Paper Abstract

BRAGA (Bedside Radiography Automatic Grid Alignment) is a means of easily and automatically aligning the x-ray tube and grid in bedside radiography. BRAGA permits the use of high ratio (12:1 or 15:1) grids and produces portable radiographs with markedly improved image quality compared to conventional techniques, with no increase in patient dose. BRAGA's design and operational principles are described. Virtually perfect focal spot grid alignment is achieved in less than ten seconds with little additional effort on the part of the technologist. Presented are comparison conventional (non grid) and BRAGA (15:1 grid) chest portable radiographs obtained employing the same kVp, mAs and patient dose. The BRAGA X-ray has markedly better image quality than the conventional portable X-ray.
