WitrynaAn improved version of SIRT algorithm for improving image reconstruction from projections in computerized tomography that analyzes the projection in the iterative routine as an algebra routine and gives much better results than the classical one. WitrynaComputer-assisted coding tools have the potential to drive improvements in seven areas: Transparency of coding. Productivity (generally by 20 to 25 percent for inpatient claims). Accuracy (by improving specificity of documentation). Cost containment (by reducing overtime expenses, audit fees, and denials). Compliance. Efficiency. Consistency.
