Delay Quantization Error in Phased Array Images

Journal Article (Journal Article)

Time quantization errors in phased array systems can cause increased sidelobe amplitude, thereby limiting the dynamic range of the ultrasound system. A simulation program predicting the position and amplitude of these anomalous quantization error grating lobes has been developed to study the effects of transmitted pulse length on the amplitude of these anomalous lobes. Three parallel processing techniques for decreasing these sidelobe amplitudes while smoothing the speckle pattern are investigated. © 1981 IEEE
