Patient-specific Model Generation using Multiview 3D Reconstruction for Hyperthermia Treatment Planning

Hyperthermia treatment of locally advanced mouth and oral cancers requires three-dimensional model of the patient, mostly emphasizing nasal throat region for treatment planning. 3D patient-specific model is crucial to plan the procedure for effective and localized thermal therapy. An image-based reconstruction technique, structure from motion (SfM) is a cost effective, flexible and efficient solution for this end application. Although SfM provides various algorithms and pipelines, it is important to select the optimum image capturing technique and effective pipeline to obtain robust 3D image reconstruction. In this work, we present the evaluation and analysis of effective hand-held image capturing techniques and performance of few open-source reconstruction pipelines tested on custom synthetic and real world captured data.
