    摘要: A system and method are provided for imaging and treatment of tumorous tissue in a patient. In an embodiment, the system includes a radiation source for generating a radiation beam comprising high-energy photons with low energy distributions for high contrast imaging along with high energy distributions for efficient treatment dose delivery. The radiation source includes a charged particle accelerator that generates charged particles having energies of less than 6 megavolts (MV), a target to receive the charged particles and generate the high-energy photons of the radiation beam, and a collimator to emit the radiation beam. The system further includes an imaging device of high detective quantum efficiency to define a target region of the tumorous tissue in the patient using the radiation beam, and a controller to determine the shape and modulate the dose for treatment of the tumorous tissue based on the defined target region, using the radiation beam.

    摘要: Generally, a method or apparatus for tomographically imaging a sample, such as a tumor of a patient, using positively charged particles positions n two-dimensional detector arrays on n surfaces of a scintillation material or scintillator, respectively. Resultant from energy transfer from the positively charged particles, secondary photons are emitted from the scintillation material and detected by the plurality of two-dimensional detector arrays, where each detector array images the scintillation material. Combining signals from the plurality of two-dimensional detector arrays, the path, position, energy, and/or state of the positively charged particle beam as a function of time and/or rotation of the patient relative to the positively charged particle beam is determined and used in tomographic reconstruction of an image of the sample or the tumor.

    摘要: To overcome the difficulties inherent in conventional proton therapy systems, new techniques are described herein for synchronizing the application of proton radiation with the periodic movement of a target area. In an embodiment, a method is provided that combines multiple rescans of a spot scanning proton beam while monitoring the periodic motion of the target area, and aligning the applications of the proton beam with parameters of the periodic motion. For example, the direction(s) and frequency of the periodic motion may be monitored, and the timing, dose rate, and/or scanning direction and spot sequence of the beam can be adjusted to align with phases in the periodic motion

The ultrasound imaging unit (26) includes a transducer (30) that emits ultrasonic sound waves to image in real-time an anatomic portion of a subject (16) in a first coordinate system. The radiation therapy delivery mechanism (12, 56, 70, 88) delivers amounts of therapeutic radiation in the anatomic portion of the subject in a second coordinate system. The fiducials (22, 90) include implants or a trans-rectal ultrasound probe (80). The image fusion unit (40) registers locations of the plurality of fiducials to at least one of the first and the second coordinate system and tracks the locations of the fiducials in real-time. The delivery evaluation unit (38) identifies locations and the amounts of delivered therapeutic radiation relative to the imaged real-time anatomic portion of the subject.

    摘要: Photon-based radiosurgery is widely used for treating local and regional tumors. The key to improving the quality of radiosurgery is to increase the dose falloff rate from high dose regions inside the tumor to low dose regions of nearby healthy tissues and structures. Dynamic photon painting (DPP) further increases dose falloff rate by treating a target by moving a beam source along a dynamic trajectory, where the speed, direction and even dose rate of the beam source change constantly during irradiation. DPP creates dose gradient that rivals proton Bragg Peak and outperforms Gamma Knife® radiosurgery.

    摘要: There is presented a method 100 and apparatus 200 to measure the surface of the patient (thorax and abdominal regions), e.g., during therapy delivery and (if necessary) while imaging. Together with biomechanical considerations the position of internal structures of the patient, such as an organ, and optionally a tumor in an organ, is inferred from the measured patient surface. In case the patient breaths and thus the organ and/or tumor moves, the position may be determined, which may be advantageous during, e.g., radiation therapy, since it enables that whenever the tumor is at the right position according to the radiation therapy plan, the radiation is switched on. In a specific embodiment, a finite element model is employed.
