Homework Help: Transducer design

  1. Feb 14, 2008 #1
    1. The problem statement, all variables and given/known data

    When characterizing tissue with the pulse echo imaging method. it is important that the intensity distribution in both tjhe axial and lateral direction is as uniform as possible. what is the minimum depth in tissue you should recommend to employ for imaging purposes with your designed pulse-echo transducer?

    2. Relevant equations
    PE material is Pz-26, sounf velocity 4080 m/s.
    also there are values for the backing layer.


    3. The attempt at a solution
    Matching layer 2.9 mm of Pyrex glass. data for it also available
    Should we use that the depth is lambda/2 to get the interference to receive the doubled signal? using the lambda/4 will cause damping. as the front matching layer
