    摘要： The invention relates to a frame for positioning a hand for medical imaging. In one embodiment, the frame includes a plate having a first surface and a second surface, and at least one indicium of handedness on one of the first and second surface. In the embodiment, at least one indicium of the frame is positioned asymmetrically on one of the first and second surfaces. In another embodiment, while, at least one of the first and second surfaces is flat, the other surface is shaped to raise the fingers of the hand, and has a raised platform to support the wrist of said hand. The indicium is visible under medical imaging illumination. Medical imaging is selected from a group consisting of: X-Ray, MRI (magnetic resonance imaging), computed tomography (CT), and PET (position emission tomography).

    摘要： Mammogram images are processed by computer to derive automatically a value for a parameter useful in detecting differences in breast tissue in subsequent images of the same breast or relative to a control group of such images, said derived parameter being a parameter that changes alongside changes in breast density and is hence useful in assessing cancer risk. The method comprises the steps of processing each image of at least part of a breast by: computing for pixels of the image a quotient value representative of the aspect ratio of tissue structures depicted in the image; using a trained classifier to classify said pixels according to their respective said quotient values and assigning a score to the respective pixels representing their classification with respect to at least two classes; deriving said parameter that changes alongside changes in breast density based on the aggregate pixel membership scores of said classes. The classifier may be trained either by unsupervised learning or by supervised learning.

    摘要： A method of processing a mammogram image to derive a value for a parameter useful in detecting differences in breast tissue in subsequent images of the same breast or relative to a control group of such images, said derived parameter being an aggregate probability score reflecting the probability of the image being a member of a predefined class of mammogram images, comprises computing for each of a multitude of pixels within a large region of interest within the image a pixel probability score assigned by a trained statistical classifier according to the probability of said pixel belonging to an image belonging to said class, said pixel probability being calculated on the basis of a selected plurality of features of said pixels, and computing said parameter by aggregating the pixel probability scores over said region of interest. Saud features may include the 3-jet of said pixels.

    摘要： A method for performing quality control on medical images in a clinical trial setting. In one embodiment, the method includes the steps of designating an image as reference image; obtaining attribute data from the reference image as reference attribute data; storing the reference image and the reference attribute data; subsequently taking a second image; obtaining attribute data from the second image as second attribute data; comparing the second image with the reference image on a single output screen; and denoting on the single output screen the second attribute data associated with the second image which differs from the reference data associated with the reference image.
