In 1944, Paul-Alexandre Osterrieth , who had worked as a research assistant under André Rey at the University of Geneva, utilized the figure Rey had developed in his work with young children. [6] Osterrieth proposed to subcategorize the figure into 18 elements and score them based on their presence, completeness, and correct placement.
Phased array is widely used for nondestructive testing (NDT) in several industrial sectors, such as construction, pipelines, and power generation.This method is an advanced NDT method that is used to detect discontinuities i.e. cracks or flaws and thereby determine component quality.
Making a radiograph. Industrial radiography is a modality of non-destructive testing that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures.
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
While the equations above are well defined for real-valued variables only if , i.e. if the ray is not parallel to any of the coordinate axes, the algorithm can be applied to an extended real number arithmetic (such as the one implemented by IEEE 754) to handle rays parallel to an axis, as long as the origin of the ray itself does not lie on one ...

A radiation source is positioned behind the patient at a standard distance (most often 6 feet, 1,8m), and the x-ray beam is fired toward the patient. In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect of the chest.
