Abstract:With the known limitations of 2D medical imaging systems currently used in clinics, the increase in development and availability of 3D scanners and images can address these shortcomings. Current 2D photography systems include MRIs, X-rays, CTs, and ultrasounds, which provide information about the internal mechanisms of the human body. However, none of these devices are able to provide quantitative images of the complex surface of the human body. This is important for monitoring the development of bodily changes, measuring surface area of skin ailments, and planning or demonstrating surgical techniques. The first experimental aspect of this research is to examine the ability of the iPhone X to make a 3D scan, since this is a novel device which has yet to be used in the clinical setting, but has shown the potential in being more accurate. The second focus of this study will be to determine the main steps needed to successfully process a 3D scan for quantitative measurements. The goal is that the steps can be applied seamlessly to any necessary application while maintaining accuracy. This paper will primarily target the application of 3D scanning the breast and obtaining volume measurements. This particular application is helpful in monitoring breast development for transgender studies and breast reconstruction. Breast phantom scans were shared for this study from the Department of Internal Medicine at the Amsterdam UMC. In this project, 3D scans were obtained using the iPhone XR, and a workflow was defined for processing the scan that can be used to gather accurate volume measurements for future clinical applications. While the general steps have been detailed, achieving accuracy depends on the shape complexity of the object and the experience of the operator.
