The use of texture analysis in magnetic resonance imaging requires the availability of texture test objects for use in standardisation of in vivo measurement. A series of such objects of varying texture has been developed using reticulated foam, whic

Texture analysis in magnetic resonance imaging has the ability to provide useful diagnostic information with respect to the discrimination of disease states of a single tissue or the separation of different tissues. However, for widespread use it is

Successful methods of ultrasonic characterisation of alcohol-induced diffuse liver disease using texture analysis (Lerski et al. 1979, 1980a, b) have studied the radiofrequency (RF) A-scan ultrasonic signal. In the present paper the Fourier spectra o

A standard method has been developed for the production of reference materials for NMR relaxation time measurement. These are based on agarose gels doped with gadolinium. The reproducibility and temporal stability of the gels have been found to be ex
