    摘要： A patient-specific, restraining device is fabricated directly from the patient's diagnostic images, (e.g. Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Ultrasound) fabricated by additive manufacturing techniques, also known as 3D printing, using an algorithm that directly translates the medical images into instructions for the 3D printer. The patient-specific restraining device incorporates dosimetry devices to allow for real-time, near real-time or after-the-fact measurement of delivered radiation at the entry and exit points on the body. Using a patient's medical images and dose planning software, patient-specific dose calculations allows for the calculation of the predicted dose for each location of entry and exit of the beam on the restraining device. This restraining device and method may be used to measure irradiation dosages in real time, adjust dosage levels based on such measurements, and then deliver more accurate and precise treatments during advanced treatment techniques.

    摘要： An integrated system for radiation therapy that includes a synchrotron ion accelerator beam delivery system, and imaging system on the same compact rotating gantry is disclosed. An ion accelerator, accelerating charged particles, is mounted on an annular gantry that rotates about the patient to be treated. The charged particles may be protons or other heavier ions such as helium or carbon. The beam delivery system, which includes bending, focusing, and scanning magnets and other equipment for accurately delivering the ion beam to the patient, is integrated on the same rotating structure. An imaging system which in one embodiment is, but not limited to, a cone beam CT system. The accelerator and imaging system may be configured in a coplanar or non-coplanar arrangement with the rotation plane of the gantry and with the beam delivery system to allow for optimization of the size or functionality of the system.

    摘要： Disclosed are systems and methods for characterizing interactions or proton beams in tissues. In certain embodiments, charged particles emitted during passage of protons, such as those used for therapeutic and/or imaging purposes, can be detected at relatively large angles. In situations where beam intensity is relatively low, such as in certain imaging applications, characterization of the proton beam with charged particles can provide sufficient statistics for meaningful results while avoiding the beam itself. In situations where beam intensity is relatively high, such as in certain therapeutic applications, characterization of the proton beam with scattered primary protons and secondary protons can provide information such as differences in densities encountered by the beam as it traverses the tissue and dose deposited along the beam path. In certain situations, such beam characterizations can facilitate more accurate planning and monitoring of proton-based therapy.
