PURPOSE To evaluate the ability of coronary computed tomographic angiography (CCTA) to predict the need of coronary revascularization in symptomatic patients with stable angina who were referred to a cardiac catheterization laboratory for coronary revascularization. MATERIALS AND METHODS Pre-angiography CCTA findings were analyzed in 1846 consecutive(More)
This paper presents a development of automatic complementary metal-oxide-semiconductor (CMOS) camera inspection system to examine defects. The image capture board based on embedded linux using system-on-a-chip (SoC) and a complex programmable logic device (CPLD) is developed to capture CMOS sensor data. The captured sensor data is transferred to the host(More)
