METHOD AND DEVICE FOR DETERMINING THE LOCATION OF AN ENDOSCOPE

A technician-free strategy enables real-time guidance of bronchoscopy. The approach uses measurements of the bronchoscope's movement to predict its position in 3D virtual space. To achieve this, a bronchoscope model, defining the device's shape in the airway tree to a given point p, provid...

Zusammenfassung:	A technician-free strategy enables real-time guidance of bronchoscopy. The approach uses measurements of the bronchoscope's movement to predict its position in 3D virtual space. To achieve this, a bronchoscope model, defining the device's shape in the airway tree to a given point p, provides an insertion depth to p. In real time, the invention compares an observed bronchoscope insertion depth and roll angle, measured by an optical sensor, to precalculated insertion depths along a predefined route in the virtual airway tree to predict a bronchoscope's location and orientation.
