[en] The CAMAC system is attracting attention as a standard module for measurement and control. It is an interface capable of processing a large amount of data with high speed and is used mainly in the field of nuclear physics. Toshiba now has developed CAMAC modules and its software which have a microcomputer for the nucleus, and established quality assurance through simulation tests, environmental tests, etc. Application of this CAMAC to the measurement and control systems in nuclear fusion plants is now under promotion along with the development of the module series.

[en] To elucidate the multi-detector row computed tomography (MDCT) findings of extrapancreatic nerve plexus (PLX) invasion by pancreas head carcinoma (PhC) by ''point-by-point'' correlation with en bloc pathological specimens and to assess their diagnostic accuracy. Each pathological section of PhC and adjusted double oblique multiplanar reconstruction MDCT images were correlated in 554 sections from 37 patients. The diagnostic accuracy of the MDCT patterns derived was assessed by blind reading. PLX invasion with fibrosis showed mass or strand shape (85.6%) or coarse reticula (13.3%). The CT findings were divided into fine reticular and linear, coarse reticular, mass and strand, and nodular patterns. PLX invasion was revealed pathologically in 92% of the regions of investigation showing the mass and strand pattern and 63% of the coarse reticular pattern (all continuous with PhC), and they were highly suggestive of PLX invasion by PhC on MDCT images (p < 0.001). Sensitivity, specificity, accuracy, and positive and negative predictive values of these MDCT findings in the diagnosis of PLX invasion were 100% (25/25), 83.3% (10/12), 94.6% (35/37), 92.6% (25/27) and 100% (10/10), respectively. The mass and strand pattern and the coarse reticular pattern continuous with PhC on MDCT images were highly suggestive of PLX invasion by PhC. (orig.)
