What is the model of economic benefit evaluation and demonstration of medical imaging information system?

In the economic benefit evaluation and demonstration of vector imaging information system, various models can be used for analysis and evaluation. Commonly used models include cost-benefit analysis, cost-utility analysis and decision tree analysis. Among them, cost-benefit analysis and cost-utility analysis are common models. By comparing the relationship between cost-benefit or utility before and after the system is used, we can further judge the economic benefits of the system implementation. Decision tree analysis compares several branch schemes by making a decision tree model, so as to obtain the economic benefits produced by implementing different schemes. The application of these models can improve the scientificity and accuracy of economic benefit evaluation.
