We confirmed that the gamma camera had sufficient sensitivity and high quantitative accuracy for example, a weak hot spot (0.9 μSv/h) around a tree root could be detected within 45 min in a low dose rate field test, and errors of measured dose rates with point sources were less than 7% in a dose rate accuracy test.Ī clinical gamma camera-based pinhole collimated system for high resolution small animal SPECT imagingĮnergy Technology Data Exchange (ETDEWEB) From the sensitivity test, we found that the effective sensitivity was about 21 times higher than that of the gamma camera for high dose rate fields which we had previously developed. We tested basic performances of the developed gamma camera and carefully examined effects of the three methods. In order to improve the sensitivity of the pinhole type semiconductor gamma camera, we adopted three methods: a signal processing method to set the discriminating level lower, a high sensitivity pinhole collimator and a smoothing image filter that improves the efficiency of the source identification. We developed a pinhole type gamma camera, using a compact detector module of a pixelated CdTe semiconductor, which has suitable sensitivity and quantitative accuracy for low dose rate fields.

He continued to chart well into the 2010s, with his 2014 studio album Oda Biyori ("Oda Weather") going to number three and his 2016 compilation Ano Hi Ano Toki ("That Day, That Time") to number one.Patient restraining device for the pinhole collimator and gamma scintillation camera Of his studio albums, four went to number one the best selling was 1992's Sometime Somewhere. ![]() As of 2016 he had released nine original studio albums, two cover albums, and five compilations, including 2002's hugely successful Jiko Best ("Personal Best"), which sold over two million copies. Oda, was released in 1986, and over the years he released many more. His albums were just as popular the first, K. He released a number of hit singles, including "Love Story wa Totsuzen Ni" ("Love Stories Are Sudden"), the theme song to the 1991 TV drama Tokyo Love Story, which was a multi-million seller, becoming the eighth best-selling single in Japanese history. The former leader of Japanese folk-rock powerhouse Off Course, Kazumasa Oda (born September 20, 1947) began his solo career in 1985.
