With a total of three patents to his name, his work focuses on enhancing the capabilities of laparoscopic procedures.
Latest Patents
One of his latest patents is titled "Electronic collimation and depth detection in a side-viewing laparoscopic probe for the detection of high energy gamma radiation." This invention discloses a necessary detector configuration and mathematical algorithms to implement a lateral field of view in a gamma detection probe designed for laparoscopic use. The diameter of the probe is limited to 12 mm, and it employs a hybrid collimation design that combines electronic collimation and metallic shielding. This allows the probe to detect gamma emissions ranging from 15 KeV to 1.0 MeV. The design includes 1.52 mm tungsten shielding to collimate the primary detector in the lower energy range, while two additional detectors provide electronic collimation and depth detection.
Another significant patent is focused on "Hybrid collimation to limit the field of view for gamma detection probes at high and low energies." This hybrid collimated probe incorporates two detectors made of scintillating crystal or semiconductor material, such as Cadmium-Zinc-Telluride (CZT). The count rate measured on the rear detector is corrected for the shielding effect of the front detector, ensuring accurate readings. This innovative approach also accounts for background radiation, enhancing the probe's effectiveness in clinical settings.
