A system and method for patient positioning during radiotherapy. The system can include a patient support structure configured to receive a patient during a radiotherapy process using a radiotherapy source to deliver a therapy to the patient when positioned on the patient support structure, a patient positioning system configured to adjust a position of the patient support structure relative to the radiotherapy source, a flexible actuator configured to secure the patient to the patient support and adjust a position of the patient relative to the patient support, and an imaging system configured to acquire imaging data of the patient, the patient support, and the flexible actuator during the radiotherapy process.

A radiation detector includes a sensor panel unit, a support table to which the sensor panel unit is attached, and two fixing members. The sensor panel unit includes two sensor panels. The sensor panel has pixels that sense visible light converted from radiation and generate charge. The sensor panel unit has a configuration in which an end portion of one sensor panel and an end portion of the other sensor panel are arranged to overlap each other in a thickness direction. A first fixing member fixes two sensor panels in an overlap region in which the end portions overlap. A second fixing member fixes the sensor panel unit and the support table in the overlap region. The second fixing member at least partially overlaps the first fixing member in the overlap region in a plan view of the sensor panel unit in the thickness direction.

A radiation detector has a sensor panel unit which includes two sensor panels and in which end portions of the two sensor panels are arranged to overlap each other in a thickness direction. An image processing unit acquires two projection images from the two sensor panels. A combination unit of the image processing unit performs a process related to image quality on the projection image in a case in which a tomographic image which is a diagnosis image to be used for a doctor's diagnosis is generated and does not perform the process related to image quality on the projection image in a case in which a scout image which is a confirmation image for confirming a reflected state of the subject is generated.

Disclosed is a patient positioning assembly for orientating a patient with respect to a radiation source. The patient positioning assembly includes a translatable member movable in a vertical direction between a vertically downwards first position and a vertically upwards second position. The patient positioning assembly further includes a patient support assembly mounted to the translatable member and adapted to rotate relative to the translatable member about a vertical axis. The patient support assembly is configurable between a first orientation, which sustains the patient in a seated position, and a second orientation, which sustains the patient in a generally standing position.

A mobile medical imaging device that allows for multiple support structures, such as a tabletop or a seat, to be attached, and in which the imaging gantry is indexed to the patient by translating up and down the patient axis. In one embodiment, the imaging gantry can translate, rotate and/or tilt with respect to a support base, enabling imaging in multiple orientations, and can also rotate in-line with the support base to facilitate easy transport and/or storage of the device. The imaging device can be used in, for example, x-ray computed tomography (CT) and/or magnetic resonance imaging (MRI) applications.

A CT apparatus includes an annular frame that rotates around a subject positioned in a bore, three columns that hold the frame to be rotatable and movable up and down in a vertical, an elevation mechanism that moves up and down the frame, and a rotation mechanism that rotates the frame. A radiation source and a radiation detector are attached to the frame at positions facing each other. The frame has a width smaller than a width of the radiation source and the radiation detector in a height direction over a whole periphery. An imaging controller performs control for operating the elevation mechanism in response to a return instruction from an operator to move the frame to a retreat height position set at a position of a highest point in an elevation range of the frame on an upper end side of the columns. The imaging controller performs control for operating the rotation mechanism in response to the return instruction from the operator to rotate the frame to a position of 60° that is a first rotation position where the radiation source overlaps the columns.

Patient sitting equipment for radiotherapy, including an installation platform, a treatment couch assembly, a support and adjustment assembly and a 3D imaging assembly. The treatment couch assembly is configured to fix a patient. The support and adjustment assembly is configured to adjust a position of the treatment couch assembly with respect to the installation platform. The 3D imaging assembly includes a column assembly and a 3D imaging device. The column assembly is arranged at the installation platform, and extends along the vertical direction. The 3D imaging device is movably arranged at the column assembly, and is corresponding to the treatment couch assembly in a horizontal projection direction. The 3D imaging device is configured to scan the patient.

A CT apparatus includes a radiation source that emits radiation, a radiation detector that detects the radiation, an annular frame to which the radiation source and the radiation detector are attached and in which a subject is positioned in a bore, and three columns that hold the frame to be movable up and down in a vertical direction.

Provided is a 3D bone density and bone age calculation apparatus using an artificial intelligence-based rotation manner. The 3D bone density and bone age calculation apparatus includes a main body, and the main body includes a rotary drum including a drum shaft gear, an X-ray generator, an intensifying screen, and an image data capturer, a drum driver including a motor shaft gear connected to the drum shaft gear so as to rotate the rotary drum, a motor, support rollers and one of an origin sensor and an encoder, an outer case and an inner case, a front case and a rear case, a capturing holder, and a controller configured to select an image-captured position of the rotary drum, and configured to input a current age, sex and nutritional status of a patient, etc. The controller includes a display configured to display captured images and a diagram indicating bone age.
