This paper describes an MPEG-2 encoder architecture based on a hard-wired LSI with a control MPU. All basic functions of MPEG-2 MP@ML video compression are integrated in the dedicated LSI. For the motion estimation, a horizontally subsampled, diamond search was employed as a simpli ed rst search step. It can reduce operations to 20% of the full-search, with(More)
Excess acquisition counts were often obtained by the current image acquisition of 30 minutes after 123I-ioflupane administration in a dopamine transporter study. The purpose of this study was to calculate the minimum acquisition time while retaining sufficient image quality, which could be adjusted for individual characteristics. Fifty patients who(More)
Introduction As semiconductor lithography development accelerates, the requirements for photomasks become more and more stringent. This is especially true for mean to target (MTT), uniformity of the critical dimension (CD) and tolerated defect size. According to the latest ITRS roadmap shown in Table 1, the specifications for photomasks of 130 nmlithography(More)
We previously developed a new enzyme-targeting radiosensitization treatment named Kochi Oxydol-Radiation Therapy for Unresectable Carcinomas, Type II (KORTUC II), which contains hydrogen peroxide and sodium hyaluronate for injection into various types of tumors. For breast cancer treatment, the radiosensitization agent was injected into the tumor tissue(More)
