Abstract: Disclosed are various approaches for generating synthetic computer tomography (CT) images using magnetic resonance imaging A patient body outline (PBO) of a patient is obtained. Then, a magnetic resonance image set in a limited field of view (MRI-in-LFOV) of the patient is converted into a synthetic computed tomography (CT) image set in limited field of view (syn-CT-in-LFOV) of the patient. Next, the syn-CT-in-LFOV is expanded to a synthetic CT image set in full field of view (syn-CT-in-FFOV) of the patient based at least in part on the PBO.

Abstract: A motion compensation system includes a plurality of RF transmitters, a plurality of direction of arrival sensors, and a positioning table which together are usable to compensate for intrafraction motion of a patient during a medical procedure. The positioning table may be a secondary table arranged next to or above a primary table such as a radiotherapy couch, allowing for repositioning of part of patient such as the head and neck relative to a remainder of the body. The motion compensation system employs a direction of arrival sensor that includes rotating antenna elements in a configuration that improves the ease and accuracy of signal processing and analysis to identify the position of an RF transmitter affixed to a patient. The repositioning table has six degrees of freedom and is safe for use in imaging and radiation intensive environments.

Abstract: Digital modulated radiography improves radiographic image quality in the overall image and in sub-areas by enhancing image contrast in 2D/3D space. Devices and processes include a software-based approach using artificial intelligence (AI) to achieve energy modulation without the need for multiple exposures. By employing machine learning (ML) models, specifically Generative Adversarial Networks (GANs), images are translated between different energy domains, enhancing image contrast and potentially reducing radiation dose.
