Patent number: 11828891Abstract: A scintillation block detector employs an array of optically air coupled scintillation pixels, the array being wrapped in reflector material and optically coupled to an array of silicon photomultiplier light sensors with common-cathode signal timing pickoff and individual anode signal position and energy determination. The design features afford an optimized combination of photopeak energy event sensitivity and timing, while reducing electronic circuit complexity and power requirements, and easing necessary fabrication methods. Four of these small blocks, or “miniblocks,” can be combined as optically and electrically separated quadrants of a larger single detector in order to recover detection efficiency that would otherwise be lost due to scattering between them.Type: GrantFiled: October 9, 2019Date of Patent: November 28, 2023Assignee: Siemens Medical Solutions USA, Inc.Inventors: Robert A.

Patent number: 11154262Abstract: Detector heads in a gantry of a medical imaging apparatus are pivotally-coupled to mounting rails oriented axially about the gantry's axial centerline. Radial alignment blocks facilitate alignment and fixation of detector faces circumferentially transverse and normal to a radius projecting from the gantry's axial centerline. A column of detector heads on a common rail are separated by axial stop blocks, for precise axial separation. Abutting detector heads on a common mounting rail are slaved to another previously transverse-aligned detector through a common, shared radial alignment block. Plural, stacked gantry backplanes are fabricated simultaneously, assuring common circumferential and radial co-registration of plural mounting rails relative to the axial centerline of the gantry. Adjustable orientation of the detector heads compensates for tolerance stack up during final assembly of the gantry, so that the detector heads are mutually aligned in a uniform grid of axial columns and circumferential rows.Type: GrantFiled: June 25, 2020Date of Patent: October 26, 2021Assignee: Siemens Medical Solutions USA, Inc.Inventors: James L.
