However, MIQA evaluates the quality of images according to how well they offer useful and effective presentation to assist with physicians in diagnosing, which is greatly different from the purposes of natural image quality assessment. In this chapter, we pre

Rather, we become able to manipulate diagrams in meaningful ways once we are familiar with some specific practice, and therefore we engage ourselves in a form of reasoning that is stable because it is shared. This reasoning constitutes at the

Three dimensional ultrasonography of ocular regionolution and that the cross-sectional image of any specified plane can be reconstructed. The system consists of a 3D-Scanning unit, an image processing unit with memories of 2M bytes, and a ultrasound puiser and receiver unit. The obtained 3D-data are stored on a floppy disk or directly in the large

An equipment check program was developed which can be applied by trained technicians under hospital conditions. It provides comparable data which can be prese

Ultrasonographic observations of ocular wallsribution in the ocular walls for the basic studies of measuring the thickness of retina, choroid and sclera. Recording of the stable radiofrequency signals necessary for analysis was attained by separating the head-rest from the body bed to minimize irregular movements of the wave from various origi

The density of the scatterers is revealed by the texture up to a limit set by the transducer characteristics. For ophthalmic transducers this limit is still far above the cellul

The results suggest strongly the necessity of standardization in kinetic ultrasonography. To get to the final goal further improvement is need
