Publication number: 20230029695Abstract: The present invention relates to a radiopharmaceutical distribution image generation system and method using deep learning and, more specifically, to a radiopharmaceutical distribution image generation system and method using deep learning, wherein dynamic medical images collected from multiple patients and a time-radiation dose distribution curve for each organ can be learnt through a deep learning network and a spatial distribution image of a radiopharmaceutical can be generated from a static medical image acquired from a specific patient. According to the present invention, even when a medical image is acquired only for a specific time after a radiopharmaceutical is injected into a patient, a spatial distribution image of the radiopharmaceutical can be acquired across the entire time by usin g the deep learning network, and quantitative analysis of the radiopharmaceutical can be performed by calculating a time-radiation dose distribution curve on the basis thereof.Type: ApplicationFiled: July 2, 2020Publication date: February 2, 2023Inventors: Sang Keun WOO, Sang Moo LIM, Kyo Chul LEE, Wook KIM

Patent number: 11424047Abstract: A method of producing actinium by using liquefied radium includes producing Ac-225 using Ra-226 of a liquefied state, moving the produced Ac-225 in a liquefied state after Ac-225 is produced, and separating Ac-225 and reusing Ra-226. As a result, a nuclear reaction process of Ac-225 may be performed and loss of Ra-226 may be minimized. Further, such a method may improve safety by including a radon collection unit which is capable of discharging and isolating radon produced from Ra-226, thereby preventing radiation exposure due to radon.Type: GrantFiled: June 30, 2020Date of Patent: August 23, 2022Assignee: KOREA INSTITUTE OF RADIOLOGICAL & MEDICAL SCIENCESInventors: Se Young Oh, Sang Moo Lim, Kyo Chul Lee, Joo Hyun Kang
