniform positive or negative charges or to apply uniform background potential.

摘要： Apparatus for X-ray radiography includes a conductive cathode, receiving X-radiation differentially attenuated by passage through an object to be studied, and a conductive anode spaced from the cathode and bearing a sheet of insulative material upon which a charge image of the object is to be formed; and a structured photocathode extending from the cathode towards the anode. The photocathode, formed of cesium iodide and the like, is of relative great thickness and surface area to have large X-ray quantum absorption and photoelectron emission, whereby a lower exposure dosage of X-radiation is required for a radiographic exposure. A plurality of different photocathode structures are disclosed.

摘要： A tomographic image of a selected layer of a stationary object is made by moving the source of X-rays along a first path at one side of the selected layer and by moving an ionography imaging chamber which contains a dielectric receptor sheet along a second path at the other side of the selected layer. The movement of the sheet is synchronized with movement of the source of X-rays and includes a translatory movement in a direction counter to the direction of movement of the source, a pivotal movement to maintain the sheet in a plane which is normal to the central beam of the bundle of X-rays, and a sidewise movement to vary the distance between the selected layer and the sheet so that the length of the projection of selected layer upon the sheet remains unchanged. If the sheet is rectangular, the pivotal movement is performed about an axis which is located in the plane of the selected layer and is parallel to the shorter sides of the sheet.
