Geometric Transformation Technique for Total Hip Implant in Digital Medical Images

The use of geometric transformation is extremely crucial in the medical field because it can assist surgeons in carrying out pre-surgery process effectively and properly. This study aims to produce techniques and algorithms that can be used to implement the implant transformation process such as rotation and reflection on medical images. The main objective of this paper is to show the hip joint implant transformation algorithm used in x-ray images of hip joint patients. The computerised hip joint replacement process developed by a group of researchers from the Industrial Computing Research Group, Faculty of Technology and Information Science, Universiti Kebangsaan Malaysia shows how the implant transformation process being perform. The code of two transformation algorithms (rotation and reflection transformation) were shown in this paper. The example showed that by using the suggested transformation, the position of the hip joint implant can be manipulated to obtain the optimal position on the x-ray images of patients.
