摘要： A method for automated detection of abnormal anatomic regions, wherein a mammogram is digitized to produce a digital image and the digital image is processed using local edge gradient analysis and linear pattern analysis in addition to feature extraction routines to identify abnormal anatomic regions. Noise reduction filtering and pit-filling/spike-removal filtering techniques are also provided. Multiple difference imaging techniques are also used in which difference images employing different filter characteristics are obtained and processing results logically OR'ed to identify abnormal anatomic regions. In another embodiment the processing results with and without noise reduction filtering are logically AND'ed to improve detection sensitivity. Also, in another embodiment the wavelet transform is utilized in the identification and detection of abnormal regions. The wavelet transform is preferably used in conjunction with the difference imaging technique with the results of the two techniques being logically OR'ed.

摘要： A differential-image creating unit creates a three-dimensional image on which an artery is highlighted and a three-dimensional image on which a tumor is highlighted. An image compositing unit combines the three-dimensional images to composite an image. A display control unit displays the composite image on a monitor. Moreover, when compositing an image, the image compositing unit composites the image such that a tumor nutrient blood-flow inside and outside tumor is to be displayed in respective different colors. Furthermore, a blood-flow quantity inside tumor measuring unit calculates a blood-flow quantity inside tumor and a ratio of the blood-flow quantity inside tumor to a tumor volume, and the display control unit displays the blood-flow quantity inside tumor and the ratio of the blood-flow quantity inside tumor to the tumor volume. Accordingly, information that is meaningful for determining malignancy of a tumor can be provided.

摘要： A plurality of position data are input, which indicate the position of an observation target defined in a three-dimensional space, on its three-dimensional image, which is viewed from a predetermined view point along a predetermined line-of-sight direction. A curved cross-section in the line-of-sight direction is calculated from the plurality of position data and line-of-sight data including the predetermined view point and the predetermined line-of-sight direction. A projection image is generated by projecting the three-dimensional image on the calculated curved cross-section onto a projection surface along the line-of-sight direction. The projection image is then displayed.

摘要： When medical image data is acquired by imaging equipment of modality, modality outputs an image data transfer request command to a data base, via a network. After a memory area of a TMD (temporal magnetic disc) of the data base is secured, the acquired image data is transferred from modality to the TMD. When an image data retrieval request command is input from a WS (work station) of a console to data base through network, retrieval of the image data stored in the data base is performed, the retrieved data is transferred to the WS, and is displayed. The operator requests data base to read out image data by retrieval result. Data base is searched memory address of the requested image data. When the requested image data is stored in OD (optical disc), image data stored in OD is transferred to TMD. Image data stored in TMD is transferred to WS, and is displayed.
