  • Publication number: 20210093277
    Abstract: Methods and systems are provided for generating a diagnostic cardiac image using a CT system without ECG gating techniques. In one example, a method for an imaging system includes determining a scanning duration for scanning a heart of a patient with the imaging system based on a heart rate of the patient, scanning the patient with the imaging system for the scanning duration, the scanning commenced independent of a current phase of a cardiac cycle of the heart of the patient, and reconstructing an image from data acquired during the scanning.

  • Patent number: 10426424
    Abstract: A computer-implemented method for generating and simulating a computed tomography (CT) protocol is provided. The method includes receiving, via a graphical user interface, at a processor user input including patient population size settings and scan technique settings for modeling the effects of the scan technique settings across a patient population as a function of patient size. The method also includes generating, via the processor, a patient population profile based on at least the patient population size settings and the scan technique settings, wherein the patient population profile includes specific CT scan technique settings to be applied across different size ranges of the patient population as a function of patient size. The method further includes displaying, on the graphical user interface, one or more visualization elements illustrating the effect of these specific CT scan technique settings on specific imaging metrics across the patient population.

  • Publication number: 20190231288
    Abstract: Methods and systems are provided for contrast-enhanced diagnostic imaging. In one embodiment, a method comprises estimating a time to perform a diagnostic scan of a patient based on demographics of the patient, and performing the diagnostic scan of the patient at the estimated time responsive to a confidence level of the estimated time above a threshold. In this way, a contrast-enhanced diagnostic scan may be performed without directly monitoring the contrast flow, thereby reducing radiation dose and contrast load while maintaining or improving image quality.

  • Publication number: 20170325770
    Abstract: The present approach provides a non-invasive methodology for estimation of coronary flow and/or fractional flow reserve. In certain implementations, various approaches for personalizing blood flow models of the coronary vasculature are described. The described personalization approaches involve patient-specific measurements and do not assume or rely on the resting coronary flow being proportional to myocardial mass. Consequently, there are fewer limitations in using these approaches to obtain coronary flow and/or fractional flow reserve estimates non-invasively.

  • Patent number: 8811707
    Abstract: A system and method for distributed and coordinated image processing of tomographic images utilizing processors on a medical imaging device and a separate workstation is disclosed. The system includes an image acquisition device to acquire image data of a subject and an image processor to receive the image data therefrom. The image processor is programmed to reconstruct initial images of a region-of-interest (ROI) from the image data, identify initial images on which to perform image correction, and generate an image correction request for the images identified for image correction, with the image correction request specifying a processing operation to be performed on the respective images. The image processor is further programmed to transfer the reconstructed initial images to a separate workstation that automatically initiates the image correction upon verifying a presence of an image correction request on the initial images so as to generate corrected images.
