    摘要: Systems, methods, and devices for registering a 3D image of a patient with magnetic coordinates are disclosed. A tri-axial sensor (TAS) may be added to the 3D camera. The location and orientation of the TAS sensor may be determined based on the known magnetic fields that are applied by a magnetic field transmitter. The camera coordinate system may then be transferred to the magnetic coordinate system. After completing the registration of the 3D image with a CT image and the 3D image with the magnetic coordinates, the CT image may then be registered with the magnetic coordinates.

    摘要: Apparatus, including a probe having a distal end insertable into a nasal sinus of a human patient, and a location sensor positioned within the distal end. A sinuplasty balloon is positioned on the distal end at a selected opening of the nasal sinus. A processor receives first signals from the location sensor while the distal end is inserted into the nasal sinus and prior to positioning of the balloon at the selected opening, and generates a first map of the sinus. The processor inflates the balloon when it is at the selected opening, so as to enlarge the selected opening, and subsequently deflates the balloon. The processor then receives second signals from the location sensor and generates therefrom a second map of the sinus. The processor registers the first map with the second map and generates from the registered maps a numerical increase in size of the selected opening.
