Shape-Sensing
Without intraoperative CT imaging, the shape-sensing technology employed by Ion can be off by at least 1cm 47% of the time in the upper lobes and 82% of the time in the lower lobes.¹ A recent study demonstrated that, without intraoperative CT imaging, Ion was only able to achieve a diagnostic yield statistically indistinguishable from superDimension’s EMN-based system.²
