Abstract

The problems in the ultrasonographic examination are discussed in four categories as follows; 1) Problems arising from the characteristics of the ultrasonographic equipment such as limited field of view, poor resolution in the far field, dead space in examination of the liver, etc. 2) Problems related to the operation of the equipment such as optimizing the gain, STC, dynamic range, and selection of the focal depth and dynamic focus technique. 3) Problem concerning the interpretation of the ultrasonic images such as determining the orientation of the organ displayed on the image, intra-observer divergence in interpretation of the ultrasonogram. 4) Financial problems about ultrasonography.
