Abstract: A CT imaging system includes a gantry and a table in a movable relationship with the gantry. The CT imaging system also includes a controller configured to control relative movement between a subject disposed on the table and the gantry from a first data acquisition position to a second data acquisition position. The controller is also configured to determine a total scan time based on a first time for acquiring imaging data at the first data acquisition position and a second time for transitioning from the first data acquisition position to the second data acquisition position. The controller is also configured to disable data acquisition in an immediately subsequent cardiac cycle and re-enable data acquisition in the cardiac cycle following the immediately subsequent cardiac cycle if the total scan time exceeds one cardiac cycle of the subject. A method of CT imaging is also disclosed.

Abstract: A computer-implemented method for quantifying an object in a larger structure using a reconstructed image obtained from an imaging apparatus includes identifying an object boundary in a region of interest of the image and a region of exclusion, and determining a mean value of intensity in a neighborhood of the object to estimate a background value, excluding the region of exclusion. The method further includes determining an interior region, a transition region, and a background region of the object using the object boundary and a transfer function of the imaging apparatus, and determining and displaying a measure of object quantification utilizing intensities of at least one of the determined interior region or the transition region a method for quantifying an object in a larger structure using a reconstructed image obtained from an imaging apparatus.

Abstract: A method and system for prospectively acquiring data of a region of interest for retrospective re-analysis includes obtaining region of interest data and generating property information of the region of interest data. The method also includes analyzing the property information receptive to generating a measurement of the property information. After storing the property information, the property information is retrievable for further analysis.

Abstract: A method for analyzing tissue classes along a tubular structure defined by voxels is disclosed. A tubular shaped region of interest (ROI) is constructed along a predetermined centerline of the tubular structure according to the following: at least one point is defined along the centerline to define the extremities of the ROI; a diameter corresponding to the ROI is defined and/or computed; contiguous unit volumes are applied along the centerline between the extremities of the ROI; a first volume is computed by the union of the unit volumes; and, a final volume of the ROI is defined as the connex part of the first volume that contains the middle of the tubular structure. The final volume is then analyzed with respect to tissue classes present therein.

Abstract: A method and system for filtering medical images is described. The described method of filtering medical images includes receiving image data including a plurality of images from an image scan, determining a number of interpolation elements based on a slice thickness of the plurality of images, and filtering the image data using the determined interpolation elements.

Abstract: A method for filtering images is provided. The method includes obtaining at least one set of image data of a subject using an imaging system, removing at least one slice of image data from the at least one set to form a filtered set, and reconstructing images from the filtered set.

Abstract: A method includes receiving a multi-phase axial cardiac dataset, receiving a selection of a phase from a user, when the received selection is systole, generating an endocardial volume of a left ventricle at an end systole phase without further user intervention, and when the received selection is diastole, generating an endocardial volume of the left ventricle at an end diastole phase without further user intervention.
