Exemplary embodiments of the present invention are directed to the complete and total prevention of galvanic coupling in humans and animals. This is accomplished by placement of an electrical insulator between: (1) a bone-metal implant interface and conductive bodily fluid; (2) a bone-conductive fluids interface and a metal implant; and (3) a metal implant-conductive fluids interface and bone.

This application discloses an image quality assessment method, apparatus, and electronic device. The method includes: acquiring raw image data of a target object; determining the geometric centroid of a metal implant from the raw image data; dividing the human mask region corresponding to the target object in the raw image data into multiple sub-regions by extending multiple rays radially from the geometric centroid; determining statistical indicators for each sub-region; and determining the quality assessment result of the raw image data based on the statistical indicators. This application solves the technical problem of traditional assessment methods that uniformly process all pixels in the entire medical image, easily leading to confusion between radial artifacts produced by metal and statistical fluctuations generated by normal high-density bone structures, resulting in inaccurate assessment results.
