Chemiluminescent Western blotting is a popular protein detection method for studying proteins. The typical protocol for measuring chemiluminescent signal exposes the Western blot to laboratory-grade X-ray film, but digital imaging using a cooled-CCD camera is proving to be a more functional choice for researchers. The Thermo Scientific MYECL Imager offers digital imaging with a number of improv...

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...

A new digital signal processor (DSP)-based data acquisition system has been designed and installed at the Advanced Photon Source. This system uses a commercial VME-based DSP card to acquire and process x-ray blade signals to determine x-ray beam position for both bending magnet and insertion device beamlines. The system also acquires and processes position data from the narrowband rf BPMs that ...

We demonstrate a new technique for selectively growing gold nanoparticles on a patterned three-dimensional (3D) polymer microstructure. The technique integrates 3D direct writing of heterogeneous microstructures with nanoparticle synthesis. A digital micromirror device is employed as a dynamic mask in the digital projection photopolymerization process to build the heterogeneous microstructure l...

Aim To compare digital images of conventional radiographs with the original radiographs for perceived clarity of periapical lesions and the quality of root canal treatment. Materials and Methods One hundred and four intraoral periapical radiographs of patients with endodontically treated teeth were randomly selected. The radiographs were digitized using an MD300 USB X-ray Reader. The digital ...
