Patent number: 12000970Abstract: A system for charge sharing compensation for a photon counting detector. A plurality of comparators, each configured to generate comparator output data based on a threshold value, a plurality of energy bins, each of the plurality of energy bins coupled to one of the plurality of comparators, and a coincidence logic coupled to two or more of the plurality of comparators and configured to receive comparator output data associated with two or more of a plurality of pixels. The comparator output data for each pixel indicates when a signal associated with the pixel crosses a threshold value. The coincidence logic is configured to generate a coincidence output when the comparator output data for a first pixel is received within a predetermined time interval of the comparator output data for a second pixel. The system includes a coincidence counting bin coupled to the coincidence logic and configured to receive the coincidence output and generate count data based on the coincidence output.Type: GrantFiled: May 1, 2020Date of Patent: June 4, 2024Assignee: The Regents of the University of CaliforniaInventor: Scott S.

Patent number: 10850128Abstract: A device for performing tomosynthesis in real time is described. Multiple imaging sources (such as x-ray sources) may be energized in parallel and collimated towards a field of view. Objects within the field of view cast shadows onto one or more detectors. An imaging system may read the one or more detectors and acquire multiple views corresponding to the multiple imaging sources to produce a reconstructed image of an object of interest. From this reconstructed image, a target of the radiation therapy can be located, and the delivery of the radiation can be adjusted, as needed. The approach provides a real-time tomosynthesis design that can produce enhanced contrast for guidance of, for example, lung tumor treatment. Higher frame rates can be achieved to better compensate for changes in the position of the target during radiation therapy due to, for example, respiratory or cardiac motion.Type: GrantFiled: April 10, 2017Date of Patent: December 1, 2020Assignee: The Regents of the University of CaliforniaInventor: Scott S.

Patent number: 9586840Abstract: The disclosed technology includes systems and methods for clustering particles, especially water contaminants, by liquid-phase electric plasma discharge. According to certain implementations, the discharge may be applied continuously, and may be of relatively low power, e.g., a voltage between 300 V and 5000 V and an amperage between 0.1 A and 1 A. The electrodes introducing the electric discharge may be in a point-to-point configuration and with at least one electrode having a large aspect ratio. In some implementations, one or more of the voltage and amperage of the electric discharge, electrode configuration and aspect ratio, and the conductivity of the medium may enable the generation of plasma containing hydroxyl and other radicals. The radicals may catalyze polymerization of the particles, resulting in an increase in particle size and, thus, improved filterability. The polymerization process may continue after the electric discharge is discontinued or removed from influence of the medium.Type: GrantFiled: April 18, 2013Date of Patent: March 7, 2017Assignee: Georgia Tech Research CorporationInventors: Jeffery S.
