A data acquisition device, which has an X-ray detector including a plurality of channel widths at which channels at its central portion are fine and channels at its peripheral portions are coarse or rough, and a plurality of data acquisition ranges including a data acquisition range wide in a channel direction and a data acquisition range narrow in the channel direction, and which is capable of performing switching among the data acquisition ranges for each data acquisition, is used to perform data acquisition on the channels fine at the central portion in the data acquisition range narrow in the channel direction, whereby an X-ray CT apparatus is provided which is capable of performing high-resolution imaging and brings about more satisfactory image quality.

X-ray ct apparatus

A compact sensor module and methods for forming the same are disclosed herein. In some embodiments, a sensor die is mounted on a sensor substrate. A processor die can be mounted on a flexible processor substrate. In some arrangements, a thermally insulating stiffener can be disposed between the sensor substrate and the flexible processor substrate. At least one end portion of the flexible processor substrate can be bent around an edge of the stiffener to electrically couple to the sensor substrate

Compact sensor module

An endoscope washing and disinfecting apparatus (1) includes: a connecting portion (30) connected to a bending transmitting portion (55) of an endoscope (50) to transmit driving force; a distal end driving portion for transmitting the driving force to the bending transmitting portion (55) through the connecting portion (30); a fluid supplying unit for supplying gas into an inner space of the endoscope (50); and a control unit (102) for controlling a pressure detecting portion (105) for detecting pressure in the inner space and the distal end driving portion (104/21) to provide the bending portion (54) with bending motion, and for determining occurrence or nonoccurrence of water leak in the endoscope (50) by comparing the pressure detected by the pressure detecting portion (105) and a preset threshold.

A radiation image capturing device includes: an image capturing unit that captures a radiation image using irradiated radiation; a radiation detection unit that detects the radiation; a determination unit that determines whether image capturing preparation is completed; and a control unit that starts detection of the radiation by the radiation detection unit, in a case in which the determination unit determines that the image capturing preparation is completed, and controls the image capturing unit to capture a radiation image, in a case in which the radiation detection unit detects the radiation.

Radiation image capturing device and radiation image capturing method

In an apparatus without a helical movement, a reconstruction error considerably increases as a radiation angle increases. In a prior art embodiment, for example, a one-side value of the radiation angle is 9.5 degrees, and it is predicted that the reconstruction error at its periphery considerably increases. In a radiation imaging apparatus including a radiation generating source for radiating radiation to a subject, a rotating unit for rotating the subject exposed to the radiation from the radiation generating source, and a two-dimensional detector for detecting radiation, a distance between the radiation generating source and the two-dimensional detector is approximately set to a value equal to or more than 240 cm.

Radiation imaging apparatus

A radiation image capturing apparatus includes a housing for housing a radiation detector The housing has a wall inclined with respect to a detection surface of the radiation detector, and the wall defines a space inclined with respect to the detection surface The space allows heat transfer medium such as air of relatively high temperatures (higher than that of outside air, for example) to rise along a slope defined by the space If the region around the detection surface is heated to high temperatures, airflow is generated within the space, forcing the relatively high-temperature heat transfer medium away from the vicinity of the radiation detector, thereby allowing the whole radiation detector to be cooled in a uniform manner

Radiation image capturing apparatus

An image detecting device includes an image detector, a temperature regulation controller, an image information output detector, and a timer, wherein the temperature regulation controller stops or relaxes the temperature regulation control operation on the image detector based on the image information output detection signal input thereto from the image information output detector, and resumes or stops relaxing the temperature regulation control operation on the image detector when the timer has measured a preset period of time after the temperature regulation control operation has been stopped or relaxed.

A medical fixed balloon disposed in an insertion portion to be inserted into a body cavity so as to fix the insertion portion to the inside of the body cavity, comprising:
 an inflation membrane inflated by supplying a fluid into an inside of the inflation membrane and whose outer peripheral surface is brought into contact with an inner wall of the body cavity, the inflation membrane having regions extended with a predetermined extension rate and having a plurality of low extension regions of a lower extension rate than the predetermined extension rate, formed on a line segment from a base end to a distal end along an insertion axis of the insertion portion

Medical fixed balloon, actuator for intraductal moving body, and endoscope

The method is a method of rinsing an endoscope in an endoscope cleaner placed in a vessel. The method includes a step of charging a surfactant into a vessel in addition to water to fill the vessel with a first rinse water containing the surfactant, a step of rinsing the endoscope placed in the vessel with the first rinse water, a step of supplying only water into the vessel after rinsing with the first rinse water to fill the vessel with a second rinse water that does not contain the surfactant and a step of rinsing the endoscope with the second rinse water. In the method, the action of the surfactant contained in the detergent is effectively utilized in a rinsing treatment of the endoscope while the endoscope is rinsed to thereby ensure that re-deposition of dirt is suppressed to enhance the overall cleaning efficiency.

Method of rinsing endoscopes

An aspect of the actuator for the moving body in tube according to the present invention is characterized by including: a first expansion/contraction member which includes a first portion that fills between the moving body in tube and the tube wall at the time of being expanded to come into contact with the tube wall, and a second portion that is brought into contact with the tube wall to generate propulsive force, and a part of which is fixed to the moving body in tube; a drive device which drives the first expansion/contraction member; and a control section which controls the first expansion/contraction member and the drive device, and is characterized in that the control section performs control so that the first portion of the first expansion/contraction member is made to become the second portion by the drive by the drive device so as to change the relative position between the moving body in tube and the tube wall.
