REDUCING AN X-RAY DOSE APPLIED ON A SUBJECT DURING A RESPIRATION-CORRELATED COMPUTED TOMOGRAPHY SCAN

REDUCING AN X-RAY DOSE APPLIED ON A SUBJECT DURING A RESPIRATION-CORRELATED COMPUTED TOMOGRAPHY SCAN

A computer-implemented method for reducing an X-ray dose (12) applied on a subject (5) during a respiration-correlated computed tomography scan, the method comprising the following steps:(a) during a beam-on period of the scan, determining the beginning of a data-redundant breathing phase;(b) during...

Zusammenfassung:A computer-implemented method for reducing an X-ray dose (12) applied on a subject (5) during a respiration-correlated computed tomography scan, the method comprising the following steps:(a) during a beam-on period of the scan, determining the beginning of a data-redundant breathing phase;(b) during the data-redundant breathing phase, applying a redundancy modulation to the applied X-ray dose such that the X-ray dose is reduced during the data-redundant breathing phase;(c) determining the end of the data-redundant breathing phase;(d) at the end of the data-redundant breathing phase, continuing the scan without the redundancy modulation of the X-ray dose.
