A medical support apparatus comprising a processor configured to: acquire a surgical field image obtained by optically taking, with a camera, an image of a surgical field containing a target area inside the body; generate a composite image with preparation information superimposed onto the surgical field image, the preparation information having been prepared in advance as information related to the target area, including at least a three-dimensional image illustrating an internal structure of the target area or applied information applied to the three-dimensional image, and having a defined three-dimensional position within the three-dimensional image; and control displaying of the composite image, wherein if the preparation information further includes a plurality of pieces of preparation information at different depths in a depth direction proceeding from a surface layer to deep layers of the target area in the three-dimensional image, the processor is configured to change a display appearance of the plurality of pieces of preparation information in the composite image, depending on the depth.

Provided are an image processing apparatus, an operation method of the image processing apparatus, and an operation program of the image processing apparatus that can perform registration of an ultrasound image (13) and a three-dimensional image such that a registration result does not fall into a local solution and a clearly incorrect registration result is not output.An acquisition unit acquires a CT image of a patient. A generation unit acquires a US image of the patient by generating the US image from an echo signal. A selection unit repeatedly selects a plurality of reference points from a first point group of the US image and a plurality of target points from a second point group of the CT image a plurality of times. A derivation unit derives a candidate parameter each time the reference point and the target point are selected. A determination unit determines whether the candidate parameter satisfies a constraint condition related to a position and a posture of an ultrasound probe (10) at the time of capturing the US image.

In order to support imaging of a radiographic imaging apparatus including a radiation source that emits radiation, and an optical camera (21) that is mounted on the radiation source and that captures an optical image (G1) of a subject in a direction from the radiation source, a processor (41) derives a relative angle between the radiation source and a target plane; and displays the optical image (G1) and an angle indicator representing the relative angle and a target angle on a display (25) mounted on the radiation source.

Provided are a medical imaging apparatus, a medical imaging support method, and a program that can notify a user of a plurality of notifications from a subject. A medical imaging apparatus according to the present disclosure captures a medical image of a subject, identifies a first motion performed by the subject inserted into a bore of a gantry based on information acquired by a motion sensor, compares the identified first motion with a plurality of second motions registered in a memory, and notifies the user of notification content corresponding to the second motion that matches the identified first motion among the plurality of second motions registered in the memory.

An object is to receive designation of a two-dimensional position on an ultrasound image and enable control of an ultrasound diagnostic apparatus in accordance with the designated position.A display unit receives designation of a point on a displayed ultrasound image by a touch operation or the like. A positional information conversion unit converts coordinates of the point expressed in a coordinate system of the ultrasound image into coordinates in a coordinate system used by an ultrasound diagnostic apparatus for ultrasound beam scanning. A central controller and a control position setting unit control the ultrasound diagnostic apparatus (for example, setting an ROI) using the coordinates obtained by the coordinate conversion.

A lithographic printing plate precursor including a support and an image-recording layer on the support, in which the image-recording layer contains a polymer A having a main chain containing two or more silicon atoms, and a hydrophilic group.

Attachment of a biopsy needle guiding adapter to an ultrasound probe can be easily performed outside an abdominal cavity, and an attachment state of the biopsy needle guiding adapter in the abdominal cavity can be easily checked. Alternatively, smooth insertion and removal of the ultrasound probe from a guide tube passing through an abdominal wall can be performed. A puncture adapter is attachably and detachably mounted on a head part of a probe outside an abdominal cavity. The puncture adapter has a body part that covers a through-hole guiding a biopsy needle, an insertion part that is inserted into the through-hole, and a needle guide hole that communicates with the body part and the insertion part and that guides the biopsy needle inserted from a needle entrance portion in the body part to a needle entrance portion in the insertion part.

Provided is an X-ray imaging apparatus having a relatively simple structure, in which a state in which an X-ray tube and an FPD face each other can be reliably ensured. An X-ray imaging apparatus (1) includes an X-ray tube (12) that emits X-rays, a drive mechanism (11) that moves the X-ray tube (12) in each of three axial directions, an imaging stand that stores an X-ray detector (40) and on which a subject is placed, and a processor (70) that controls imaging in accordance with an instruction from an operator via an operation panel. The processor (70) acquires position information of the X-ray tube (12) from sensors that detect movement of the X-ray tube (12) in the three axial directions, and displays, on the operation panel or a display device, a relative position of the X-ray tube (12) with respect to the X-ray detector (40) in the form of an indicator.

An object is to extend a replacement lifetime of a cryocooler and reduce a replacement frequency of the cryocooler, thereby improving an operating rate of an MRI apparatus. A cold head lifetime extension mode is executed. In the cold head lifetime extension mode, a displacer of a cryocooler is driven at a constant frequency that is lower than a predetermined upper limit frequency regardless of a temperature of a superconducting coil, and a drive frequency of a compressor drive unit adjusted by an inverter for a compressor is controlled in accordance with the temperature of the superconducting coil.

An object is to extend a replacement lifetime of a cryocooler (70) and reduce a replacement frequency of the cryocooler, thereby improving an operating rate of an MRI apparatus (1).A processor (20) has an imaging mode and a non-imaging mode. In the imaging mode, a displacer is caused to operate continuously at a constant frequency regardless of a pressure in a vessel of a superconducting magnet (101).
