A solid state radiation detector having an improved method of reading data from individual sensors and an x-ray machine configured with such a solid state radiation detector. At least one sensor of the solid state radiation detector is designated as a reference sensor. The output of the reference sensor is read until it reaches a predetermined threshold.

Alternatively, once the output of the reference has reached the predetermined threshold, the output of that reference continues to be monitored to determine when the output of the reference sensor falls below a second predetermined threshold. At approximately that time, all sensors of the solid state radiation detector are read.

Method and apparatus for multi-layered high efficiency mega-voltage imager

A multi-layered mega-voltage digital imager is disclosed. In one embodiment, the radiation to particle conversion and particle to electricity conversion is paired as a modular entity. The entity is replicated on top of each other as a layered unit to build an imager with increased resolution and efficiency. Due to this paired replication, sub-images from each replicated pair may be selectively combined and processed to enhance the quality of the image. By varying and adding components at each layer, a different dose rate, and increased resolution, energy sensitivity and efficiency are achieved. The multilayered approach is cost effective and removes problems associated with traditional high efficient MV imagers used for high energy radiations.

Furthermore, in the scintillator panel (2A), an organic resin layer (12) is formed in such a manner as to cover one surface (11a) and the sides (11c) of the glass substrate (11). According to this configuration, the glass substrate (11) is reinforced, and chipping and cracking of edge portions is minimized. Moreover, stray light from the sides (11c) of the glass substrate (11) can be effectively prevented, and the penetration of light to the other side (11b) of the glass substrate (11) is maintained due to the fact that the organic resin layer (12) is not formed on the other side (11b) of the glass substrate (11).

Radiation detectors and energy discriminating apparatus and methods using such detectors

An energy discriminating apparatus and method is disclosed for use in connection with digital radiography and fluoroscopy. In use of the detection system and method an x-ray source is actuated to direct x-rays through a patient's body, the x-rays including both higher and lower energy radiation. A first detector element (22), including a plurality of segments, is positioned opposite the source to receive and respond predominantly to x-rays in a lower energy range, the remaining x-rays, being generally of higher energy, passing through the first detector element. A second detector element (24), also including a plurality of segments, each segment including a phosphor coating layer (26, 28) and a sensor (30, 32), is positioned to receive and respond to the higher energy radiation passing through the first element. The sensors are coupled respectively to each detector element segment for substantially simultaneously sensing the response and spatial location, relative to the detector elements, of radiation to which each detector element respectively responds. A filter element (36) is interposed between the first and second detectors to enhance discrimination in the energy response of the respective detector elements. Particular preferred detector phosphor materials are identified. The sensors produce separately and simultaneously information representing patterns of relatively lower and higher energy emergent from the patient's body. Digital data processing and conversion equipment responds to the sensors to produce digital information representing each of said images, which can be digitally processed to enhance image characteristics.
