The second switch is configured to include a first state and a second state, wherein the first state is a state in which the superconducting coil and the any one of the external power supply, the load, or both the external power supply and the load are electrically connected to each other, and the second state is a state in which electrical connection between the superconducting coil and the any one of the external power supply, the load, or both the external power supply and the load is cut off. The control apparatus is configured to switch the second switch between the first state and the second state.

An X-ray CT apparatus (200) according to an embodiment includes an X-ray detector (12) and processing circuitry (150). The X-ray detector (12) detects X-rays emitted from an X-ray tube and transmitted through a subject. The processing circuitry (150) generates input data(50) based on data obtained from the X-ray detector (12), when executing inference on a trained model, obtains a feature value from the trained model with respect to a region of interest set based on the input data(50), based on the obtained feature value, determines whether or not to continue the inference with respect to the regions of interest, and stops the inference on determining not to continue the inference and continue the inference on determining to continue the inference.

An X-ray CT apparatus (1) according to an embodiment includes a scanner unit (20), a support unit (103), a detection unit (56), a detection control unit (55), and an operation control unit (51). The scanner unit has an imaging system. The support unit supports the scanner unit and moves the scanner unit in the vertical direction. The detection unit defines at least part of an area between an outer periphery of an opening into which a subject is inserted and the subject as a detection area and detect an object present in the detection area. The detection control unit performs control to define an area in which the movement of the subject is restricted as a non-detection area. The operation control unit stops the operation of the scanner unit when it is detected that the object is present in the detection area excluding the non-detection area.

A motion compensation apparatus according to an embodiment, includes an acquisition unit (110), a determination unit (120), a first reconstruction unit (120), a estimation unit (130) and a second reconstruction unit (140). The acquisition unit (110) acquires projection data scanned from an imaging object by the computed tomography imaging system. The determination unit (120) determines a target time point for which a motion-corrected image of the imaging object is to be reconstructed. The first reconstruction unit (120) reconstructs first and second groups of feature-enhanced partial images, based on, respectively, first and second sets of the projection data, the first and second sets of the projection data being on opposite sides of the target time point. The estimation unit (130) is configured to estimate a motion vector field for the target time point, based on the first and second groups of feature-enhanced partial images. The second reconstruction unit (140) is configured to perform, based on the motion vector field, motion compensation on the projection data to reconstruct an image of the imaging object, as the motion-corrected image for the target time point.

According to one embodiment, an automatic analyzer includes a cell, a plurality of holders, and a temperature-controlled bath. The cell contais a reaction liquid. The plurality of holders hold the cell and includes a housing provided with an insertion hole into which the cell is inserted. The housing includes a groove in which a bottom surface is formed such that an edge of an opening of the cell inserted into the insertion hole protrudes from the bottom surface in which an opening of the insertion hole is formed. The temperature-controlled bath accommodates the plurality of holders such that part of each of the holders is immersed in a temperature-controlled liquid.

A magnetic resonance imaging apparatus (100) according to an embodiment includes a processing circuit (150). The processing circuit (150) generates a first sensitivity map (11) based on magnetic resonance data (10), generates a first reconstructed image (12) by performing reconstruction based on the first sensitivity map (11), generates a second sensitivity map (13) based on the first reconstructed image (12) and the first sensitivity map (11), and generates a second reconstructed image (14) by reconstructing the magnetic resonance data (10) based on the second sensitivity map (13).

An ultrasonic diagnostic apparatus according to an embodiment includes a first acquisition unit, a second acquisition unit, and a generation unit. The first acquisition unit acquires a first image on which surface rendering has been executed on three-dimensional ultrasonic data related to a subject. The second acquisition unit acquires a light attenuation coefficient corresponding to the three-dimensional ultrasonic data. The generation unit generates a rendering image based on the first image and the light attenuation coefficient.

According to one embodiment, an adapter is attached to a reagent container used in an automatic analyzing apparatus, is contained in a reagent storage in the automatic analyzing apparatus together with the reagent container to which the adapter is attached, and the adapter includes a main body and a held portion. The main body includes a first opening portion and a second opening portion. The first opening portion is configured such that the reagent container can be attached and detached through the first opening portion. The second opening portion brings air in the reagent storage in contact with the reagent container at a time when the reagent container is contained in the reagent storage. The held portion is provided on the main body and held by a transfer mechanism that the automatic analyzing apparatus includes.

An automatic analyzing apparatus according to an embodiment includes an installation table, a transporter, an acquisition unit, and a control unit. The installation table is for installing a specimen rack that holds a specimen container for containing a specimen and a reagent container for containing a reagent used for measurement.
