Abstract
We propose a bed-type non-invasive ultrasound theragnostic system that tracks movements of an affected area (kidney stone / tumor, in this study) by irradiating it with high-intensity focused ultrasound (HIFU). In this paper, the concept behind a medical support system that integrates therapy and diagnostics (theragnostics), is illustrated. The required functions for the proposed system are discussed and an overview of the constructed system configuration is illustrated. Problems of extracting, tracking, monitoring the affected area by ultrasonography are described. To overcome with this problem, we propose a bed-type servoing system for body targets, which make it easy to set a proper ROI and acquire proper template model to track and follow the targets.
