摘要:
A device and method are disclosed for detecting and correcting unintended eye movements that may occur during an ultrasound scan by monitoring multiple position tracking sensors, examples being but not limited to ultrasound or optical position sensors. These position tracking sensors are in addition to the ultrasound imaging transducer and are in a fixed position on the scan head so as not to move during the scanning operation. These position tracking sensors can continuously monitor the distance to the cornea or other clearly defined anatomical features of the eye such as the posterior pigment layer of the iris during the movement of the scan head assembly and can provide continuous multi-dimensional correction for any unwanted motion of the eye relative to the scan head that may occur during the ultrasound scan.
