Abstract
Visualization has becoming a powerful assistive technology for neurosurgery. This paper introduces a system for stereotactic neurosurgical planning and support. Using visualization technology the system reconstructs and displays a 3D model of the interior structure of the patient's brain. Thus the surgeons can plan for surgery using a computer model. Marker registration is used to create the mapping between the patient's head and the brain model reconstructed in the computer. During the operation a robot arm is used as a navigator to locate the pre-defined incision site and the orientation of incision route. When the robot arm locates at the pre-defined site on the patient's head, it is fixed. Various medical instruments can be installed on the tip of the robot arm. The surgeon can insert a medical instrument into the pre-defined site of the patient's head, and the surgery can be implemented successfully with the help of this system. Using a virtual environment his system can also be used to teach and train new surgeons.
Highlights
With the rapid progress of computer hardware and software, visualization technology is becoming a powerful method to view the data of scientific computing, including measured data in the medical field
New developments in volume data acquisition, such as the CT, MRI, PET, SPECT etc., provide surgeons with precise and detailed information about the patient’s inner body. With this information the patient’s 3D anatomical and pathological structures can be reconstructed using visualization technology, allowing surgeons to clearly understand the exact character of the operative site and how it relates to adjacent critical anatomical structures
Given the patient’s CT and MRI images, the system reconstructs the 3D model of the critical anatomical tissues and the pathological structure
Summary
With the rapid progress of computer hardware and software, visualization technology is becoming a powerful method to view the data of scientific computing, including measured data in the medical field. A judgement of the location of the pathological tissue depends on the surgeon’s understanding of the relation between the 2D images from the CT, MRI, etc, and the physical 3D structure of the patient’s head This method heightens the pain and risk of infection, and can lead to a longer convalescence following the surgery. When the instrument reaches the pathological tissue, surgeon can use it to remove the tissue or inject some material into the brain This method reduces patient’s pain, decreases the risk of infection, and brings the patient shorter recovery time. Philippe [9] used the 3D atlas to provide the neurosurgeon with missing information This method can make the visualization and surgery planning more convenient, but the system still uses a frame to locate the position. The robot arm is used as a navigator to direct the surgery planning, and as an instrument platform to assist surgeons to accomplish the stereotactic neurosurgery
