Strategies in Doppler ultrasound.

A computer based system integrating a continuous wave 10 MHz Doppler ultrasound system with a standardising electrocardiographic record has been developed and tested. Data storage and duplication are intrinsic elements in the system which also includes on line analysis of the data. The electrocardiograph permits exact timing and standardisation of the pulse wave forms. The results can be displayed and printed. The controlled data provides a valid basis for comparison. Data obtained from patients suffering from amaurosis fugax are presented and discussed.
