X-ray film has been traditionally the mainstay both of diagnostic radiology and XRD. Efforts to replace it with digital detectors, such as the photo-stimulated luminescence plate [8], have benefited both fields. There has been enormous investment in silicon-based X-ray detectors enabled by the semiconductor industry, and these are found in increasing measure in conventional X-ray diffractometers.

As far as applications of XDI, the comparison with MRI is illuminating. MRI has from its beginnings found a ready application for soft-tissue imaging in diagnostic radiology, driven by the powerful market forces at work in the health-care sector. 

X-ray diffraction imaging in its early days followed a similar path to target medical diagnostic applications. Several investigators found remarkable differences between the diffraction profiles of healthy and diseased tissue in the skeleton [11] and breast [12], to name just two examples. Dose considerations however, particularly compared with MRI, have prevented up to now the widespread application of XDI in diagnostic radiology.

Many quality assurance procedures in diagnostic radiology require the use of a phantom to simulate the X-ray attenuation of the patient. The phantom should transmit the same quantity and quality (i.e. spectrum) of radiation as that transmitted by the patient. The knowledge of photon spectra at the position of measurement on the surface, inside and behind standard dosimetric and imaging phantoms is helpful for performing dosimetric or calibration measurements and hence helpful in the course of quality control. The experimental approach is limited however, simulation with Monte Carlo methods has been proved to be a very powerful technique (Petoussi et al., 1992). 

An ideal contrast agent should have the following properties fa) ready availability and low cost fb) excellent x-n> absorption characteristics at the x-ray eneigies used in diagnostic radiology (c) minimal toxicity and ready patient acceptance (d) chemical stability fe) high water solubility ilh low viscosity and no significant osmotic effects and ifi the ability to be administered for selective tissue uptake cod excretion.
