Medical image storage and reproduction apparatus, method, and program

A medical image storage and reproduction apparatus, comprising:

• a storage unit that stores a motion picture obtained by continuously capturing a plurality of two-dimensional images while imaging inner portions of a bronchus with an endoscope;
• a virtual image generation unit that generates a virtual two-dimensional endoscopic image representing the inner portions of the bronchus based on a three-dimensional medical image obtained by imaging outside of the bronchus in advance;
• a chapter information assignment unit that detects a branch of the bronchus from the virtual endoscopic image and assigns chapter information to the motion picture, thereby segmenting the motion picture, based on the detected branch of the bronchus from the virtual image, and based on a detection point in time of the detected branch of the bronchus, wherein the motion picture is segmented by the chapter information which is based on the detected branch of the bronchus and the detection point from the virtual two-dimensional endoscopic image;
• and
• a display control unit that displays a selection screen, which is for receiving selection of one or more pieces of chapter information from a plurality of pieces of chapter information, on a display unit by displaying the plurality of pieces of chapter information assigned to the motion picture for the three-dimensional medical image based on positional information of a branch of the bronchus on the three-dimensional medical image and the display control unit displays the virtual two-dimensional image with the chapter information on the display unit,
• wherein the display control unit reproduces the stored motion picture that has been segmented based on the chapter information received on the selection screen, and displays the reproduced motion picture on the display unit.

A medical image storage and reproduction method for storing a motion picture obtained by continuously capturing a plurality of two-dimensional images while imaging inner portions of an imaging target and reproducing the stored motion picture, comprising:

• generating a virtual two-dimensional image representing the inner portions of the imaging target based on a three-dimensional medical image obtained by imaging outside of the imaging target in advance;
• detecting an anatomical feature or a functional feature from the virtual image corresponding to an updated frame according to updating of each frame of the motion picture and assigning chapter information to the motion picture, thereby segmenting the motion picture, based on the detected anatomical feature or the detected functional feature from the virtual image, and based on a detection point in time of the detected anatomical feature or the detected functional feature, wherein the motion picture is segmented by the chapter information which is based on the detected feature and the detection point from the virtual two-dimensional image;
• displaying a selection screen, which is for receiving selection of one or more pieces of chapter information from a plurality of pieces of chapter information assigned to the motion picture, on a display unit, and displaying the virtual two-dimensional image with the chapter information on the display unit;
• and
• reproducing the stored motion picture that has been segmented based on the chapter information received on the selection screen and displaying the reproduced motion picture on the display unit.

A non-transitory computer readable medium storing a program that causes a computer to execute a process for storing a motion picture obtained by continuously capturing a plurality of two-dimensional images while imaging inner portions of an imaging target and reproducing the stored motion picture, the process comprising:

• generating a virtual two-dimensional image representing the inner portions of the imaging target based on a three-dimensional medical image obtained by imaging outside of the imaging target in advance;
• detecting an anatomical feature or a functional feature from the virtual image corresponding to an updated frame according to updating of each frame of the motion picture and assigning chapter information to the motion picture, thereby segmenting the motion picture, based on the detected anatomical feature or the detected functional feature from the virtual image, and based on a detection point in time of the detected anatomical feature or the detected functional feature, wherein the motion picture is segmented by the chapter information which is based on the detected feature and the detection point from the virtual two-dimensional image;
• displaying a selection screen, which is for receiving selection of one or more pieces of chapter information from a plurality of pieces of chapter information assigned to the motion picture, on a display unit, and displaying the virtual two-dimensional image with the chapter information on the display unit;
• and
• reproducing the stored motion picture that has been segmented based on the chapter information received on the selection screen and displaying the reproduced motion picture on the display unit.
