Gain determination of feedback force for an ultrasound scanning robot using genetic algorithm.

abstract：PURPOSE:C-arms are portable X-ray devices used to generate radiographic images in orthopedic surgical procedures. Evidence suggests that scouting images, which are used to aid in C-arm positioning, result in increased operation time and excess radiation exposure. C-arms are also primarily used qualitatively to view ima...
