The invention provides a patient shuttle system and an irradiation system for particle therapy. A patient shuttle system of one embodiment of the invention includes: a patient table (110) adapted to carry a patient; a patient table drive unit (120) that moves and/or rotates the patient table; and a transfer unit (130) having a base (131) on which the patient table drive unit is placed. In a home position state of the patient shuttle system (100), the patient table and first and second arms of the patient table drive unit are configured to be folded in the height direction (Z-axis). A robot arm base connected to the second arm is fixed at a position off the center of the base in plan view, and thereby a helper space (135) where a helper may ride is secured on the base. The robot arm base is fixed in a recess (138) provided in the base.

Provided is an operation procedure of a positioning device of a radiation therapy system. The radiation therapy system includes a radiation generation device used to generate therapeutic radiation, an irradiation chamber used to accommodate an irradiation subject receiving the radiation, a management chamber used to achieve irradiation control, and a support device used to transport and support the irradiation subject. The support device includes a support member supporting the irradiation subject, an adjustment assembly for adjusting a spatial position of the support member, and a joining assembly fixedly connecting the support member and the adjustment assembly together in a detachable manner. The support member at least includes a first support member and a second support member having a different size and/or shape from the first support member. The invention allows switching between support members having different sizes and/or shapes according to an actual use requirement.

Subject positioning systems and methods are provided. A method may include obtaining first information of at least part of a subject when the subject is located at a preset position, and determining, based on the first information, a first position of each of one or more feature points located on the at least part of the subject. The method may include obtaining, using an imaging device, second information of the at least part of the subject when the subject is located at a candidate position. The method may further include determining, based on the second information, a second position of each of the one or more feature points, a first distance between the first position and the second position for each feature point of the one or more feature points, and a target position of the subject based at least in part on the one or more first distances.

An example particle therapy system includes a gantry having a beamline structure configured to direct a particle beam that is monoenergetic from an output of a particle accelerator towards an irradiation target, where the beamline structure includes magnetic bending elements to bend the particle beam along a length of the beamline structure; and an energy degrader downstream of the beamline structure relative to the particle accelerator, where the energy degrader is configured and controllable to change an energy of the particle beam prior to at least part of the particle beam reaching the irradiation target.

Some embodiments are directed to an image director of a patient monitoring system to obtain calibration images of a calibration sheet or other calibration object at various orientations and locations. The images are then stored and processed to calculate camera parameters defining the location and orientation of the image detector and identifying internal characteristics of the image detector, and the information are stored. The patient monitoring system can be re-calibrated by using the image detector to obtain an additional image of a calibration sheet or calibration object. The additional image and the stored camera parameters are then used to detect any apparent change in the internal characteristics of the image detector (10) (S6-4).

A motion compensation system for tracking and compensating for patient motion during a medical imaging scan comprises an optical marker comprising an optically visible pattern and a mounting portion; a first optical detector positioned to digitally image the optically visible pattern along a first line of sight; a second optical detector positioned to digitally image the optically visible pattern along a second line of sight; a tracking engine configured to determine a pose of the object in six degrees of freedom by analyzing images from the first and second optical detectors; and a controller interface configured to generate tracking information based on the pose and to electronically transmit the tracking information to a scanner controller to enable compensation within a medical imaging scanner for object motion.

The present disclosure relates to a patient motion tracking system for automatic generation of a region of interest on a 3D surface of a patient positioned in a radiotherapy treatment room. More particularly, the disclosure relates to an assistive approach of a motion tracking system, by which a region of interest (ROI) is automatically generated on a generated 3D surface of the patient. Furthermore, a method for automatically generating a ROI on the 3D surface of the patient is described. In particular, all the embodiments refer to systems integrating methods for automatic ROI generation in a radiotherapy treatment setup.

First and second skeleton model data is determined based on first and second surface data of a patient. Each of the skeleton model data describes geometries of rigid anatomic structures of a patient at a different point in time. Skeleton difference data is determined describing differences between the geometries of the rigid anatomic structures. In a next step, movement instruction data is determined which describes movement to be performed by the rigid anatomic structures to minimize the differences, i.e. to correct the posture of the patient. The movement instruction data is for example determined based on anatomy constraint data which describes anatomical movement constraints for the rigid anatomic structures (e.g. range of motion of a joint). An instruction is displayed (e.g. using augmented reality), guiding the user how to move the rigid anatomic structures so as to correct the patient's posture.

A method is provided of producing an optical filter. The method comprises depositing a first mirror layer onto a substrate; depositing an insulating layer on the first mirror; exposing at least some of a plurality of portions of a surface of the insulating layer to a dose of energy; developing the insulating layer in order to remove a volume from the at least some of the plurality of portions of the insulating layer, wherein the volume of the insulating layer removed from each portion. is related to the dose of energy exposed to each portion, and wherein a remaining thickness after the removal of the volume from each portion of the insulating layer is related to the dose of energy exposed to each portion. The method further comprising depositing a second mirror layer on the remaining thickness of each of the plurality of portions of the insulating layer.

An apparatus for use with a medical system, the medical system comprising a medical device configured to treat and/or image a patient, includes: a camera configured to capture an image of a first mirror, wherein the image of the first mirror contains an image of at least a part of the patient and/or an image of at least a part of the medical system; wherein the camera comprises electronics that are not radiation-hard.
