An ultrasound probe calibration system and method. The system comprises an ultrasound probe calibration phantom (), and the ultrasound probe calibration phantom () is provided with a sunken recess () at a middle position of an upper surface thereof and with several conical holes on a side surface thereof. The sunken recess () is fixedly connected with a two dimensional ultrasound probe () therein. The conical hole is inserted with an NDI insertion stylus (), and a tip of the NDI insertion stylus () can be acquired in ultrasound imaging. An ultrasound probe calibration system employing the above structure enables a midplane of an ultrasound plane to pass a midplane of an ultrasound probe calibration phantom () along a middle gap, such that a tip of an NDI insertion stylus () is used for the midplane of the ultrasound plane, thereby addressing the problem of misalignment of a point-type phantom or a two-dimensional plane-type phantom to the ultrasound plane.

The examples of the present invention disclose a method for dynamically linking a program on an embedded platform and an embedded platform. The embedded platform includes a middle layer which comprises at least one class. An application program to be linked includes at least one class. The application program is compiled into PICs, wherein storage positions of different code sections in the PICs which are obtained by compiling different functions of the application program do not overlap with each other; all the PICs are copied into a memory of the embedded operation system; a class pointer is created, and the class pointer is transferred between the class of the middle layer and the class of the application program to dynamically link the application program.

Method for dynamically linking program on embedded platform and embedded platform

Automated image quality assessment algorithms, which perform the functions of locating a region of interest, maximizing the image contrast, and ensuring the region of interest is properly centered in the image. Wherein the region of interest is located by spectral matching filter using a target spectrum obtained from samples of the image itself.

Method to provide automated quality feedback to imaging devices to achieve standardized imaging data

Automated image quality assessment methods, which include locating a region of interest, region assessment, contrast assessment, blur assessment, and contaminant detection, on video data and high-resolution imagery. Where the blur assessment is performed without a reference image by dividing the region into non-overlapping block, measuring the wavenumber frequency of the blocks and calculating the ratio of the low frequency to high frequency areas.
