碩士 === 國立臺北科技大學 === 機電整合研究所 === 100 === The Ultrasonic Image (Ultrasonography) Guided Medical Injection has been widely used as a medical treatment in Orthopedics and Neurology. However, the medical ultrasonography can only scan the sectional profile of patients’ infected area. Moreover, it usually requires the doctors’ experience to inject medicine accurately into the patients’ infected area during the image guided injection process. Therefore, the purpose of this research is to design and implement an ultrasonic image guided medical injection training system. This system can simulate the ultrasonic image guided medical injection process in virtual reality and provides an interactive training with the virtual images and equipment operation. With this virtual reality training simulation, doctors can thoroughly understands the spatial relationship between ultrasonic sectional image and needles of syringe. This research integrates the software of virtual reality and the spatial location of sensors. Two spatial location sensors are used separately in simulated mechanisms of ultrasonic probes and needles. On the other hand, the research develops the transformation of the fixed coordinates and the body coordinates of each sensor so that the training platform will not be restricted by the fixed coordinates. It also uses the 3D software to construct the ultrasonic image modules for training simulation. With these volume image files, this system can produce the sectional profiles to mimic the function of ultrasonic probes. With the Geometric Analysis algorithms developed in this research, the interaction of the ultrasonic sectional profile and the needles can be calculated and displayed on the image. A calculated needle-cross-section on the profile will be sized and oriented, which makes the simulating image resemble the real one vividly. The simulation training system developed in this research can make the ultrasonic image guided medical injection training easier and more efficient. It will help doctors to enhance their skills and reduce the malpractices of treatment in the real-world medical operations.
