The B-scan technique consists of focused, short-wavelengths and an echographic probe that converts electrical energy into mechanical energy. A-scan ultrasound biometry, commonly referred to as an A-scan (short for Amplitude scan), is a routine type of diagnostic test used in optometry or ophthalmology. The A-scan provides data on the length of the eye , which is a major determinant in common sight disorders . B-Scan.
