Novel method for correction of x-ray fluoroscopic image.
X-ray fluoroscopic images have been widely used in orthopedic surgery. Unfortunately, the inherent distortion deteriorates the quality of fluoroscopic image. To avoid the discontinuities of local correction techniques and achieve good accuracy in present global correction method, a novel approach for distortion correction is proposed which allows good image quality in relatively acceptable time by combining both global and local methods, and a new local interpolation method is also proposed. Computer simulation and experimental test on fluoroscopic image have been carried out.
