Ultrasound B-mode imaging provides anatomical images of the body with a high resolution and frame rate. Recently, to improve its flexibility, most ultrasound signal and image processing modules in modern ultrasound B-mode imaging systems have been implemented in software. In a software-based B-mode imaging system, an efficient processing technique for calculating a logarithm instruction is required to support its high computational burden. In this paper, we present a new method to efficiently implement a logarithm operation based on exponent bit extraction. In the proposed method, the exponent bit field is first extracted and then some algebraic operations are applied to improve its precision. To evaluate the performance of the proposed method, the peak signal-to-noise ratio (PSNR) and the execution time were measured. The proposed efficient logarithm operation method substantially reduced the execution time, i.e., eight times, compared to direct computation while providing a PSNR of over 50 dB. These results indicate that the proposed efficient logarithm computation method can be used for lowering the computational burden in software-based ultrasound B-mode ultrasound imaging systems while improving or maintaining the image quality.

Abstract-In commercial ultrasound systems, the multielement transducer array is connected to analog front end electronics using long-wire high voltage coaxial cables. This paper presents the circuit design of 16-channel Transmit (Tx) and Receive (Rx) beamforming ASIC (Application Specific Integrated Circuit) that can be integrated in ultrasound probe head which reduces the number of coaxial cables. The proposed modular design for programmable 16-channel transmit beamformer operates at medical frequencies in pulse-echo mode and provides user control of transmit parameters such as transmit pulse length, pulse pattern, transmit frequency, and mode of excitation. The receive beamformer implements delay and coherent sum of the digitized echoes from 16 adjacent transducer elements to form scanlines required for image reconstruction. The proposed architecture of the Rx beamformer design provides great flexibility for beamforming, such as receive focusing with predetermined delay profile. Each transmit channel can be programmable to give a maximum delay of 163.85 µs with 1.25 ns delay resolution. The proposed design implements dynamic receive focusing with minimum time delay resolution of 3.125 ns for 40 MHz input data rate. The proposed ASIC of integrated Tx and Rx beamformer is implemented in UMC 130 nm technology using Synopsys ICC and Design Compiler. The implementation reports show that the area is 5.29 mm 2 , power dissipation is 38 mW.
