X-ray ct apparatus, medical image processing apparatus, method, and storage medium

A medical image processing apparatus comprising processing circuitry configured to

• acquire information on a structure serving as a target for segmentation,
• acquire information on an existence probability of the structure in a medical image on a basis of the information on the structure,
• set a segmentation region where segmentation of the structure is performed on a part of the medical image on a basis of the information on the existence probability of the structure, and
• perform segmentation of the structure on the segmentation region of the medical image.

A method comprising:

• acquiring information on a structure serving as a target for segmentation;
• acquiring information on an existence probability of the structure in a medical image on a basis of the information on the structure;
• setting a segmentation region where segmentation of the structure is performed on a part of the medical image on a basis of the information on the existence probability of the structure;
• and
• performing segmentation of the structure on the segmentation region of the medical image.

A non-transitory computer readable medium comprising instructions that cause a computer to execute:

• acquiring information on a structure serving as a target for segmentation;
• acquiring information on an existence probability of the structure in a medical image on a basis of the information on the structure;
• setting a segmentation region where segmentation of the structure is performed on a portion of the medical image on a basis of the information on the existence probability of the structure;
• and
• performing segmentation of the structure on the segmentation region of the medical image.
