Embodiment Construction
[0035] The following examples illustrate the specific implementation of the above process.
[0036] (1) Three-dimensional model reconstruction based on coronary CT images ( Figure 4 ). Three-dimensional reconstruction requires the use of software tools such as Mimics. Keep at least blood vessels with a diameter > 1 mm.
[0037] (2) According to the blood flow velocity data of the three main coronary vessels LAD / LCX / RCA measured by ultrasound, calculate the blood flow of the three main vessels according to the formula (2), such as: Q LAD , Q LCX and Q RCA .
[0038] (3) calculation Figure 4 The volume of branch vessels at all levels. The volume V of each branch vessel segment can be obtained by using software tools such as Mimics ij .
[0039] Follow the formula below to calculate the flow rate of each branch of the coronary artery layer by layer.
