Ive been given some formulas that I need to follow for the computing the ultrasound output levels computation from a imaging tranducer, its required by the FDA
I have to integrate the power (h)(measured from hydrophone)from the face of the transducer in the x and y direction.
the formula is something to the extent
v(z) = 1/T * integral (integral ( h (x,y,z) ) dx dy
now if im using sample points for h(x,y,z), its really a summation rather than integral.
so the question.
If the sample points of the hydrophone voltage were taken at 0.25mm steps, not 1cm
and the units of constant T are in CM.
do I have to correct for this by using a scalar?
thanks for the help in advance
