An Miniature Indirect Conversion X-ray Detector with Efficient Noise Filtering Techniques

An indirect conversion X-ray detector with input optics based on a fiber optic taper (FOT) and a CMOS camera has been developed. The detector is intended for use in high resolution X-ray diagnostics with microfocus X-ray tubes. A new technique for eliminating impulse noise is proposed. The efficiency of the technique is shown in comparison with other known filtering methods with respect to the degree of noise suppression and the preservation of fine image details. In-house software for processing X-ray images was developed: an image capture module and the impulse noise filtering algorithm were implemented.
