摘要： A medical image processing apparatus has a parameter calculating unit, a storage unit, and an image generating unit. The parameter calculating unit analyzes data of a plurality of time-series medical images, each containing an image of an organ having a functional blood vessel and a feeding blood vessel, and calculates a parameter based on at least a blood volume in the feeding blood vessel. The storage unit stores in advance a table that associates parameters with degrees of a cancer progression of the organ. The image generating unit refers to the table, obtains a degree of the cancer progression corresponding to the calculated parameter, and generates an image to which the obtained degree is applied on a region-by-region basis.

摘要： For a three-dimensional region including a treatment target site of a patient, a puncture needle scanning region R1 having a slice thickness d1 is set with reference to a cross section (a puncture cross section) including an insertion direction of a puncture needle. Subsequently, in the y-direction substantially perpendicular to the puncture cross section, two treatment target scanning regions R2 (R21 and R22) each being adjacent to the puncture needle scanning region R1 and having a slice thickness d2 are set. Then, based on volume data in the puncture needle scanning region R1 acquired by first three-dimensional scan with ultrasound waves and volume data in the treatment target scanning regions R2 acquired by second three-dimensional scan performed at a lower volume rate than the first three-dimensional scan, image data is generated for the purpose of supporting puncture.

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.
