Abstract

Procédé d'examen d'un patient combinant les techniques de tomodensitométrie et d'ultra-sons. Le procédé de l'invention consiste à déterminer les valeurs de la vitesse de propagation des ultra-sons dans la section déterminée, à partir des valeurs de la densité dans cette section données par la tomodensitométrie et des valeurs de l'impédance acoustique dans cette même section données par un système émetteur-récepteur d'ultra-sons. Ce procédé permet d'améliorer la qualité de l'examen et la sûreté du diagnosticA method of examining a patient combining the techniques of computed tomography and ultrasound. The method of the invention consists in determining the values of the speed of propagation of ultrasound in the determined section, from the values of the density in this section given by the tomodensitometry and of the values of the acoustic impedance in this same section. section given by an ultrasound transceiver system. This process improves the quality of the examination and the reliability of the diagnosis.
