Image processing apparatus, image processing method, medical image diagnostic system, and storage medium

An image processing method for an image processing apparatus, comprising:

• an obtaining step of obtaining three-dimensional image data and positions of a plurality of feature points in the three-dimensional image data;
• a designation step of designating a designation point indicating a portion of interest in the three-dimensional image data;
• a selection step of selecting, using information determined by a position of the designation point and the positions of the plurality of feature points, a feature point from the plurality of feature points;
• a generation step of generating, from the three-dimensional image data, a cross section image on a plane determined based on the position of the designation point and a position of the selected feature point;
• and
• a display control step of causing a display unit to display the generated cross section image.

A non-transitory computer-readable storage medium storing a program for causing a computer to function as each unit of an image processing apparatus comprising:

• an obtaining unit configured to obtain three-dimensional image data and positions of a plurality of feature points in the three-dimensional image data;
• a designation unit configured to designate a designation point indicating a portion of interest in the three-dimensional image data;
• a selection unit configured to select, using information determined by a position of the designation point and the positions of the plurality of feature points, a feature point from the plurality of feature points;
• a generation unit configured to generate, from the three-dimensional image data, a cross section image on a plane determined based on the position of the designation point and a position of the selected feature point;
• and
• a display control unit configured to cause a display unit to display the generated cross section image.

A medical image diagnostic system comprising:

• an imaging unit configured to image three-dimensional image data;
• an obtaining unit configured to obtain three-dimensional image data and positions of a plurality of feature points in the three-dimensional image data;
• a designation unit configured to designate a designation point indicating a portion of interest in the three-dimensional image data;
• a selection unit configured to select, using information determined by a position of the designation point and the positions of the plurality of feature points, a feature point from the plurality of feature points;
• a generation unit configured to generate, from the three-dimensional image data, a cross section image on a plane determined based on the position of the designation point and a position of the selected feature point;
• and
• a display control unit configured to cause a display unit to display the generated cross section image.
