An advantage of a RLD (Reconfigurable logic device) such as an FPGA (Field programmable gate array) is that it can be customized after being manufactured. However, there is a problem related to standby power when using it in SoC used in embedded systems. Power gating, which is one of the power reduction techniques, is difficult to use in SRAM-based RLDs(More)
BACKGROUND The prognostic value of rest 201Tl/stress (99m)Tc-tetrofosmin myocardial perfusion single-photon emission computed tomography (SPECT) for the prediction of future hard cardiac events, including acute myocardial infarction (AMI), unstable angina (UAP) and cardiac death, and the implications for risk stratification has not yet been defined in a(More)
BACKGROUND The prognostic value of ECG-gated rest 201Tl/stress 99mTc-tetrofosmin myocardial perfusion single-photon emission computed tomography for the prediction of acute coronary syndrome (ACS: myocardial infarction (MI) and unstable angina (UA)) and the implications of ejection fraction (EF) has not yet been defined in Japanese. METHODS AND RESULTS(More)
BACKGROUND Usefulness of diastolic dysfunction after adenosine stress for detecting coronary stenosis has not been defined. The diagnostic accuracy of a combination of myocardial perfusion and diastolic function, as defined by prolongation of time to peak-filling rate (TTPF)/R-R and myocardial perfusion alone for the detection of coronary restenosis, was(More)
Isolated subvalvular pulmonary stenosis (ISPS) is a rare condition, and it is often accompanied by hypertrophic cardiomyopathy. However, diagnosis of ISPS is obscure because of difficulty in comprehension of three-dimensional cardiac anatomy. Whole-heart magnetic resonance imaging (MRI) is a new, totally non-invasive technique which allows not only(More)
