摘要： A transmitter/receiver transmits and receives ultrasonic waves to and from a desired region of a subject via an ultrasonic probe. A signal processor obtains a plurality of physical quantities from signals outputted by the transmitter/receiver having received ultrasonic echoes from the subject. A voxel-value generator generates a voxel value containing the plurality of physical quantities. An image generator generates a three-dimensional image by using the plurality of physical quantities including any of the rate, power value or dispersion of a blood flow contained in the voxel value and sequentially executing a rendering process on each voxel. A display controller controls a display to display the generated three-dimensional image.

摘要： An ultrasound diagnosis system, a medical image display apparatus and displaying method that simultaneously acquires virtual endoscopy image data and multi-planar-reconstruction (MPR) image data of a diagnosing target region based on the volume data acquired from an object. Virtual endoscopy image data is generated by setting up a viewing point and a viewing direction on a volume data acquired from the object. A marker is provided on a target region of a lumen organ shown in the virtual endoscopy image data for setting up an observing direction. A reference line started from the volume data is set up along an observing direction. By comparing a voxel value of the volume data that is crossing to the reference line with a prescribed threshold value, a reference point where a surface of the diagnosing target region crosses the reference line is set up to the volume data. MPR image data is generated by extracting each voxel of the volume data corresponded to each of three MPR cross-sectional planes that are mutually orthogonally crossing at the reference point and displayed with the virtual endoscopy image data.
