<p><P>PROBLEM TO BE SOLVED: To enable an X-ray computer tomograph for scanning in a short time by high-speed rotation to operate with power supplied from a power source with a small power capacity. <P>SOLUTION: A DC/AC inverter 14c converts a first DC voltage into AC voltage. A high-voltage generator 14d uses the AC voltage obtained with the DC/AC inverter 14c to generate AC power for giving birth to X-ray irradiation by an X-ray tube 11a provided at the X-ray computer tomograph. An electric double-layer capacitor 14b accumulates electric energy by a second DC voltage, and the electric energy thus accumulated is output as a third DC voltage. An AC/DC converter 14a makes the electric double-layer capacitor 14b accumulate electric energy during a period when the X-ray irradiation is not carried out, and generates a second DC voltage, during a period when the X-ray irradiation is carried out, so as to be able to obtain the first DC voltage by composition with the third DC voltage. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
