A system to produce three-dimensional computer reconstructions of ophthalmic contact B-scan ultrasound was developed and investigated.Methods:
Investigators used ocular phantoms to measure the accuracy and reproduc-ibility of linear, area, and volume measurements.Results:
In vitro calibration tests of linear and area measurements demonstrate accurate and reproducible findings throughout the imaged space. Phantom volume tests also show reasonable accuracy and reproducibility.Conclusions:
Three-dimensional ultrasonography is effective in measuring length, area, and volume in an experimental model. The in vitro accuracy and reproducibility of measure-ments warrants further investigation into the clinical utility of this method in posterior segment tumors and other posterior segment pathology.
