Abstract: An X-ray detector according to embodiments is an X-ray detector of a direct conversion type in which a plurality of X-ray detection elements are arranged in a column direction and a channel direction and voltage is applied between anodes and cathodes. The X-ray detector includes processing circuitry. The processing circuitry performs control so as not to use, for generation of image data, data from the X-ray detection elements in end portions in one of the column direction and the channel direction of the X-ray detection elements, and so as to use, for generation of image data, data from the X-ray detection elements in other than the end portions.

Abstract: An X-ray CT apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to obtain initial temperature information of a photon counting detector before a main scan, information about the shape of a subject, and a scan condition of the main scan. The processing circuitry is configured to estimate a temperature change of the photon counting detector to be observed when the main scan is performed, on the basis of the initial temperature information, the information about the shape of the subject, and information about the scan condition of the main scan. The processing circuitry is configured to judge whether or not it is possible to perform the main scan, on the basis of the temperature change and the initial temperature information.

Abstract: Display means capable of displaying a plurality of objects, detection means for detecting a body, specifying means for specifying a first object displayed in the display means by a movement of the body, measurement means for measuring a distance between the body and the display means, and display control means for determining whether the first object or a second object which is different from the first object is displayed on a front side in the display means in accordance with the distance are provided.

Abstract: A digital television (101) which allows the user to view a digital broadcast program receives a digital broadcast signal, and outputs it on the display screen. The digital television sequentially stores print information of the broadcast program in response to a predetermined output instruction during viewing of the broadcast program. The digital television transmits the stored print information to a printer in response to a print start instruction after the predetermined output instruction. In this way, the digital television sequentially saves print data of the broadcast program that the user is viewing, allows the user to select required data later, and can print the selected data all together.
