Abstract
The filter coefficients (impulse response) are first determined using Matching Pursuit (MP) algorithms. Additionally, the MP algorithms are made recursive to enable online filtering of the data. The inner diameter of the CCA was calculated for twenty seven subjects using the reconstructed (filtered) data. The estimated diameters were compared with diameters obtained from a B-mode imaging system and was found to be in close match. Furthermore, it is found that for a subject, only the non-zero impulse responses and their sample numbers need to be stored to recover the filtered echoes. Leading to a significant data compression.
