Abstract
A device and methods for performing a simulated CT biopsy on a region of interest on a patient. The device comprises a gantry (22) configured to mount an x-ray emitter (24) and CT detector (26) on opposing sides of the gantry, a motor (28) rotatably coupled to the gantry such that the gantry rotates horizontally about the region of interest, and a high resolution x-ray detector (172) positioned adjacent the CT detector in between the CT detector and the x-ray emitter.
Claims12
A system for performing a simulated computed tomography (CT) breast biopsy, comprising:
- an x-ray source coupled to a gantry that rotates around a subject's breast;
- a first detector and a second detector both coupled to said gantry and positioned to receive x-ray beams from the x-ray source;
- and
- a processor communicatively coupled to said first and second detectors and configured to:
- generate, based on a first x-ray beam received by the first detector, a first CT projection dataset of the subject's breast at a first spatial resolution;
- identify, based on the first CT projection dataset, a location of a possible tumor in the subject's breast;
- generate, based on a second x-ray beam received by the second detector, a second CT projection dataset of a portion of the subject's breast proximate to the possible tumor at a second, higher spatial resolution;
- and
- generate, based on at least the second CT projection dataset, a high-resolution image of the portion of the subject's breast.
