摘要： A medical image processing apparatus includes a morphological identification part, a function calculator and a display processor. The morphological identification part identifies morphological information related to thickness of a heart muscle of a subject or thickness of surrounding sites thereof from medical image data obtained by capturing an image of the subject using a medical imaging apparatus. The function calculator determines cardiac function information related to movement of the heart muscle of the subject based on the medical image data. The display processor causes a display to display a combination of the identified morphological information and the calculated cardiac function information which is identified by color. The medical image processing apparatus can easily diagnose diseases.

摘要： An image processing display and an image processing display program that can prevent interference with catheter treatment even when the distal end of a catheter is located behind a treatment apparatus on X-ray fluoroscopic images. The image processing display displays X-ray fluoroscopic images to be obtained by looking through a region including blood vessels using X-rays during treatment, and includes a treatment apparatus image extractor and an image processor. The treatment apparatus image extractor, based on X-ray fluoroscopic images, extracts treatment apparatus images representing the treatment apparatus having the property of absorbing X-rays. The image processor determines the distal end position of the catheter to superimpose and display images representing the determined distal end position of the catheter on the region of the X-ray fluoroscopic images showing the treatment apparatus.

摘要： According to one embodiment, a three-dimensional image processing apparatus includes at least a storage, an inputting unit, an image generating unit and a pointer controlling unit. The storage stores volume data of a target. The inputting unit receives an input operation for moving a pointer. The image generating unit generates a superimposed image in which a rendering image generated by performing a rendering process on the volume data and a pointer image are superimposed in consideration of information of depth. The pointer controlling unit obtains information of a three-dimensional position of the pointer. When the pointer is on the rendering image, the pointer controlling unit moves the pointer along a three-dimensional surface of a target contained in the volume data.

摘要： Positioning images are created by a projection-image creating unit before imaging, and the positioning images are grouped and stored by a projection-image storage unit for each preset. When imaging is started, a positioning-information calculating unit calculates positioning parameters using the positioning images stored in the projection-image storage unit. An analysis-image-for-synthesis creating unit creates an analysis image using the positioning parameters, and an analysis-image synthesizing and displaying unit synthesizes the analysis image with a live image and displays a synthesized image. When an imaging direction of an X-ray angiography apparatus is changed, a positioning-information updating unit directly updates the positioning parameters based on an amount of change of the imaging direction.
