Automatic correction of rotating ultrasound bio microscopy acquisitions for the segmentation of the eye anterior segment.

Abstract

We have developed a rotating 3D probe prototype in order to acquire the anterior segment of the eye in three dimensions. The acquisition accuracy has to be sufficient to allow for the use of automatic segmentation of the provided data, and thus generate a 3D structure of the eye, for which it could be easier to obtain measurements than in 2D images. We have created an image post processing scheme in order to compensate for vibrations and eye movements during acquisition that are associated with increased noise. These tools have been applied to 92 volume datasets acquired on 21 patients in pre-operative conditions. Acquisition noise was reduced by 97% in specific conditions with respect to data acquired without correction.
