[Method of processing the results of dynamic radionuclide studies based on methods for solving incorrect problems]

The authors have proposed a method for the calculation of distribution function of the time of a radioactive indicator entry in the studied organ. Function type is determined by a technique of indicator injection in the vascular bed and the state of the major vascular pathways of indicator transfer from an injection spot to a recording spot. The calculation technique is based upon the application of the methods of the solution of ill-posed problems to the calculation of the parameters of a model of indicator primary passage through the organ. Typical calculation results for the left ventricle have been presented. Areas of the application of the method to radiodiagnostic investigations have been outlined.
