摘要： As an ROI for display and an ROI for valve observation as well as a projecting direction are input, a volume-rendering processing unit creates a first image in the ROI for display through volume rendering processing, and the ray-tracing processing unit creates a second image in the ROI for valve observation through ray tracing processing. An image compositing unit then creates a composite image by compositing the first image and the second image, and the composite image created by the image compositing unit (13) is displayed on a monitor.

摘要： An imaging part transmits ultrasonic waves to a subject and receives reflected waves from the subject, thereby acquiring plural volume data of the subject. A specifying part specifies a surface site included in a face corresponding to the surface of the subject, in each of the plural volume data. A synthesizer executes position matching of the subject shown in each of the plural volume data. The synthesizer couples the plural volume data after position matching, and couples the respective surface sites specified in the respective volume data, thereby generating synthesized volume data. Based on the synthesized volume data, an image generator generates morphology image data showing the morphology of the subject and surface image data showing the coupled surface sites. A display controller controls a display to display a morphology image based on the morphology image data and a surface image based on the surface image data.

摘要： In one embodiment, a scanning unit repeatedly scans an internal region of an object with an ultrasonic wave at a predetermined frame rate via an ultrasonic probe. An image generation unit extracts a blood flow signal based on a Doppler effect from a reflection signal and repeatedly generates a blood flow image representing a spatial distribution associated with power of the blood flow signal at the frame rate. A power average value associated with a frame or local region is calculated for the blood flow image. The blood flow image is corrected. In the correcting, a gain on the power values in the frame or local region in which the power average value exceeds the threshold are substantially reduced, and power values in the frame or local region in which the power average value is not more than the threshold are maintained.
