Medical image processing apparatus and medical image processing method

A medical image processing apparatus, comprising

• processing circuitry configured to:
• acquire geometry of a coronary artery depicted in data of images relating to a heart,
• calculate a fractional flow reserve (FFR) value of the acquired coronary artery, based on the acquired geometry of the coronary artery,
• specify a responsible blood vessel of an ischemic region or a myocardial infarction region;
• and
• a display to display (1) the FFR value on a 2D curved planar image that depicts the specified responsible blood vessel wherein a first axis of the 2D curved planar image represents a long axis of the specified responsible blood vessel and a second axis of the 2D curved planar image represents a short axis of the specified responsible blood vessel, and (2) a graph having a third axis representing FFR values of the specified responsible blood vessel and a fourth axis representing spatial locations for the FFR values, wherein the first and third axes are aligned to a scale of the 2D curved planar image.

A medical image processing system comprising a medical image diagnosis apparatus and a medical image processing apparatus,

• the medical image diagnosis apparatus configured to specify a myocardial region of a heart by contrast imaging;
• the medical image processing apparatus comprising processing circuitry configured to:
• acquire geometry of a coronary artery depicted in data of images relating to the heart, calculate a fractional flow reserve (FFR) value of the acquired coronary artery, based on the acquired geometry of the coronary artery,
• specify a responsible blood vessel of an ischemic region or a myocardial infarction region based on the myocardial region specified by the medical image diagnosis apparatus;
• and
• a display to display (1) the FFR value on a 2D curved planar image that depicts the specified responsible blood vessel wherein a first axis of the 2D curved planar image represents a long axis of the specified responsible blood vessel and a second axis of the 2D curved planar image represents a short axis of the specified responsible blood vessel, and (2) a graph having a third axis representing FFR values of the specified responsible blood vessel and a fourth axis representing spatial locations for the FFR values, wherein the first and third axis aligned to a scale of the 2D curved planar image.

A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a method comprising:

• acquiring geometry of a coronary artery depicted in data of images relating to a heart,
• calculating a fractional flow reserve (FFR) value of the acquired coronary artery, based on the acquired geometry of the coronary artery,
• specifying a responsible blood vessel of an ischemic region or a myocardial infarction region;
• and
• displaying, to a display, (1) the FFR value on a 2D curved planar image that depicts the specified responsible blood vessel wherein a first axis of the 2D curved planar image represents a long axis of the specified responsible blood vessel and a second axis of the 2D curved planar image represents a short axis of the specified responsible blood vessel, and (2) a graph having a third axis representing FFR values of the specified responsible blood vessel and a fourth axis representing spatial locations for the FFR values, wherein the first and third axis aligned to a scale of the 2D curved planar image.
