Abstract: The present approach relates to detection of image artifacts symptomatic of needed calibration and/or failing hardware with no or limited human intervention, such as using machine learning. Detection of image artifacts can occur as part of normal imaging system operation and/or as part of a quality assessment of a newly manufactured or already installed system. Detection of image artifacts can adapt or learn as new scans are acquired using supervised or semi-supervised learning. Assessment of system imaging performance in the recently manufactured as well as the installed base can be performed reliably and automatically.

Abstract: A tilting head support for use in medical imaging is described. The tilting head support allows a patient to receive the equivalent of a tilted gantry exam study even when using a scanner gantry that does not tilt. In certain embodiments, the tilted head support assembly has metallic or sharp edge components, if present, positioned outside the imaging area when in use. In addition, in certain embodiments, the tilted head support assembly allows for user selection of a tilt angle from among a continuous range of available angles.

Abstract: Methods and systems are provided for indirectly measuring a current of a radiation source. In one embodiment, a method comprises generating a scan dataset by transmitting a radiation from a radiation source directly to a detector; calculating a signal to noise ratio of the scan dataset; and determining a current that was used to generate the scan dataset based on the calculated signal to noise ratio. In this way, current of the radiation source may be evaluated without connecting extra equipment to the radiation source.

Abstract: A patient support system includes a support beam that may translocate along an axial axis of a medical imaging system. At least a portion of the support beam may be disposed within a central bore of the medical imaging system. The patient support system also includes a patient support removably coupled to the support beam and including a backing that may support a patient during an imaging procedure and a restraint extending a longitudinal length of the backing. The restraint includes a first end coupled to the backing and a second end that may be removably coupled to the support beam, and the restraint may secure the patient support to the support beam and to restrain the patient within the patient support.

Abstract: Methods and systems are provided for improving image quality with three-dimensional (3D) scout scans for computed tomography (CT) imaging. In one embodiment, a method comprises reconstructing an image from projection data acquired during a diagnostic scan of a patient with corrections based on scout projection data acquired during a 3D scout scan of the patient. In this way, the image quality of a diagnostic image can be improved by using 3D scout data to correct projection data or image data.
