Abstract
A system for positioning electrodes on a patient body includes an image capturing system, a memory device, a processing system and an indicator system. The image capturing system generates an actual image of the patient body. The memory device stores a reference image, the reference image including a reference body and a reference position on the reference body. The processing system compares the actual image and the reference image and for determining an electrode position on the patient body by matching the reference position on the reference body. The indicator system indicates the electrode position on the patient body.
Claims13
System for positioning electrodes on a body of a patient, the system comprising:
- a bio-impedance electode;
- an image capturing system for generating an actual image of the patient body;
- a memory device for storing a reference image, the reference image comprising a reference body and a reference position on the reference body;
- a processing system for comparing the actual image and the reference image and for determining a position of the bio-impedance electrode on the patient body in the actual image, based on the comparison, by matching the reference position in the reference image to a corresponding position on the patient body in the actual image;
- and
- an indicator system for indicating the bio-impedance electrode position on the patient body based on the determined bio-impedance electrode position in the actual image, wherein the indicator system comprises a radiation pointer system for projecting an indicator projection image on the bio-impedance electrode position on the patient body.
Method for positioning a bio-impedance electrode on a patient body, the method comprising:
- (a) capturing an actual image of the patient body;
- (b) providing a reference image, the reference image comprising a reference body and a reference position on the reference body;
- (c) comparing the actual image and the reference image for determining a bio-impedance electrode position on the patient body in the actual image, based on comparison, by matching the reference position in the reference image to a corresponding position on the patient body in the actual image;
- and
- (d) indicating the bio-impedance electrode position on the patient body, based on the actual image, by projecting a spot of visible radiation on the patient body at the determined bio-impedance electrode position.
Method for positioning a bio-impedance electrode on a patient body, the method comprising:
- capturing an actual image of the patient body;
- providing a computer generated virtual image of a virtual reference body as a reference image, the reference image comprising a reference position for the electrode on the virtual reference body;
- Using an image-processing system to compare the actual image and the reference image for determining an actual position of the bio-impedance electrode on the patient body in the actual image by matching the reference position on the virtual reference body in the reference image;
- and
- indicating the actual position of the bio-impedance electrode on the patient body, based on the actual image, to enable accurate positioning of the bio-impedance electrode on the patient body.
