Technology of the Interactive 3D Measurement Based on Medical Image

The technology of 3D measurement has a great significance and potential applications in machine vision,automatic processing,industrial inspection and biomedical and other fields.But because the use of traditional measurement methods,many 3D measurements can only measure the surface points based on the surface rendering,which results in the internal organizations can not be measured.A measurement method based on volume rendering is presented that any position can be measured.A 3D measurement system of medical model based on VTK is researched,and realized it on PC by Microsoft Visual C++.The specific process of 3D observation and the technology of 3D interactive pickup are discussed.The system will be valuable for diagnosis and lay a good foundation for virtual surgery and tele-medicine.
