Résumé
Les auteurs décrivent en détail la réalisation d'un vélocimètre pulsé à 20 MHz. Ce choix de la fréquence d'émission des ultrasons permet une résolution longitudinale et transversale de plus ou moins 0·15 mm. Diverses applicationsin vitro, puis chez l'animal et chez l'homme justifient le développement de ce type d'appareil, tant en microchirurgie que pour des études hémodynamiques précises.
Abstract
The writers give a detailed description of the execution of a 20 MHz pulsed Doppler velocimeter. This choice of ultrasonic emission frequency gives axial and lateral resolution of ±0·15 mm. Various applicationsin vitro and in animal and man justify the development of this type of equipment, both for microsurgery and precision haemodynamic studies.
