摘要： Methods and associated apparatuses for imaging a target. An echo sequence image of the target is acquired (10) and a log spectrum of at least a portion of the echo sequence image is computed. A point spread function is estimated (14) by one of two methods. According to the first method, a low-resolution wavelet projection of the echo sequence log spectrum (22) is used as an estimate of the log spectrum of the point-spread function. According to the second method, an outlier-resistant wavelet transform of the echo sequence log spectrum is effected (44), followed by soft-thresholding (46) and an inverse wavelet transform (48). Under both methods, a frequency domain phase of the point spread function also is estimated. The relevant portion of the echo sequence image is deconvolved using the estimated point spread function.
