It is an object of the invention to address the above mentioned issues related to image quality and patient positioning. This object is achieved by a mock-up antenna configured to be used during radiation treatment delivery, wherein the radiation treatment is delivered based on a radiation treatment plan and wherein the radiation treatment plan is at least partly based on a planning magnetic resonance image. The mock-up antenna is substantially transparent to radiation and comprises connection means configured to allow a connection between the mock up antenna and a fixation means, which fixation means is configured to fixate a position of the mock-up antenna during radiation treatment and. The mock-up antenna further comprises an inner surface configured to be positioned towards a patient in a way such that is affects a position and/or orientation of the patient during radiation treatment delivery, wherein the inner surface has a shape substantially similar to a shape of a working magnetic resonance imaging antenna used during an acquisition of the planning magnetic resonance image.

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.

The disclosure relates to a robot, for example for patient positioning, comprising a robot arm with a plurality of robot elements, which are connected to one another by means of shaft units. The shaft units define a respective at least one movement axis of the robot arm. The robot arm comprises a first end region, which permits an arrangement in a surrounding area of the robot, and a second end region, on which an end effector can be arranged. A first shaft unit arranged after the first end region defines a first rotational axis of the robot arm. The robot arm can be arranged in the surrounding area by means of the first end region in such a way that the first rotational axis runs at an angle transverse to the surrounding area.

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.

Visualizing a deformation amount or displacement amount of a region of interest in therapy rendered in an image upon aligning images used in radiation therapy allows for enhancing an accuracy of alignment. In a positioning system 104, an image processing unit 201 calculates a deformation parameter using a non-rigid registration method for a region of interest having been set by a treatment planning device 101 based on a treatment plan CT image and three-dimensional tomographic image imaged for bed positioning and calculates a displacement amount parameter for a region extracted using a region extraction method. The image processing unit 201 calculates a positioning parameter representing a displacement amount of a bed based on the calculated deformation parameter and displacement amount parameter and displays the respective parameters together with an alignment image, thereby allowing for confirmation of the deformation amount and displacement amount.

A radiation therapy apparatus that enhances the reliability and ease of use of a treatment is provided. A radiation therapy apparatus includes: a treatment bed moving a top plate with an object to be treated Pt placed on the top plate to a predetermined treatment location; an imaging apparatus moving to the predetermined treatment location from a direction different from the direction of movement of the top plate and picking up an image of the object to be treated; and an irradiation apparatus provided between the treatment bed and the imaging apparatus, extensible, and applying a radioactive ray to the object to be treated. When the CT apparatus moves to the treatment location, the irradiation apparatus moves to a predetermined waiting position P1. When applying a radioactive ray to an object to be treated, the irradiation apparatus moves to a predetermined irradiation position P3.

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.
