A method for scaling a scattered ray intensity distribution in a multi bulbs X-ray CT apparatus configured to irradiate a subject with X-rays from a plurality of X-ray generation sections, respectively and configure a cross-sectional image of the subject by detecting the X-rays passing through the subject. A first difference is achieved, the first difference being the difference between a real data of X-ray intensity achieved by passing of X-rays through the subject, the X-rays being radiated from the plurality of the X-ray generation sections, respectively and an opposed data of X-ray intensity achieved by passing of these X-rays through the subject at the same position in an opposite direction, a second difference between scattered ray intensity included in the real data and scattered ray intensity included in the opposed data being achieved. Primary scattered ray included in the real data of the X-ray intensity achieved by passing of the X-rays through the subject, the X-rays being radiated from the plurality of the X-ray generation sections, respectively are estimated. Primary scattered ray included in the opposed data of the X-ray intensity achieved by passing of the X-rays through the subject at the same position in an opposite direction, respectively, and performing scaling the primary estimated scattered ray intensity distribution on the basis of a ratio between the first difference and the second difference are estimated.

According to one embodiment, a plaque region extracting apparatus includes a blood vessel wall data extracting unit, an intermediate image data generating unit, an enhancement processing unit, a plaque extracting unit. The blood vessel wall data extracting unit extracts first image data including a blood vessel wall from image data acquired by imaging a subject including blood vessels. The intermediate image data generating unit filters an intermediate region in the first image data to generate intermediate second image data. The enhancement processing unit processes the difference between the first image data and the second image data to generate third image data. The plaque extracting unit extracts a plaque in the blood vessel on the basis of the third image data.
摘要:
A flexible printed circuit substrate is bent in a flattened rectangular C-shape and electronic parts generating heat are mounted on the inner surface of a central portion of the C-shaped substrate. Then a radiating heat-sink plate is adhered on the outer surface of that central portion. Temperature-sensitive electronic parts are mounted on one end portion of the C-shaped substrate and parts consisting of a power supply circuit are mounted on the other end portion. Then the entire assembly is accommodated in a housing having a connector.

摘要:
An angular rate sensor detects an angular rate which is produced when a mobile body such as a motor vehicle moves. The angular rate detecting device comprises at least two angular rate sensors housed in a case perpendicularly to each other. The angular rate sensor comprising a pair of vibratory units which are interconnected by a connector in a tuning-fork configuration. The vibratory units of the angular rate sensors are vibrated at different frequencies. The angular rate sensors may be accommodated in a damper block, which may be housed in the case. Since the angular rate sensors are housed in the single case, the angular rate detecting device is compact in structure and small in size. With the angular rate sensors accommodated in the damper block, they are protected from resonance, crosstalk interferences, and noise, and hence can produce reliable detected output signals.

An electronic circuit module comprises a case, first and second substrates disposed in the case on opposite inner walls with a gap therebetween and, a flexible film having a circuit pattern thereon and attached at a part to the first substrate and attached at another part to the second substrate. A first group of electronic components including a heat-generating component are mounted on the film part attached to the first substrate. A second group of electronic components including a low-heat-resistive component are mounted on the film part attached to the second substrate. The gap between the first and second substrates is filled with a resin layer, preferably a foam resin layer, having a low heat conductivity so as to prevent a heat transfer from the heat-generating part to the low-heat-resistive part.
