A framework for characterization of a collimator. In accordance with one aspect, first and second sides of the collimator are photographed to generate first and second image data. An optical characterization map (OCM) may be generated based on the first and second image data, wherein the optical characterization map characterizes the individual channels of the collimator. Quality assessment or image reconstruction may then be performed based on the OCM.

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 bed capable of reducing a burden of posture conversion of a subject. There is provided a bed on which a subject is placed including: an upper body-holding bed configured to rotate around a rotational axis extending along a central axis of the subject, and to hold and rotate the upper body of the subject; and a lower body-holding bed configured to rotate around the rotational axis, and to hold and rotate the lower body of the subject, wherein the upper body-holding bed and the lower body-holding bed are configured so that one of these components rotates in accordance with rotation of the other.

An apparatus includes a body, an upright member, a frame, and a plurality of field generating elements. The body is configured to be positioned between a patient's back and a backrest of a chair. The upright member extends upwardly from the body. The frame has a curved configuration configured to partially surround a patient's head. The field generating elements are configured to generate an electromagnetic field around a patient's head partially surrounded by the frame.

An X-ray image diagnostic apparatus is provided with a top board, a movable X-ray source, an X-ray detection unit, a storage unit, an X-ray source drive unit, and a registered position operation part for performing an operation of moving the ray source to a registered position by the registered position drive unit. The X-ray image diagnostic apparatus is configured not to include an arbitrary position operation part for performing an operation of moving the X-ray source to an arbitrary position by the X-ray source drive unit.

An X-ray photography apparatus including: a turning arm that supports an X-ray generator and an X-ray detector which are opposed to each other so that the head of a patient can be interposed therebetween, and a moving mechanism that includes a turning part and a moving part. The turning part turns the turning arm about a turning axis with respect to the head. The moving part moves the turning arm relative to the head in a direction perpendicular to the turning axis. The X-ray photography apparatus also includes: an image processor that generates an X-ray image, a photographic region designation part that designates part of a row of teeth along a dental arch as a pseudo intraoral radiography region, and an X-ray forming mechanism that changes the irradiation direction in which the head is irradiated with an X-ray relative to the axial direction of the body axis of the patient.

The present invention relates to a device (1) for determining positioning data for an X-ray image acquisition device (2) on a mobile patient support unit (3), the device comprising: a processing unit (10); and a status detector (11); wherein the status detector (11) is configured to acquire geometry data and type data of a mobile patient support unit (3) and of an X-ray image acquisition device (2) on the mobile patient support unit (3), and to transmit a status signal comprising the geometry data and the type data; wherein the processing unit (10) is configured to receive the status signal and data about region of interest position on the patient; and wherein, based on the status signal and the region of interest position, the processing unit (10) is configured to determine positioning and alignment data for an X-ray image acquisition device (2) on the mobile patient support unit (3), and to provide an image acquisition protocol for the X-ray image acquisition device (2). The device (1) may provide an X-ray image acquisition system having a simple and easy to operate construction.

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, outer and inner cases, front and rear cases, a capturing holder, and a controller including a position selector configured to select an image-captured position of the rotary drum, an input unit configured to input a current age, sex and nutritional status of a patient, etc., and a display configured to display captured images and a diagram indicating bone age.

An X-ray dental imaging system for medical imaging includes a column, a housing coupled to the column, and a lower shelf movably coupled to at least one of the column or the housing.

A system includes a first radiation source configured to provide therapeutic radiation in a treatment area and an automated patient transport configured to transport a patient from a preparation area to the treatment area, to position a treatment volume in the patient relative to the therapeutic radiation from the first radiation source, and to support the patient in receiving the therapeutic radiation. The automated patient transport comprises a first detector configured to detect a first patient positioning indicator located in and/or on the patient indicative of a position of the treatment volume.
