Abstract: Systems/techniques that facilitate customized exceptions for intelligent protocoling are provided. In various embodiments, a system can access a data candidate associated with a medical patient. In various aspects, the system can execute a trained machine learning model on the data candidate, thereby identifying a first medical imaging protocol to be performed by a medical imaging scanner on the medical patient. In various instances, the system can determine whether the data candidate triggers a conditional protocol exception, wherein the conditional protocol exception identifies a second medical imaging protocol that is to be implemented when a condition is satisfied by the data candidate. In various cases, the system can, in response to determining that the data candidate satisfies the condition, select the second medical imaging protocol to be performed by the medical imaging scanner on the medical patient instead of selecting the first medical imaging protocol.

Abstract: Methods and systems are provided for aiding a subject of a medical imaging exam in performing coached breathing. In one embodiment, a method for a medical imaging system comprises generating a three-dimensional (3-D) virtual representation of a portion of a surface of a chest and/or abdomen of a subject of the medical imaging system, the portion adjustable in size by an operator of the medical imaging system; displaying changes in the 3-D virtual representation to the subject on a display device of the medical imaging system while the subject breathes, in real time; displaying instructions to the subject on the display device to perform coached breathing in accordance with a selected breathing pattern, using the 3-D virtual representation as a guide; and in response to detecting a deviation of a breathing pattern of the subject from the selected breathing pattern, indicating the deviation to the subject.

Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method includes processing acquired projection data of a monitoring area of a subject to measure a contrast signal of a contrast agent delivered to the subject, determining a hemodynamic marker of the subject based on the contrast signal, generating a scan prescription based on the determined hemodynamic marker of the subject, and performing a multi-phase contrast scan according to the scan prescription.

Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method includes, upon a first contrast injection of a first contrast bolus, processing acquired projection data of a subject to measure a contrast signal of the first contrast bolus, setting a timing for a second contrast injection of a second contrast bolus to a fallback injection timing, and responsive to identifying an adaptive injection timing for the second contrast injection based on the contrast signal before the fallback injection timing is reached, updating the timing for the second contrast injection to the adaptive injection timing and commanding initiation of the second contrast injection at the adaptive injection timing, otherwise commanding initiation of the second contrast injection at the fallback injection timing.

Abstract: Systems and methods for obtaining images are described. A method may include detecting a patient residing on a table proximate the system and detecting one or more artifact areas within an anatomical scan range of the patient. In some examples, the method can include generating an artifact area indicator for the system to display, wherein the artifact area indicator comprises data indicating a location for each of the one or more artifact areas that reside within the anatomical scan range of the patient.

Abstract: The present disclosure relates to systems and methods for monitoring and guiding patient motion during medical image acquisition. In accordance with certain embodiments, a method includes acquiring an image of a patient with an imaging system; determining an amount of patient movement; and providing a movement indicator based on the determined amount of patient movement.

Abstract: Various methods and systems are provided for generating a guided workflow and assisting in clinical decision making during operation of an imaging system at a site. Via a protocol manager interface, displaying a default protocol generated for the imaging system by a manufacturer, an authorized user may customize the protocol for the site. A workflow, in accordance with the modified protocol, is then displayed to another non-authenticated user at a time of operating the imaging system for an active scan.

Abstract: Various methods and systems are provided for displaying to an operator an attenuation map of a filter relative to a current location of an anatomical feature of a subject; and in response to the anatomical feature being within a region of the attenuation map, prompting an operator to reposition the subject. In this way, centering of the anatomical feature relative to an attenuation system may be facilitated for improved image quality.

Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method for a computing device communicatively coupled to an imaging system includes, selecting a scan protocol, displaying an adaptive scan protocol graphical user interface (GUI) on a display device coupled to the computing device, adjusting one or more parameters of the scan protocol in response to user input to the adaptive scan protocol GUI, updating a visual representation of the scan protocol displayed via the adaptive scan protocol GUI in correspondence to the adjustment of the one or more parameters of the scan protocol, and storing the adjusted scan protocol in memory of the computing device.
