Abstract

Systems and methods for predicting a location of a target heart region for cardiac ablation can include one or more processors generating a 3D model of a heart of a patient based on medical images of the patient, and estimating, using the 3D model of the heart and electrophysiology data of the patient, one or more mechanical properties that drive motion of the patient's heart. The one or more processors can generate, using the 3D model and the one or more mechanical properties, a simulated motion pattern of the patient's heart over at least a portion of a cardiac cycle, and identify a region of interest (ROI) of the heart of the patient to be radiated. The one or more processors can determine, using the simulated motion pattern of the heart of the patient, a location of the ROI at a predefined time instance within the cardiac cycle.

Abstract

Systems and methods for simulating radiation effect for cardiac ablation can include a processor generating a heart simulation model configured to simulate electrical activities of the heart of the patient. The processor can determine a simulated post-radiation state of the heart of the patient by adjusting the heart simulation model to account for an effect of a radiation treatment plan on simulated electrical activities of the heart of the patient. The processor can simulate, using the adjusted heart simulation model, the simulated post-radiation state of the heart with a stimulation to induce a heart rhythm disorder, determine whether the heart rhythm disorder is induced based on electrical activities generated when simulating the simulated post-radiation state of the heart with the stimulation, and output an indication of whether the heart rhythm disorder is induced. The processor can suggest modifications to the radiation plan if the heart rhythm disorder is induced.

Abstract

A radiation dose received by a patient from a radiation therapy system can be verified by acquiring a cine stream of image frames from an electronic portal imaging device (EPID) that is arranged to detect radiation exiting the patient during irradiation. The cine stream of EPID image frames can be processed in real-time to form exit images providing absolute dose measurements at the EPID (dose-to-water values), which is representative of the characteristics of the radiation received by the patient. Compliance with predetermined characteristics for the field can be determined during treatment by periodically comparing the absolute dose measurements with the predetermined characteristics, which can include a predicted total dose in the field after full treatment and/or a complete irradiation area outline (CIAO). The system operator can be alerted or the irradiation automatically stopped when non-compliance is detected.

Abstract

A system can have an x-ray source that generates a series of individual x-ray pulses for multi-energy imaging. A first x-ray pulse can have a first energy level and a subsequent second x-ray pulse in the series can have a second energy level different from the first energy level. An x-ray imager can receive the x-rays from the x-ray source and can detect the received x-rays for image generation. A generator interface box (GIB) controls the x-ray source to provide the series of individual x-ray pulses and synchronizes detection by the x-ray imager with generation of the individual x-ray pulses. The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.

Abstract

A motion-enable device includes a mechanical switch and a capacitive sensor with a sensing region that is located adjacent to the mechanical switch. The mechanical switch enables a first signal when closed or actuated that indicates that the mechanical switch is in an active state. The capacitive sensor enables a second signal when a conductive object is disposed in the sensing region, where the second signal indicates that the capacitive sensor is in an active state. Enablement of operation of an apparatus depends on receipt of both the first signal and the second signal. The mechanical switch and the capacitive sensor act as the two separate switches required by functional safety requirements for a motion enable device. Because the sensing region of the capacitive sensor is adjacent to the mechanical switch, the first and second signals are generated when an operator actuates the mechanical switch with a single digit.

Abstract

Radiation treatment planning includes accessing values of parameters such as a number of beams to be directed into sub-volumes in a target, beam directions, and beam energies. Information that specifies limits for the radiation treatment plan are accessed. The limits include a limit on irradiation time for each sub-volume outside the target. Other limits can include a limit on irradiation time for each sub-volume in the target, a limit on dose rate for each sub volume in the target, and a limit on dose rate for each sub-volume outside the target. The values of the parameters are adjusted until the irradiation time for each sub-volume outside the target satisfies the maximum limit on irradiation time.
