High Power Lasers produce an intense burst of Bremmstrahlung radiation which has potential applications in broadband x-ray radiography. Since the radiation produced is through the interaction of accelerated electrons with the remaining laser target, these bursts are extremely short – in the region of a few ps. As a result, the laser-produced x-rays are capable of imaging complex dynamic objects...

The selection and use of any method to be used for radiography depends on a number of considerations, these in general being: a) The size, shape, orientation and distribution of imperfection in the weld. b) The dimensions, geometry and physical properties of the weld and material. c) The radiographic sensitivity required by the Standard, Code or Specification. d) Cost of radiography. e) The loc...

OBJECTIVE To assess whether accident and emergency (A&E) nurses using the Ottawa Ankle Rules could detect all ankle fractures. DESIGN Prospective observational study. SETTING A&E department of a university teaching hospital. SUBJECTS All patients who presented with ankle injuries who were initially assessed by a nurse taught the Ottawa Ankle Rules. OUTCOME MEASURES (1) The numbers of pa...

Pressure induced densification and compression of a reprocessed sample of borosilicate glass has been studied by X-ray radiography and energy dispersive X-ray diffraction using a Paris-Edinburgh (PE) press at a synchrotron X-ray source. The reprocessing of a commercial borosilicate glass was carried out by cyclical melting and cooling. Gold foil pressure markers were used to obtain the sample p...

The availability of computed radiography has opened the possibility of using reduced dosage for radiographs in clinical settings and reducing the retake rate. A prospective controlled study was carried out over a period of four months comparing conventional X-rays and computed radiography. The aim was to assess if computed radiography at 50% normal dosage would result in films of adequate quali...
