Prognostic significance of 3D non-linear picture reconstruction in practical diagnostics is still being updated at the present moment. One of the possible upcoming trends of usage of the given procedure is an early detection of pathological changes in gastrointestinal tract organs which requires emergency and scheduled surgical measures.

    NLS-diagnostics may become a procedure of choice for detection of concrements and dilatation degree of bile passages. When examining of patients with choledocholithiasis the classical picture of concrement is a hyperchromogenic structure of various forms. The accuracy of 3D NLS-diagnostics of choledocholithiasis is more than 95.0%.

    The minimal size of detected concrement in gall bladder is about 5 mm for NLS-diagnostic systems. Acquired image of concrement and gall bladder walls accuracy significantly improves when using 3D picture reconstruction mode in 3d nls health analyzer.
