Smarthelical; Advanced Artifact Reduction (Aar); Adaptive Statistical Iterative Recon (Asir-V); Kv Assist - GE Revolution CT User Manual

8.3.5 SmartHelical

SmartHelical is integrated into all GE CT systems. It decreases image noise as measured by
pixel standard deviation.

8.3.6 Advanced Artifact Reduction (AAR)

A filter that significantly reduces streaking artifacts when highly absorbent objects are in the field
of view (example: large shoulders). AAR is automatically enabled as needed.

8.3.7 Adaptive Statistical Iterative Recon (ASiR-V)

The next generation ASiR-V is a reconstruction technology that may allow for reduced mA in the
acquisition of diagnostic images thus, enabling the physician to reduce the patient dose
depending on the clinical task, patient size, anatomical location, and clinical practice.

8.3.8 kV Assist

kV Assist provides the capability to adjust the kV and NI/mA based on the clinical task of the
protocol and patient size to optimize patient dose.

8.3.9 Auto Gating Configuration

Auto Gating uses the scout to evaluate patient attenuation to calculate patient size and a kV/mA
table for selectiing kV, mA, SFOV, and ASiR-V level for the protocol.

8.3.10 Dose Reports

CTDI , DLP and Dose Efficiency are displayed during the scan prescription and provide patient
vol
dose information. The CTD
saved once you end the exam. The Dose Report is saved as a DICOM secondary capture
image in Series 999. This series can be filmed, archived, and networked after the scan is
completed.
DICOM Structured Dose Report generates a CT Dose Report, which can enable tracking of
dose for the patient by the hospital radiation tracking system or HIS/RIS. The Dose Report is
saved as a DICOM SR Object in Series 997.

CTDI , DLP, and Dose Efficiency are displayed during the scan prescription to provide patient
vol
dose information.

8.4.1 Prerequisites

Before DICOM Structured Dose Report is turned on, confirm that your PACS or other receiving
station supports structured reports.
Contact your service representative to enable DICOM SR Dose Report.
