Document Type and Number:

Japanese Patent JP2017113560

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a method for registration of a coordinate system.SOLUTION: While a catheter that includes (i) a catheter body and (ii) a catheter shaft, which includes a sensor and is disposed inside a lumen of the catheter body, is inside the body of a subject, a coordinate system of the sensor is registered with a coordinate system of an imaging system, using (a) a calibration image, acquired by the imaging system, that shows an indication of a distal end of the catheter body and (b) a signal from the sensor, but not using any indication of the sensor shown in the calibration image. Using the registration, a visual output is generated. Other embodiments are also described.SELECTED DRAWING: Figure 1
