There is a Calculator of delays for ultrasonic phased arrays called HaroUT that is now available for free on the LabVIEW Tool Network.
I have created a document to describe the operation of the application in Document 47128.
By the same token, I have created an Ultrasonic group. Join if you are interested by LabVIEW developments and techniques related to ultrasound for NDT or medical applications.
