Embodiment approach

[0054] In one embodiment, the imaging procedure used to generate images of the region of interest is perfusion CT, which helps identify possible strokes, vascular occlusions, and brain and body tumors. Alternative brain scanning techniques such as PET, SPECT, or xenon CT that also reveal blood flow in the brain may also be used. Perfusion-weighted images can be used to measure brain perfusion, including cerebral blood flow, cerebral blood volume, and time to peak parameters. Images of the region of interest can then be generated using the perfusion data of the brain. For example, a diffused weighted image can be used to generate an image of a region of interest. Alternative ways of generating an image of a region of interest may also be used.

[0055] The interactive user assistant analyzes the displayed medical image and the underlying medical image data with expected medical image data stored in memory. The results of the comparison can be presented graphically to the use...

Abstract

An interactive user assistant for imaging processes analyzes medical image data pertaining to regions of interest. The user assistant compares displayed medical images and / or the data underlying the medical images with expected medical image data. The user assistant identifies whether or not the displayed medical image meets expectations or is plausible. The user assistant may use previously analyzed data in determining whether the displayed medical image is as expected. If the displayed medical image does not meet expectations, the user assistant determines whether or not the cause of the disagreement between the displayed and expected images is ascertainable. If the cause of the disparity between the images is ascertainable, the user assistant presents specific recommendations. If the cause of the disparity between the images is not ascertainable, the user assistant presents general suggestions.

Description

technical field [0001] The present invention generally relates to a system for assisting a user in an interactive software application. More specifically, the present invention relates to interactive software applications for performing medical imaging processes. Background technique [0002] Various types of contrast media can be injected into medical patients. Contrast agents are used to enhance the contrast of tissue or fluid in images of a patient. A series of internal scans of the patient can be recorded and processed as the contrast agent travels through a part of the body or region of interest. This series of internal scans can be used to create a contrast-enhancing curve about the region of interest. A contrast enhancement curve is a graph of the enhancement curve of a scan of a region of interest over a period of time. [0003] Images of internal regions of interest can be presented on a display with accompanying contrast-enhanced curves for analysis by medical ...
