One-stop BPA operation system based on three-dimensional OCT real-time imaging

The invention provides a one-stop BPA operation system based on three-dimensional OCT real-time imaging, which comprises a scanning light source and light source driving module, a main interference module, a rotating and withdrawing mechanism module, a balance detection module, a data acquisition module, a work station and a catheter module, and is characterized in that the scanning light source and light source driving module is connected with the main interference module through a first optical fiber coupler; the main interference module is connected with a second optical fiber coupler through a first circulator, the second optical fiber coupler is connected with a data acquisition module through a balance detection module, and the data acquisition module is connected with the input end of a work station. A two-dimensional cross section image is reconstructed into a three-dimensional pulmonary artery blood vessel diagram through a computer reconstruction technology, the BPA operation curative effect is impr
