Surgery assistance device, surgery assistance method, and computer program

A surgery assistance method comprising:

• acquiring three dimensional position information of a true lumen existing in a target blood vessel;
• acquiring an angiographic image of the target blood vessel from a flat panel detector (FPD) disposed at a first imaging position,
• generating a true lumen image representing the true lumen at a position and in a posture corresponding to the angiographic image by using position information of the first imaging position and the three dimensional position information of the true lumen;
• generating a composite image by compositing the angiographic image and the true lumen image;
• and
• outputting the composite image to a display.

A non-transitory computer readable medium storing a computer program that causes a processor to execute information processing, the information processing comprising:

• acquiring three dimensional position information of a true lumen existing in a target blood vessel;
• a acquiring an angiographic image of the target blood vessel from a flat panel detector (FPD) disposed at a first imaging position,
• generating a true lumen image representing the true lumen at a position and in a posture corresponding to the angiographic image by using position information of the first imaging position and the three dimensional position information of the true lumen;
• generating a composite image by compositing the angiographic image and the true lumen image;
• and
• outputting the composite image to a display.
