Publication number: 20100198063Abstract: Herein are described methods and tools for acquiring accurately co-registered PET and TRUS images, as well as the construction and use of PET-TRUS prostate phantoms. Ultrasound imaging with a transrectal probe provides anatomical detail in the prostate region that can be accurately co-registered with the sensitive functional information from the PET imaging. Imaging the prostate with both PET and transrectal ultrasound (TRUS) will help determine the location of any cancer within the prostate region. This dual-modality imaging should help provide better detection and treatment of prostate cancer. Multi-modality phantoms are also described.Type: ApplicationFiled: November 19, 2009Publication date: August 5, 2010Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Jennifer S. Huber, William W. Moses, Jean Pouliot, I-Chow Hsu, Qiyu Peng, Ronald H. Huesman, Thomas F. Budinger

Patent number: 7535797Abstract: An ultrasound method of measuring displacement with high resolution includes transmitting a pair of Golay's complementary sequences or other complementary sequences, receiving echoes from the object and performing pulse compression of the two sequences of echoes. The displacement of the object between the two transmissions is derived from the residual clutter signals around the mainlobe of the compressed pulse output. Furthermore, movement velocity, thickness, strain, elastic stiffness, and viscous damping of the object or regions of the object can be determined subsequently.Type: GrantFiled: June 20, 2006Date of Patent: May 19, 2009Assignee: RehabtekInventors: Qiyu Peng, Li-Qun Zhang
