Neutron capture therapy system and therapy planning system for neutron capture therapy
A neutron capture therapy system includes a therapy table on which an irradiation target is placed, a neutron beam irradiation unit which irradiates the irradiation target placed on the therapy table with a neutron beam, a position measurement unit which measures a position of the irradiation target placed on the therapy table, and a radiation dose distribution output unit which outputs a radiation dose distribution of a neutron beam used for irradiating the irradiation target, based on an amount of positional misalignment of the position of the irradiation target measured by the position measurement unit.
DOSE EVALUATION SYSTEM, PLANNING SYSTEM, PARTICLE IRRADIATION SYSTEM AND DOSE EVALUATION METHOD
A function/process of recording marker position data and spot data is provided. The marker position data includes position information of a marker 29 measured for tumor tracking irradiation and information on time of execution of X-ray imaging. The spot data includes information on time of irradiation of each spot, a delivered irradiation position, and a delivered irradiation amount. The marker position data and the spot data are synchronized based on the time information, and by using the marker position data and the spot data upon spot irradiation, a delivered dose distribution of proton irradiation is calculated. With this configuration, it is possible to take the influence of interplay effect into consideration, and it is possible to support to make more appropriate determination upon replanning of a treatment plan.
DEVICES AND METHODS FOR ADAPTIVELY CONTROLLING A RADIOTHERAPY APPARATUS
Methods, systems and computer-readable media for controlling a radiotherapy apparatus are disclosed. A method for controlling a radiotherapy apparatus comprises obtaining a first treatment plan comprising positioning information of a beam shaping apparatus of the radiotherapy apparatus; receiving, during delivery of a radiation therapeutic beam to a target on a patient, information including a positional shift of the target; and generating a revised treatment plan based on the first treatment plan, the generating of the revised treatment plan comprising determining an updated configuration of the beam shaping apparatus from the positioning information of the first treatment plan based on the positional shift of the target.
BLOOD-TISSUE SURFACE BASED RADIOSURGICAL RENAL TREATMENT PLANNING
Devices, systems, and methods for planning radiosurgical treatments for neuromodulating a portion of the renovascular system may be used to plan radiosurgical neuromodulation treatments for conditions or disease associated with elevated central sympathetic drive. The renal nerves may be located and targeted at the level of the ganglion and/or at postganglionic positions, as well as preganglionic positions. Target regions include the renal plexus, celiac ganglion, the superior mesenteric ganglion, the aorticorenal ganglion and the aortic plexus. Planning of radiosurgical treatments will optionally employ a graphical representation of a blood/tissue interface adjacent these targets.
BEAM STATION TREATMENT PLANNING AND RADIATION DELIVERY METHODS
Described herein are methods for beam station delivery of radiation treatment, where the patient platform is moved to a series of discrete patient platform locations or beam stations that are determined during treatment planning, stopped at each of these locations while the radiation source rotates about the patient delivering radiation to the target regions that intersect the radiation beam path, and then moving to the next location after the prescribed dose of radiation (e.g., in accordance with a calculated fluence map) for that location has been delivered to the patient.
METHODS AND APPARATUS FOR CONTROLLING TREATMENT DELIVERY USING REINFORCEMENT LEARNING
Methods and systems are provided which relate to the planning and delivery of radiation treatments by modalities which involve moving a radiation source along a trajectory relative to a subject while delivering radiation to the subject. An artificial intelligence (AI) agent trained using reinforcement learning (and/or some other suitable form of machine learning) is used to control the radiation delivery parameters in effort to achieve desired delivery of radiation therapy. In some embodiments, the AI agent selects suitable control steps (e.g. radiation delivery parameters for particular time steps), while accounting for patient motions, difference(s) in patient anatomical geometry and/or the like.
Bore based medical system comprising a camera carrier configured to be mounted in the bore-based medical systems and utilized for positioning and monitoring of patients during radiotherapy treatment
Disclosed is a bore based medical system comprising a camera carrier configured to be mounted in the bore based medical system and configured to monitor and/or track patient motion within said bore based medical system during radiotherapy, the bore based medical system comprising a rotatable ring-gantry configured to emit a radiotherapy beam focused at an iso-center of the bore based medical system, wherein the ring-gantry is configured to rotate at least partly around a through-going bore having a front side and a back side, configured to receive from said front side, a movable couch configured to be moved into and out from the through-going bore, wherein further the through-going bore comprises an inner side facing an inside of the bore, and wherein the camera carrier is configured to be mounted inside the bore in connection with the inner side of the through-going bore.
Research and development of augmented reality in radiotherapy
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.
METHOD AND APPARATUS FOR EMISSION GUIDED RADIATION THERAPY
An apparatus comprising a radiation source, coincident positron emission detectors configured to detect coincident positron annihilation emissions originating within a coordinate system, and a controller coupled to the radiation source and the coincident position emission detectors, the controller configured to identify coincident positron annihilation emission paths intersecting one or more volumes in the coordinate system and align the radiation source along an identified coincident positron annihilation emission path.
