As a safe and.convenient imaging technology.in clinical routine d.agnosis, ultrasound.imaging can provid. real-time 2d.images of internal tissues and.organs. To realize real-time 3d.image reconstruction, pixel nearest neighbor interpolation(PNN) reconstruction algorithm and.Bezier interpolation algorithm are combined.into a hy.rid.reconstruction algorithm. On this basis, a real-time interactive 3d.ultrasound.imaging sy.tem is *** temporal calibration and.spatial calibration, the six d.grees of freed.m poses of 2d.ultrasound.images can be accurately.collected. The 3d.volume reconstructed.by.the proposed.3d.reconstruction algorithm is visualized.by.volume rend.ring. A multi-thread.software sy.tem allows parallel operation of d.ta acquisition, 3d.reconstruction,volume visualization and.other functions. 3d.imaging experiments on a 3d.printing femur mod.l, a neck phantom and.the neck of human volunteers were performed.for sy.tematic evaluation. When the reconstruction voxel size was set to be(0.53 mm3, 1.03 mm3, 1.53 mm3), the reconstruction errors of the femur and.trachea mod.l were respectively.0.23 mm, 0.31 mm, 0.56 mm) and.0.62 mm, 0.88 mm, 1.41 mm). Clinical feasibility.was d.monstrated.by.application of the 3d.ultrasound.imaging on the neck of human volunteers.
