    摘要: A system and method for analyzing three-dimensional image data are disclosed herein. The system includes a processor configured to generate an overview image of at least a portion of a patient. The processor is configured to generate a cross-sectional image including a cross-sectional view of the overview image. The processor is also configured to generate a statistical image showing a parameter value relating to the portion of the patient shown in the overview image. The system also includes a visual output device connected to the processor. The visual output device is configured to display the overview image, the cross-sectional image, and the statistical image generally simultaneously. Also, the overview image, the cross-sectional image, and the statistical image are interconnected such that an update, change, or input applied to any one of the images results in an update to one or more of the other images.

    摘要: A method and apparatus for multi-phase cardiac CT imaging includes an adaptive, selective reconstruction process that, when possible, implements an image or non-phase location driven reconstruction process to reconstruct cardiac CT images. If the hardware parameters support an image location driven reconstruction for the particular imaging session then the image location driven reconstruction is implemented. However, if image location driven reconstruction is not supported, a default phase location driven reconstruction is employed. Image location driven reconstruction improves system throughput and improves image quality as more cardiac phase locations can routinely be generated to better “freeze” the motion of the heart of a patient.

    摘要: A method of modifying a segmented volume is disclosed herein. The method includes generating a reduced-resolution segmentation mask including a segmented region. The method includes performing a morphological erosion on the segmented region to form an eroded region and performing a morphological dilation on the eroded region to form a dilated region. The method also included identifying a leakage region in the segmented volume based on the dilated region and removing the leakage region from the segmented region to form an updated segmented volume.

    摘要: Systems, method and apparatus in which some implementations of respiratory structure imaging includes tracking a portion in a organ, determining wall contours in the portion and color-coding confidence in the wall contours. Some implementations of the color-coding includes selecting a cross section of a portion, determining average intensity of a wall in the organ from equally space ray vectors, determining confidence from a distribution of the average intensity, labeling sections of an organ image in reference to the average intensity, and color coding sections of the image in the memory according to the confidence.
