A radiation therapy system includes an X-ray imaging system that is configured with a combined and simplified filter and collimator positioning mechanism. In addition, an X-ray imager of the RT system is only positioned at a few discrete locations within a plane that is a fixed distance from the imaging X-ray source when generating X-ray images. As a result, for each of these discrete imaging positions, the simplified filter and collimator positioning mechanism positions a specific collimator-filter combination in a specific location between the X-ray source and the imager.

The present application relates to systems and methods used to characterize or verify the accuracy of a tracker comprising optically detectable features. The tracker may be used in spatial localization using an optical sensor. Characterization results in the calculation of a Tracker Definition that includes geometrical characteristics of the tracker. Verification results in an assessment of accuracy of a tracker against an existing Tracker Definition.

A transport apparatus may include a patient bed unit for supporting the patient; a transferring unit for moving the patient bed unit along a first direction of the MRI device; and an elevating module for moving the patient bed unit along a second direction of the MRI device.

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.

Example methods and apparatuses of controlling a user interface with a plurality of input mechanisms are disclosed. One example method includes causing a first set of input mechanisms in the plurality of input mechanisms to be visually emphasized via a first visual technique while a second set of input mechanisms in the plurality of input mechanisms is not visually emphasized via the first visual technique, receiving a user input via an input mechanism that is included in the first set, based on the user input, determining a third set of input mechanisms in the plurality of input mechanisms and a fourth set of input mechanisms in the plurality of input mechanisms, and causing the third set of input mechanisms to be visually emphasized via the first visual technique while the fourth set of available input mechanisms is not visually emphasized via the first visual technique.

Provided herein is technology relating to medical imaging and radiation therapy and particularly, but not exclusively, to devices, methods, and systems for positioning a patient with respect to a radiation source to image the patient and/or to treat the patient by exposing the patient to a radiation beam produced by the radiation source.

The disclosure relates to a system and method for medical imaging. The method may include: move, by a motion controller, a phantom along an axis of a scanner to a plurality of phantom positions; acquire, by a scanner of the imaging device, a first set of PET data relating to the phantom at the plurality of phantom positions; and store the first set of PET data as an electrical file. The length of an axis of the phantom may be shorter than the length of an axis of the scanner, and at least one of the plurality of phantom positions may be inside a bore of the scanner.

A method of providing imaging of a patient supported by a patient support platform arranged to be rotated about a first patient rotation axis by a patient rotation angle, the method constituted of: rotating an imager about an imager rotation axis by the patient rotation angle; translating the imager along a first imager translation axis; and translating the imager along a second imager translation axis different than the first imager translation axis, wherein responsive to the translation of the imager along the first imager translation axis and along the second imager translation axis, the imager is translated along an imaging axis defined by the patient support platform such that the imager is arranged to image the patient supported by the patient support platform.

A patient support apparatus has a movable patient couch, a support unit, and a coupling unit for coupling with a detector unit of a medical imaging apparatus, wherein the patient support apparatus has a damping unit that is designed to damp and/or compensate forces which act on the patient support apparatus coupled with the detector unit.

An X-ray computed-tomography (CT) apparatus according to an embodiment includes an X-ray tube, a detector, a table top, and processing circuitry. The X-ray tube generates an X-ray. The detector detects the X-ray. On the table top, a subject is placed. The processing circuitry controls a moving mechanism to move the table top in a longitudinal direction. The processing circuitry displays information indicating magnitude of a vibration that occurs, when each position in the longitudinal direction on the table top is moved to a position intersecting a path of the X-ray, at the position.
