[Quality assurance for diagnostic ultrasonic equipment in A- and B-mode in ophthalmology (author's transl)].

Quality assurance for diagnostic ultrasound in ophthalmology is of growing importance and will be the subject of new standards and regulations. Methods for equipment performance testing by means of electric test signals in A- and B-mode equipment are described, both for comparative evaluation of equipment and for routine quality assurance tests. Newly developed test signal generator for checking the time scale in ultrasonic biometry of the eye are presented.
