MEDICAL IMAGE PROCESSING APPARATUS AND METHOD

A medical image processing apparatus includes a catheter including a sensor and insertable into a blood vessel, a display, and a processor configured to: control the catheter to acquire tomographic images of the vessel, input the images into a model and acquire information indicating a condition of a part of the blood vessel, generate a histogram of a plaque area ratio in the vessel, acquire a length of a stent to be placed or a lesion to be treated, calculate a threshold for the ratio using the first histogram and the length, generate a graph indicating the ratio at each part of the blood vessel, and control the display to display the graph and the threshold in an overlapping manner.
