Abstract

Ultrasound is a popular imaging technique mainly due to its non-invasive nature. And so, it is being used in a variety of applications. Due to plane wave imaging technique in ultrasound, frame rate of ultrasound imaging has the potential for being very high. Due to which, many channel data frames are being generated within a few seconds. As a result, tasks such as storing data frames and transferring them from front end ultrasonic system to processing computers are presenting significant challenges. Our current research work minimized these issues. We proposed and implemented: (a) Data encoding technique - We combined every two consecutive raw channel data frames without repetition in full data to generate a reduced version of raw data, whose size is half of original data in the front end, (b) Data compression technique – We applied discrete frequency domain transforms on full raw data, all frequency components less than or equal to median value are discarded. Both (a) and (b) reduced data storage requirements by up to 50%. Furthermore, transferring this reduced data into the computer increased the data transfer efficiency by approximately 50%, when compared to full data transfer. Data decoding and inverse frequency-domain transforms were performed in the computer software, followed by the ultrasound image reconstruction process. The final technique (c), which integrated both (a) and (b), achieved an overall data reduction of up to 75%. All these improvements were made with only a slight increase in the computer’s processing time. Finally, the performance of our proposed methods was evaluated using several quantitative metrics such as SSIM, MSE, PSNR, mean, standard deviation, image sharpness, and variations in image brightness and contrast. From which, it was clear that our final images are in close resemblance to ground truth images.
