Abstract

Scaling is a part of geometric transformation. Scaling transformation used to change the size of the object either to shrink or to enlarge. Object scaling typically used in computer graphics. This paper discusses the techniques and algorithms that can solve the problem of scaling in the medical field that involves the use of medical images and digital implants. In the medical field, scaling techniques are used by the surgeon during the pre-surgery. For manual template method, the surgeon facing two different magnified image scales such as the x-ray scale and the implant (template) scale. To match the digital implant (600dpi) and x-ray images with the computer screen, the ratio of digital implants with the x-ray images of patients generated using the resolution information and x-ray images pixel density. The ratio is then used in magnification algorithm for image enlargement and miniaturization. The results showed that digital implant hip joint can be accurately scaled using scaling techniques shown in this paper. In addition, by using digital implant with high resolution, x-ray images enlargement can be up to a 100% without affecting the image of the implant.
