Abstract: A CT apparatus includes a plurality of imaging units, a rotation mechanism, and a CPU. The imaging unit includes a radiation source and a radiation detector. The rotation mechanism rotates the plurality of imaging units around a body axis of the subject while maintaining a disposition interval. An imaging control unit of the CPU controls operations of the plurality of imaging units and the rotation mechanism. An angular interval that is determined by a frame rate of the radiation detector and a rotation speed of the imaging unit and that defines an acquisition time of a projection image based on the radiation is the same for the plurality of imaging units. The plurality of imaging units have different phases in a rotation direction, and positions where the plurality of imaging units acquire the projection images are separated by a set angle that is less than the angular interval.

Abstract: A radiation source includes a radiation tube having a cathode which is a cold cathode. An imaging control unit directs the radiation source to intermittently and alternately emit the first radiation having a first energy distribution and the second radiation having a second energy distribution different from the first energy distribution whenever a rotation mechanism rotates the radiation source and a radiation detector by a preset angle. The imaging control unit directs the radiation detector to output a first projection image based on the first radiation and a second projection image based on the second radiation which are obtained by the intermittent emission of the first radiation and the second radiation. An image processing unit generates a tomographic image on the basis of the first projection image and the second projection image.

Abstract: An imaging control unit performs conventional scanning, which directs a rotation mechanism to rotate a radiation source and a radiation detector without changing a positional relationship between a subject, and the radiation source and the radiation detector in a rotation axis direction, directs the radiation source to emit radiation whenever the radiation source and the radiation detector are rotated by a preset angle, and directs the radiation detector to output a projection image, at a plurality of height positions along the rotation axis direction. The image processing unit generates a tomographic image on the basis of the projection images obtained at the plurality of height positions.

Abstract: A CT apparatus includes a plurality of imaging units, a rotation mechanism, a radiation source elevating mechanism, a detector elevating mechanism, and a CPU. The imaging unit includes a radiation source that emits radiation having a quadrangular pyramid shape to a subject and a radiation detector in which a plurality of pixels detecting the radiation transmitted through the subject are two-dimensionally arranged. The rotation mechanism rotates the plurality of imaging units around a body axis of the subject. The radiation source elevating mechanism and the detector elevating mechanism change an interval between the plurality of imaging units in a rotation axis direction. An imaging control unit of the CPU controls operations of the plurality of imaging units, the rotation mechanism, the radiation source elevating mechanism, and the detector elevating mechanism.

Abstract: A treatment instrument includes: a shaft; an end effector disposed on a distal side of the shaft; a joint connecting the end effector to a distal end of the shaft; a first part connected to a proximal side of the shaft and configured to bend the joint; wires each connecting the joint and the first part through the shaft and each configured to generate tension in response to an operation of the first part; and a second part connected to the proximal side of the shaft and configured to integrally rotate the shaft, the end effector, the joint, the first part, and the wires about a rotation axis passing through central axes of the shaft, the end effector, the joint, and the first part. The first part includes: a joystick displaceable in a direction intersecting a central axis of the shaft; and a lock fixing a position of the joystick.

Abstract: Provided is an endoscope system including an endoscope that images living tissue to be treated by at least one instrument; and a control device that includes a processor configured to derive at least one of the following information: grasp assistance information on a grasping operation to grasp the living tissue by the at least one instrument, and traction assistance information on a traction operation for traction of the living tissue by the at least one instrument, based on an endoscopic image acquired by the endoscope.

Abstract: An offer collecting system for a desired storehouse for keeping products and parts, includes a server connected with a network and having a storage section and a server display unit; a plurality of offerer terminals connected with the network; and an offer collection terminal connected with the server directly or through the network and having a terminal display unit. The offer collection terminal sets first and second collection condition sets in the storage section of the server. The server produces a storehouse offer collection display based on the first collection condition set to provide to the plurality of offerer terminals by displaying the storehouse offer collection display on the server display unit and stores offer data from each of the plurality of offerer terminals in the storage section.
