Abstract
At present time the ultrasound imaging technique is widely used for qualitative evaluation of ocular tissue structure. Differential diagnosis of human eye tumors is one of the most important problems in ophthalmology in dealing with cancer prevention and diagnostics. Simple ultrasonic methods such as A scan and B scan images used in ophthalmology helps to identify intraocular tumors, but does not reflect the microstructure, does not allow them to differentiate. New technique for tumors tissue structure evaluation using ultrasound spectral analysis is presented. Based on the obtained results, it can be said that RF ultrasound signals parameters (amplitude envelope, spectrum slope, spectrum intercept and momentary bandwidth) at the healthy tissue area and the area with the intraocular tumor – melanoma and hemangioma statistically are significantly different. This allows us to distinguish healthy tissues from the abnormal tumor tissues, to identify and differentiate chorioidal melanoma and hemangioma between each other.
