Abstract
According to the embodiments, a medical image diagnosis apparatus includes a memory and processing circuitry. The memory stores volume data on a target portion including a vessel network and a plurality of blood vessels connected to the vessel network. The processing circuitry extracts the vessel network and the blood vessels from the volume data. The processing circuitry analyzes how hemodynamics in the vessel network are after treatment of the vessels.
Claims20
