Title: Innovations by Samuel Packer in Nuclear Medicine
Introduction
Samuel Packer is a notable inventor based in Great Neck, NY (US), recognized for his contributions to the field of nuclear medicine. He holds a total of four patents, showcasing his innovative approach to medical technology. His work primarily focuses on developing advanced imaging techniques and radiation sources for cancer detection and treatment.
Latest Patents
One of Packer's latest patents is a flexible nuclear medicine camera and method of using it. This invention involves a nuclear medicine camera designed to photographically record radioactive decay particles emitted from a source, such as small, previously undetectable breast cancer within a patient. The camera features a flexible frame that contains a window, photographic film, and a scintillation screen. The frame is designed to flex and follow the contour of the examination site on the patient, ensuring that the window is in close contact with the skin. This design reduces the distance between the film and the radiation source, allowing for improved imaging. The exposure time for this camera may extend over several days, facilitating early qualitative detection of small malignant neoplasms.
Another significant patent by Packer involves the use of samarium-145 as a radiation source. This new radiation source has energies slightly above those of I-125 and a half-life of 340 days. Samarium-145 is produced through neutron irradiation of SM-144 and is particularly useful as an implanted radiation source in photon activation therapy for malignant tumors. This method activates stable I-127 contained in IdUrd accumulated in the tumor, leading to radiation sensitization and irreparable damage to tumor cells. Additionally, this source serves as a brachytherapy option.
