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.
