Purpose: Although the thermoplastic immobilization tool is used to efficiently control of patient movement, movement of the patient’s skin surface under thermoplastic immobilization tool exists. In addition, thermoplastic immobilization tool is used as a method of covering the skin surface, which makes it difficult to visually check the skin surface movement. Therefore, the aim of this study is to develop an IR marker that visually checks the movement of the patient’s skin surface even used the thermoplastic immobilization tool.
Methods: The structure of IR marker was consisting of a spherical IR marker, a cylindrical marker and a disk-shaped marker base. The disk-shaped marker base has a number of holes to be combined with cylindrical marker posts. The design of this disk-shaped marker base allows the IR marker to be located on skin surface without interference with thermoplastic immobilization tool. Confirmation of developed IR marker is performed by locating the IR marker on the skin surface along with the thermoplastic immobilization tool. We also developed the IR marker motion checking program. Using this program and IR marker, the movement of the skin surface under the thermoplastic immobilization tool is checked.
Results: The IR marker was developed for thermoplastic immobilization tool. When the IR markers were located on the skin surface along with thermoplastic immobilization tool, we confirmed that it is well located on without any other problems. And we confirmed that the IR marker motion checking program detects the movement of IR marker well. However, experiments that check the movement of the skin surface were still underway, therefore no results were obtained.
Conclusion: We have developed the IR marker for thermoplastic immobilization tool. The developed IR marker was confirmed to be suitable for our purpose. Further study, we will verify that the developed IR marker detects movement of the skin surface.
