Pseudo-inverse filter design for improving the axial resolution of ultrasound images

The resolution of medical ultrasound systems can be improved using filtering techniques. We present a filter for improving the axial resolution that approximates an inverse filter but which is less sensitive to noise than a standard inverse filter making it suitable for use with ultrasound. This fil...

Description
Summary:The resolution of medical ultrasound systems can be improved using filtering techniques. We present a filter for improving the axial resolution that approximates an inverse filter but which is less sensitive to noise than a standard inverse filter making it suitable for use with ultrasound. This filter produces a superior image resolution to that gained by matched filtering, and also shows advantages over a Wiener optimal filter, and other filters presented in literature.
