Abstract: The present 3D-Flow OPRA is a revolutionary electronic instrument for multiple applications: advancing science, saving lives, finding and tracking fast moving objects, etc. It allows to build a flexible, scalable, technology-independent, cost effective powerful tool to uncover the unknown and to confirm or exclude the existence of a subatomic particle predicted by theoretical physicists. When used for Medical Imaging applications the 3D-Flow OPRA allows to accurately measure minimum abnormal biological processes of diseases at an early curable stage such as cancer in a 3D-CBS (3-D Complete Body Screening), improving diagnosis and prognosis to maximize reduction of premature deaths and minimize cost per each life saved. Both instruments, the 3D-Flow OPRA and the 3DCBS can benefit from the additional ER/DSU invention also described in this non-provisional patent application, which allows to record real data from detectors.

Abstract: The present invention is directed to a system, method and software program product for implementing an efficient, low-radiation 3-D Complete-Body-Screening (3D-CBS) medical imaging device which combines the benefits of the functional imaging capability of PET with those of the anatomical imaging capability of CT. The present invention enables a different detector assembly, and together they enable execution of more complex algorithms measuring more accurately the information obtained from the collision of the photon with the detector. The present invention overcomes input and coincidence bottlenecks inherent in the prior art by implementing a massively parallel, layered architecture with processor separate stacks for handling each channel. The prior art coincidence bottleneck is overcome by limiting coincidence comparisons to those with a time stamp occurring within a predefined time window.

Abstract: A single channel or multi-channel system that requires the execution time of a pipeline stage to be extended to a time longer than the time interval between two consecutive input data. Each processor in the system has an input and output port connected to a “bypass switch” (or multiplexer). Input date is sent either to a processor, for processing, or to a processor output port, in which case no processing is performed, through a register using at least one clock cycle to move date from register input to register output. For a single channel requiring an execution time twice the time interval between two consecutive input data, two processors are interconnected by the bypass switch. Data flows from the first processor at the input of the system, through the bypass switches of the interconnected processors, to the output. The bypass switches are configures with respect to the processors such that the system data rate is independent of processor number.

Abstract: The present invention is directed to a system and method for efficiently and cost effectively determining an accurate depth of interaction for a crystal that may be used for correcting parallax error and repositioning LORs for more clear and accurate imaging. The present invention is directed to a detector assembly having a thin sensor (e.g., APD) deployed in front of the detector (the side where the radioactive source is located and the photon is arriving to hit the detector) and a second sensor (APD or photomultiplier) on the opposite side of the detector. The light captured by the two interior and exterior sensors which is proportional to the energy of the incident photon and to the distance where the photon was absorbed by the detector with respect to the location of the two sensors, is converted into an electrical signal and interpolated for finding the distance from the two sensors which is proportional to the location where the photon hit the detector.
