Null subtraction imaging technique for biomedical ultrasound imaging
In ultrasonic imaging, reduction of lateral sidelobes results in an improved image with less distortion and fewer artifacts. In general, apodization is used to lower sidelobes in exchange for increasing the width of the mainlobe and thus decreasing lateral resolution. Null subtraction imaging (NSI) …

Evaluation of null subtraction imaging and interpolation techniques for ultrasound B-mode
In biomedical ultrasound imaging, many attempts have been made to improve the lateral resolution through various adaptive and non-adaptive techniques. While each technique has its advantages and disadvantages, there are some challenges common to all methods. In particular, improvements in lateral …
