Abstract
A method of collecting information regarding an anatomical object of interest includes displaying an image characterized by a first region and a second region, wherein the first and second regions are mutually exclusive and the object is displayed within the second region, selecting first and second points spanning the object in the displayed image, at least one of the points being within the first region, and extracting a plurality of statistical values from image voxels, lying on a line segment between the first and second points, that correspond to the object.
Claims20
A method of collecting information regarding an anatomical object of interest from image voxels in a digital image, the method executed at least in part on a computer, comprising:
- displaying the digital image characterized by a background region and a second region, wherein the background and second regions are mutually exclusive and the anatomical object of interest is displayed within the second region;
- selecting first and second points spanning the anatomical object of interest in the displayed image, at least one of the first and second points being within the background region;
- evaluating image voxels lying on a line segment between the first and second points that correspond to the anatomical object of interest and obtaining one or more statistical values from the evaluated voxels;
- processing the digital image according to the obtained one or more statistical values;
- and
- displaying the processed digital image.
A method of collecting information regarding an anatomical object of interest, from image voxels in a digital image, the method executed at least in part on a computer, comprising:
- displaying the digital image illustrating a background region and a second region, wherein the anatomical object of interest is displayed within the second region;
- selecting and displaying first and second points spanning the anatomical object of interest in the displayed image, at least one of the first and second points being within the background region;
- evaluating image voxels lying on a line segment between the first and second points that correspond to the anatomical object of interest and obtaining one or more statistical values from the evaluated voxels;
- determining a median statistical value from the one or more obtained statistical values;
- determining an upper threshold value and a lower threshold value based on the median statistical value;
- segmenting the anatomical object of interest within the digital image according to the upper and lower threshold values;
- and
- displaying the segmentation results.
A method of collecting information regarding an anatomical object of interest within a digital image comprising a plurality of image voxels, the method executed at least in part on a computer, comprising:
- displaying an image of a boundary of the anatomical object of interest;
- selecting first and second points proximate the boundary, the first and second points approximating end points of a maximum diameter defined by the boundary;
- generating a first boundary point, the first boundary point being formed by the intersection of the boundary, and a line passing through the first and second points;
- generating a second boundary point, the second boundary point being formed by the intersection of the boundary and the line;
- extracting one or more statistical values from image voxels corresponding to points on the line between the first and second boundary points;
- and
- processing the digital image according to the extracted one or more statistical values and displaying the processed digital image.
