Abstract
A calibration for standardizing images taken with X-ray radiation includes an elongated parallelepiped box of dimensions of at least about 14' (35.56 cm) by 17' (43.18 cm), which are the standard dimensions of normal size X-ray film and, computed radiography plates made predominantly of methyl methacrylate and including three sections arranged along the direction of elongation of the box including a thick body section having a first thickness, the sections having imbedded specimens simulating X-ray absorption characteristics of human body portions, including a needle with an eye, step wedge, nylon disks, and copper screens of varying mesh sizes; a thin body section having a thickness less than the first thickness and imbedded pairs of models; and a thoracic body section having a thickness less than the first thickness and including a natural sponge simulating the X-ray absorption characteristics of a human lung and a plurality of air pockets of varying depth in the transmission direction to simulate pneumothoraces on an X-ray film or computed radiography image.
