Abstract: The accuracy charged-particle beam trajectories used for radiation therapy in patients is improved by providing feedback on the beam location within a patient's body or a quality assurance phantom. Particle beams impinge on a patient or phantom in an arrangement designed to deliver radiation dose to a tumor, while avoiding as much normal tissue as can be achieved. By placing fiducial markers in the tumor or phantom that contain specific atomic constituents, a detection signal consisting of atomic fluorescence is produced by the particle beam. An algorithm can combine the detected fluorescence signal with the known location of the fiducial markers to determine the location of the particle beam in the patient or phantom.

Abstract: The present document relates to providing a radiation treatment plan for treatment of a neoplasm, including the steps of: obtaining an image including the neoplasm and obtaining first segmentation data for segmenting at least one target-volume to be targeted with radiation. Further identifying any organs-at-risk and segmenting these. The method further comprises identifying lymphocyte-rich-organs in the image, and obtaining third segmentation data for segmenting the lymphocyte-rich-organs. The planning system then obtains radiation dose regime data, including first, second and third dose regime data. The planning system then determines a radiation treatment plan which provides treatment process parameters for operating one or more radiation beams for radiation treatment of the neoplasm, The process parameters are determined to apply the radiation at a first radiation dose to the target volume which corresponds with the first dose regime data, apply the radiation at a minimized second radiation dose to the or each organs-at-risk, and apply the radiation at a third radiation dose to the or each lymphocyte-rich-organ which corresponds with the third dose regime data, wherein the third radiation dose amount is minimized.

Abstract: Disclosed herein are systems and methods for monitoring calibration of positron emission tomography (PET) systems. In some variations, the systems include an imaging assembly having a gantry comprising a plurality of positron emission detectors. A housing may be coupled to the gantry, and the housing may include a bore and a radiation source holder spaced away from a patient scan region within the bore. A processor may be configured to receive positron emission data from the positron emission detectors and to distinguish the positron emission data from the radiation source holder and from the patient scan region. A fault signal may be generated when the positron emission data from the radiation source holder exceeds one or more threshold parameters or criteria.

Abstract: Embodiments are directed generally to an ionizing-radiation beamline monitoring system that includes a vacuum chamber structure with vacuum compatible flanges through which an incident ionizing-radiation beam enters the monitoring system. Embodiments further include at least one scintillator within the vacuum chamber structure that can be at least partially translated in the ionizing-radiation beam while oriented at an angle greater than 10 degrees to a normal of the incident ionizing-radiation beam, a machine vision camera coupled to a light-tight structure at atmospheric/ambient pressure that is attached to the vacuum chamber structure by a flange attached to a vacuum-tight viewport window with the camera and lens optical axis oriented at an angle of less than 80 degrees with respect to a normal of the scintillator, and at least one ultraviolet (“UV”) illumination source facing the scintillator in the ionizing-radiation beam for monitoring a scintillator stability comprising scintillator radiation damage.

Abstract: The present disclosure provides a neutron capture therapy system, including an accelerator for generating a charged particle beam, a neutron generator for generating a neutron beam having neutrons after irradiation by the charged particle beam, and a beam shaping assembly for shaping the neutron beam. The beam shaping assembly includes a moderator and a reflecting assembly surrounding the moderator. The neutron generator generates the neutrons after irradiation by the charged particle beam. The moderator moderates the neutrons generated by the neutron generator to a preset energy spectrum. The reflecting assembly includes a reflecting assembly to deflected neutrons back to the neutron beam and a supporting member to support the reflectors. A lead-antimony alloy is for the reflecting assembly to mitigate a creep effect that occurs when only a lead material is for the reflectors, thereby improving the structural strength of a beam shaping assembly.

Abstract: A method provides real-time correction of the spatial position of the central beam of radiation therapy devices and therapy simulators, along with the patient position. In particular, the method relates to the real-time correction of irradiation positions of the collimator and/or the position of the patient positioning table during the performance of radiation therapy or therapy simulation. Positional deviations of the central beam of existing radiation therapy devices are reduced. Position adjustments of the collimator elements and/or of the patient support table are carried out through functional connections of separate control modules via separate adjustment devices. Those are added to the collimator and/or patient support table. Calculation of the correction movements takes place outside the radiation therapy device in the irradiation planning system and/or in at least one microcontroller of the control system of the radiation therapy device.

Abstract: 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.
