Solid state X-ray detectors based on large-area amorphous semiconductors such as amorphous silicon or selenium have been developed. The requirements for various applications in medical diagnosis determine the boundary conditions for different detectors. Key parameters are image receptor size, spatial resolution, image frequency, signal-to-noise ratio, and long-term stability. Conventional thora...
Image entropy as prior in Bayesian inference was applied to the restoration of X-ray digital images with additive zero mean Gaussian distributed noise. An iterative algorithm based on a conjugate gradient method with numerical evaluation of partial derivatives was developed to efficiently minimize the potential function associated to any positive, additive distribution. The correlation matrix o...
Fragile X syndrome (FXS) is the most common known genetic cause of inherited intellectual disability and the most common known single-gene cause of autism spectrum disorder. It has been reported that a spectrum of medical problems are commonly experienced by people with FXS, such as otitis media, seizures, and gastrointestinal problems. Previous studies examining the prevalence of medical probl...
