System for automated positioning of operating tables using ultra-wideband localization and patient-specific anatomical data

Abstract

A system for the automated positioning of operating tables using ultra-wideband localization and patient-specific anatomical data, wherein the system comprises: a plurality of ultra-wideband anchor units arranged in a predefined spatial configuration within an operating environment and configured to transmit and receive ultra-wideband signals; at least one ultra-wideband tag unit configured to be associated with a patient or patient support structure of an operating table; a localization processor configured to determine in real time the three-dimensional coordinates of the ultra-wideband tag unit relative to the ultra-wideband anchor units based on time-of-flight measurements of the ultra-wideband signals;a data acquisition processor configured to receive patient-specific anatomical data obtained from preoperative imaging procedures; an anatomical processing processor configured to generate a three-dimensional anatomical representation and create a patient-specific coordinate reference; a coordinate transformation processor configured to spatially align the real-time coordinates obtained from the localization processor with the patient-specific coordinate reference; a positioning calculation processor configured to determine the necessary positional adjustments of the operating table with respect to translational and rotational movements; a control processor configured to generate actuation control signals based on the determined positional adjustments;and an operating table with a multitude of electromechanical actuator units configured to perform multi-axis movements in response to actuator control signals, the system being configured to automatically align the patient relative to a predefined surgical target.
