Abstract:
Crystal centering is a key step in macromolecular X-ray crystallography experiments. A new method using image-processing and machine-vision techniques allows the centering of small crystals in the X-ray beam. This method positions crystals even when the loop is initially out of the camera's field of view and adapts to the difficulty of the experiment. The process has been tested on many diverse crystals with a 93% success rate when compared with manual centering.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
