An efficient real time focusing delay calculation in ultrasonic imaging systems.
An efficient real time focusing delay calculation algorithm is proposed for variable sampling clock generation (SCG) with high accuracy needed in digital focusing in ultrasonic imaging systems. The proposed algorithm is an extension of the midpoint drawing algorithm that is well known in the computer graphics area. It can be implemented with simple hardware amenable to VLSI realization, without using a large amount of look-up memory to store the sampling clock information otherwise required.
