Title: Synchronization of Patient Motion Detection Equipment with Medical Imaging Systems Using a Short Encoded Pulse Sequence Inserted Into a Patient's Electrocardiography (ECG) Gated Input Signal During a List-Mode Image Acquisition. UMMS13-49; Patent Pending.
-
The present invention provides an improved system to correct for patient motion during imaging modalities such as PET and SPECT. Uniquely, this system acquires multiple physiological signals (EKG signals, tomography signals, gross-body motion signals, respiratory motion signals, voluntary motion signals, involuntary motion signals), using a single data channel.
- Technology: Medical Devices
- Applications: Imaging, Computerized medical system
Title: IMAGE RECONSTRUCTION INCLUDING SHIFT-VARIANT BLUR COMPENSATION. UMMS09-53; Patent 8,755,586
-
This patented technology describes an imaging apparatus with improved blur compensation. Blur due to finite detector resolution in various imaging modalities is a significant problem. Specifically, this invention provides an image reconstruction method using an iterative reconstruction method and computing a projection used in the reconstructing by summing ray increments between neighboring planes (P0, P1, P2, . . .) parallel with a detector face (42) with stationary incremental blurring associated with each ray increment computed based on a distance between the neighboring parallel planes. A non-stationary blurring kernel may also be convolved at a plane closest to the detector face to generate a projection incorporating shift-variant blurring.
