    Abstract: An apparatus for calibration of a probe that includes a magnetic position sensor and an acoustic imaging device has a rigid mechanical framework. One or more field generators, fixed to the framework, generate a magnetic field of known spatial characteristics. An acoustic target assembly includes a phantom coupled to a motion mechanism, which is arranged to move the phantom in a known orbit relative to the framework. A jig, fixed to the framework, holds the probe within the magnetic field of the one or more field generators, in an orientation suitable for the imaging device to image the phantom. A processor processes position and image signals from the probe in order to calibrate coordinates of the imaging device relative to the position sensor.

    Abstract: A method for image enhancement includes performing a multi-resolution decomposition of an input image, thereby generating multi-resolution transform components associated with different image scales, comprising at least first and second image scales. A multi-resolution reconstruction is performed to generate an enhanced image by applying filter coefficients to the multi-resolution transform components, such that different, first and second filter coefficients are respectively applied to the multi-resolution transform components that are associated with the first and second image scales. The decomposition is typically performed using a forward transformation filter, and the reconstruction uses a reverse transformation filter, which is not necessarily an inverse of the forward transformation filter
