Methods for diagnosing vitreo-retinal disease

摘要

A quantitative method to analyze phase-resolved, raw backscatter echo data or the envelope of phase-resolved, raw backscatter echo data to characterize vitreous inhomogeneities as they relate to normal aging and vitreo-retinal disease. The technique can be applied to 2D or 3D data acquired from the vitreous. The approach provides an objective end value to characterize the vitreous and provide a tool for early diagnosis, monitoring and planning treatment of vitreo-retinal diseases.

1. A method to acquire and process vitreous image data to characterize vitreous inhomogeneities comprising the steps of:
creating a unit, said creating a unit comprising transmitting at least one ultrasound signal, acquiring phase-resolved, raw backscatter echo data of said transmitted signal, and normalizing said acquired data, wherein said normalized acquired data forms said unit; the method further comprising: extracting local level estimates from said normalized data; and processing said extracted local level estimates, said processing producing at least one global parameter, said at least one global parameter being used to objectively characterize one or more vitreous inhomogeneities.
