A medical image processing apparatus according to an embodiment includes a reception unit and a detection unit. The reception unit is configured to receive two points specified on at least one sagittal image. The detection unit is configured to detect an intervertebral disc by evaluating a luminance distribution within a region that includes the two points.

Medical image processing apparatus, medical image processing method, and medical imaging device

A medical image processing apparatus according to an embodiment includes setting circuitry, calculation circuitry, and recognition circuitry. The setting circuitry is configured to set a region of interest (ROI) of each of a plurality of sagittal plane images of medical images resulting from scanning an examinee. The calculation circuitry is configured to calculate an evaluation index based on a bipolarity feature of each block in the ROI related to change of pixel values and a similarity feature among the blocks. The recognition circuitry is configured to select the ROI according to the calculation result of the calculation circuitry and recognize a sagittal plane image in which the selected ROI is located as a target sagittal plane image of a median sagittal plane passing through a spine.

The disclosure provides an image segmentation apparatus, an image segmentation method and a medical image device for segmenting an object having a tree-shaped tubular structure from a volume image consisting of a series of images photographed on the basis of slices. The image segmentation apparatus comprises: a self-adaptive region growing unit configured to perform region growing according to the volume image, based on a seed point and a preset threshold to obtain at least one part of the tree-shaped tubular structure; and a growing control unit configured to change the preset threshold to re-perform the region growing until a given condition is met.
