Designed especially for use with endoscopes and laproscopes. Now available for beta testing. It lets you accurately track the spatial location of probes, instruments, and other devices. With dimensions of just 18mm x 8mm x 8mm for the Model 800 and just 10mm x 5mm x 5mm for the Model 500, each sensor is small enough for both external and internal use. DC magnetic fields overcome blocking and distortion DC magnetic fields avoid blocking problems and yield reduced distortion from nearby conductive metals.
Signals pass through the human body without attenuation.
Mini sensors may be inserted into a body cavity to accurately record instantaneous position and orientation. In one major new application, its sensors continuously monitor the descent of the fetal head during human labor to optimize outcome while minimizing C-sections. Dual mini sensors are used for differential readings of anatomical structures and for tracking multiple instruments. These approaches provide accurate volume measurements and precise navigation inside the body. For example, miniBIRD ensures that biopsy needles reach their target by correlating needle orientation with ultrasound imagery.
