  • Patent number: 11027153
    Abstract: A radiation therapy system is configured to enable imaging and treatment of a target volume during a single patient breath hold. The radiation system includes a rotating gantry on which are mounted a treatment-delivering X-ray source and multiple imaging X-ray sources and corresponding X-ray imaging devices. The multiple imaging X-ray sources and X-ray imaging devices enable the acquisition of volumetric image data for the target volume over a relatively short rotational arc, for example 30 degrees or less. Therefore, intra-fraction motion can be detected in near-real time, for example within about one second or less. The radiation therapy system can perform image guided radiation therapy (IGRT) that monitors intra-fraction motion using X-ray imaging. Detected anatomical variations can then either be compensated for, via patient repositioning and/or treatment modification, or the current treatment can be aborted.

  • Patent number: 11006921
    Abstract: Versatile, multimode radiographic systems and methods utilize portable energy emitters and radiation-tracking detectors. The x-ray emitter may include a digital camera and, optionally, a thermal imaging camera to provide for fluoroscopic, digital, and infrared thermal imagery of a patient for the purpose of aiding diagnostic, surgical, and non-surgical interventions. The emitter may cooperative with an inventive x-ray capture stage that automatically pivots, orients and aligns itself with the emitter to maximize exposure quality and safety. The combined system uses less power, corrects for any skew or perspective in the emission, allows the subject to remain in place, and allows the surgeon's workflow to continue uninterrupted.

  • Patent number: 11006914
    Abstract: A system including initialization, imaging, alignment, processing, and setting modules. The initialization module obtains patient parameters for a patient and procedure and surgeon parameters. The initialization module selects first settings for an x-ray source based on the patient, procedure, and surgeon parameters. The image module obtains a first sample set of images of a region-of-interest of the patient and a master sample set of images. The first sample set was acquired as a result of the x-ray source operating according to the first settings. The alignment module aligns the first sample set to the master sample set. The processing module processes pixel data corresponding to a result of the alignment based on a pixel parameter or one of the patient parameters. The setting module adjusts the first settings to provide updated settings. X-ray dosage associated with the updated settings is less than x-ray dosage associated with the first settings.
