US Patent 12094111 Analysis device, analysis system, and analysis method

An analysis device according to an embodiment includes processing circuitry. The processing circuitry extracts, from medical image data, the shape of a blood vessel of a subject and the shape of a plaque formed in the blood vessel. Then, while changing a first-type timing in sequence, the processing circuitry calculates a mechanical index, which is related to the plaque at the first-type timing, based on the shape of the blood vessel and the shape of the plaque at the first-type timing. Subsequently, based on the mechanical index at the first-type timing, the processing circuitry predicts the shape of the plaque at a second-type timing that is the next timing to the first-type timing. Then, the processing circuitry displays, in a display unit, the predicted shape of the plaque at the time second-type at which the plaque reaches a specific condition.
