US 2026/0213007 A1 · TRACKING SYSTEM AND METHOD FOR PATIENT TRANSFER DURING IMAGING AND TREATMENT PROCEDURES

Abstract

A system supports a patient and tracks the position and/or orientation of a patient support. The system has a patient transfer apparatus; at least one reference surface; a sensor acquiring input related to a position of the patient transfer apparatus; at least one processor to process and convert the input from the at least one sensor; at least one transmitter to transmit the input from the at least one sensor to the at least one processor; and a tracking feature disposed on the reference surface. The sensor is coupled to the patient transfer apparatus to detect the tracking feature disposed in or on the at least one reference surface and the at least one transmitter transmits the input from the sensor to the at least one processor for processing and conversion into coordinates within a reference frame in at least one degree of freedom.

Dependent claims

A system configured to support a patient and track the position and/or orientation of a patient support, the system comprising:

a patient transfer apparatus configured to support and transfer a body of the patient;
at least one reference surface;
a sensor capable of acquiring input related to the position of the patient transfer apparatus;
at least one processor configured to process and convert the input from the at least one sensor;
at least one transmitter configured to transmit the input from the at least one sensor to the at least one processor;
a tracking feature disposed on the reference surface and having at least one encoding index adapted to be detected by the at least one sensor, and further representing a unique position within the reference surface;
and
wherein the sensor is coupled to the patient transfer apparatus, such that the sensor is positioned to detect the tracking feature disposed in or on the at least one reference surface, and
wherein the sensor is connected to the at least one transmitter, and
wherein the at least one transmitter is connected to the at least one processor, such that the at least one transmitter is capable of transmitting the input from the sensor to the at least one processor for processing and conversion into coordinates within a reference frame in at least one degree of freedom.

A method of determining the coordinates of a patient transfer apparatus within a reference frame, the method comprising the following steps:

(a) positioning at least one sensor coupled to the patient transfer apparatus, such that the at least one sensor is capable of detecting at least one tracking feature positioned within the at least one reference surface;
(b) activating the at least one sensor, such that it is capable of acquiring input, the input including the at least one tracking feature disposed in the at least one reference surface and the at least one tracking feature represents a unique position defined in the at least one reference surface;
(c) acquiring, using the at least one sensor, input, the input including the at least one tracking feature disposed in the at least one reference surface, the at least one tracking feature representing a unique position within the at least one reference surface;
(d) transmitting, using the at least one transmitter, the input from the at least one sensor to at least one processor;
(e) interpreting, using the at least one processor, the input from the at least one sensor, including converting selected structures of the at least one tracking feature into coordinates within the reference frame;
and (f) transmitting output, the output including coordinates within the reference frame to another unit comprising a display.
