Wireless needle guidance using encoder sensor and encoder scale to achieve positional sensing between movable components

Abstract

One or more devices, systems, methods and storage mediums for performing medical procedure (e.g., needle guidance, ablation, biopsy, etc.) planning and/or performance, and/or for performing guidance of multiple probes or multiple needles, are provided. Examples of applications for such devices, systems, methods and storage mediums include imaging, evaluating and diagnosing biological objects, such as, but not limited to, lesions and tumors, and such devices, systems, methods and storage mediums may be used for radiotherapy applications (e.g., to determine whether to place seed(s) for radiotherapy). Even in instances where communication between a medical tool or needle guidance device and a system is wireless or wired, preferably guidance information is still gathered and transmitted, especially in instances where wireless or wired communication signals are intermittent or interrupted.
