Electrocardiogram pulsing, adaptive pitch cut coronary CTA dose
By Eric Barnes
Educational Exhibit | LL-PH4828-L09 | Lakeside CenterTwo important dose reduction techniques are illustrated in this exhibit: adaptive electrocardiogram-pulsing and adaptive pitch selection. The rationale and physics behind these techniques are discussed and, more important, illustrated with the aid of real-world examples and cases, according to CT physicist Marcel van Straten, Ph.D., from Friedrich-Alexander University Erlangen-Nuremberg in Germany.
