Electromagnetic field detecting method for e.g. digital radiography imaging system, involves measuring electromagnetic field using detector of digital imaging system, and reading field image from detector based on electromagnetic field
Electromagnetic field detecting method for e.g. digital radiography imaging system, involves measuring electromagnetic field using detector of digital imaging system, and reading field image from detector based on electromagnetic field
The method involves emitting an electromagnetic field (160) by an electromagnetic emitter (150) of a surgical navigation system. The electromagnetic field is measured using a detector (120) e.g. flat panel amorphous silicon X-ray, of a digital imaging system (100), where the detector reads an image of an object (140) and a field image. The field image from the detector is read based on the electromagnetic field. The field image read from the detector is processed by an image processing unit (130). A position of an element e.g. surgical tool, is determined based on the electromagnetic field.
