  • Method and system of providing visual information about a location and shape of a tumour under a body surface of a human or animal body
    Patent number: 11523869
    Abstract: In a method and system for providing visual information about a tumour location in human or animal body, an electromagnetic tumour sensor is provided in the tumour and tracked to determine its location in space, which is mapped to a tumour model. A surgical tool sensor is provided on a surgical tool, and tracked to determine its location in space, which is mapped to a surgical tool model. The body is scanned to obtain information about an anatomical structure. A reference sensor is provided on the body, and tracked to determine its location in space, which is mapped to the anatomical structure. A virtual image is displayed showing the tumour model, located with the at least one tumour sensor, in spatial relationship to the surgical tool model, located with the at least one surgical tool sensor, and the anatomical structure, located with the at least one reference sensor.
