摘要： A gamma ray scintillation camera generating (X,Y) spatial coordinate and Z energy signals relative to detected radiation events. The system provides for calibration of the camera Z signal response as a function of camera face location. The camera signals are converted to their digital equivalents subsequent to which the apparent coordinate locations of detected events as determined by the camera are corrected to their true spatial coordinates based upon correction information stored in the system.

摘要： A method and apparatus by which video signals can be converted to digitized values and stored in memory. Means are provided for continuous digitization of successive images which may be stored in computer memory in real time. Additionally, means are provided for compression of adjacent picture elements to produce a spacially compressed image which takes up less memory space. Also disclosed are means for compressing successive frames so as to produce a temporally compressed image.

摘要： A rectilinear scanner for detecting radiation in a plurality of channels utilizing a collimator. Each of the channels receives information from a different portion of the collimator. Information separately received is separately massaged and later collated to present a common image. The information is processed by apparatus in a data processing system. This system has means for massaging analog signals corresponding to gamma radiation counts. This system has means for converting such analog signals to digital signals. This system has means interfacing the digital signals into an address register that communicates directly via data busses to core memory of a central processing unit by cycle stealing. This system has means deriving clinically significant information by computation on the resultant digital data. This system has means storing, retrieving, and displaying the resultant digital data and the resultant derivations therefrom collectively. This is done in such a manner as to allow time sequencing of the aforementioned operations such that the aforementioned operations can be interleaved on a real time basis.
