20090080734 | DIAGNOSIS SUPPORT SYSTEM - A region of interest is set by region of interest setting means in each of medical images obtained in chronological order. Similar case search means searches for a case information set including a case image having a region of similar pictorial characteristics to each of the regions of interest. When the corresponding case information set has been extracted through the search, case information display means displays test result information sets including not only the case images of similar pictorial characteristics but also all case images, test purposes, findings, and the like in the case information sets in chronological order of tests. | 03-26-2009 |
20090262998 | Image Display Apparatus, Image Display Control Method, and Computer Readable Medium Having an Image Display Control Program Recorded Therein - Specification is received regarding which structure identifying information, each corresponding to an anatomical structure, is specified as display target structure identifying information to be displayed with a display target image when displaying the display target image, in which the positions of each pixel correspond to positions within an original image. The position of the anatomical structure identified by the structure identifying information is specified, based on structure information, in which structure identifying information that identifies anatomical structures and structure position information that represents the positions of the anatomical structures within the original image are correlated, and the correspondence of positions between the original image and the display target image. The display target structure identifying information is displayed with the display target image such that a user can recognize that the anatomical structure identified by the display target structure identifying information is displayed at the specified position. | 10-22-2009 |
20110130653 | VERTEBRA SEGMENTATION APPARATUS, VERTEBRA SEGMENTATION METHOD, AND RECORDING MEDIUM WITH PROGRAM FOR VERTEBRA SEGMENTATION - Based on generated tomographic images, a first feature quantity representative of a clearness of sectional shapes crossing the Z′ axis at the vertebrae is calculated for each of respective points on the Z′ axis. Further, based on the generated tomographic images, a second feature quantity representative of a clearness of sectional shapes parallel to the Z′ axis at the vertebrae is calculated for each of the respective points on the Z′ axis. A third feature quantity representative of a regularity of an array of the vertebrae is calculated for each of the respective points on the Z′ axis, based on the calculated first feature quantity and the calculated second feature quantity. Positions of the vertebrae on the Z′ axis are calculated based on the third feature quantity, which is calculated for each of respective points on the Z′ axis. | 06-02-2011 |
20110194744 | MEDICAL IMAGE DISPLAY APPARATUS, MEDICAL IMAGE DISPLAY METHOD AND PROGRAM - A medical image display apparatus includes an image database for recording a three-dimensional standard image of a model subject, a three-dimensional anatomical image corresponding to the three-dimensional standard image, and anatomical information on living tissue names, an image acquirer for acquiring a three-dimensional medical image of an examinee, a medical tomographic image identifier for identifying a medical tomographic image in the three-dimensional medical image based on a user's instruction, a standard tomographic image identifier for identifying a standard tomographic image in the three-dimensional standard image, which corresponds to the medical tomographic image, an anatomical tomographic image identifier for identifying an anatomical tomographic image in the three-dimensional anatomical image, which corresponds to the standard tomographic image, and a display controller for displaying the medical tomographic image and the anatomical tomographic image on a display unit, while displaying the living tissue names over the anatomical tomographic image based on the anatomical information. | 08-11-2011 |
20130243285 | MEDICAL IMAGE ALIGNMENT APPARATUS, METHOD, AND PROGRAM - Generating, with respect to each of the three-dimensional image and the three-dimensional comparison image, a plurality of tomographic images orthogonal to a central axis of each vertebra of the subject along the central axis, calculating a first characteristic amount representing a profile in a direction orthogonal to the central axis at each point on the central axis based on the tomographic images, calculating a second characteristic amount representing a profile in a direction of the central axis at each point on the central axis based on the tomographic images, calculating a third characteristic amount representing regularity of disposition of each vertebra at each point on the central axis based on the calculated first and second characteristic amounts, and aligning positions of the third characteristic amount calculated from the three-dimensional image and the third characteristic amount calculated from the three-dimensional comparison image along the central axis. | 09-19-2013 |
20140294274 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD AND IMAGE PROCESSING PROGRAM - A first image and a second image obtained by imaging the same subject with different types of modalities are obtained. The first image is deformed, and similarity between the deformed first image and the second image is evaluated by an evaluation function that evaluates correlation between distributions of corresponding pixel values of the two images to estimate an image deformation amount of the first image. Based on the estimated image deformation amount, a deformed image of the first image is generated. The evaluation function includes a term representing a measure of correlation between a pixel value of the deformed first image and a corresponding pixel value of the second image, wherein the term evaluates the correlation based on probability information that indicates a probability of each combination of corresponding pixel values of the first image and the second image. | 10-02-2014 |
20140301623 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM - A first image and a second image are obtained; the amount of deformation of the first image is estimated by evaluating the degree of similarity between a deformed first image and the second image, using an evaluation function that evaluates the correlation between the distribution of corresponding pixel values within the two images; and an image, which is the first image deformed based on the estimated amount of deformation, is generated. The evaluation function evaluates the degree of similarity between the deformed first image and the second image, based on degrees of similarities of divided images that represent degrees of similarities among the distributions of pixel values of each pair of divided first images and divided second images, which respectively are images that the deformed first image is divided into and images that the second image is divided into, according to predetermined dividing conditions. | 10-09-2014 |
