* BASICS:

                                   Physics, Instrumentation, Standardization, State of the Art in Software, Automation

 
            * Examination Techniques:

       A-scan (8 MHz) < posterior & anterior eye segments, orbit & periorbital region >

      B-scan (10 MHz, 20 MHz) < posterior eye segment, anterior orbit >
