Use of Signal to Noise Ratio for Daily Quality Control of Fluoroscopes Used for Interventional Radiology Procedures
Research on automated fluoroscopy QC using QC-Track in an IR lab was presented by Allen Goode, M.S.,
Chief Diagnostic Medical Physicist, University of Virginia Health System, as an
ePoster
at the 2018 AAPM Annual Meeting.
The
research effort
was led by Allen Goode, M.S., and included his team at the University of Virginia Health System in collaboration with the
research team at Atirix Medical Systems.

ACR acknowledges Atirix recommendation of SNR as alternative to spoke counting for MRI QC
The American College of Radiology (ACR) MRI accreditation program has officially acknowledged signal-to-noise ratio (SNR) as an alternative measurement to low contrast detectability
for weekly MRI quality control.
This addition came at the suggestion of Angela Snyder, Ph.D, Director of Research for Atirix Medical Systems,
who advocated for the alternative quality measure.
Using SNR as the daily/weekly measurement of MRI image quality:
-
offers greater sensitivity to subtle performance changes,
-
has a broader range than spoke counting,
-
is quantitative rather than qualitative, and
-
for facilities using QC-Track’s automated phantom analysis module, is a faster measure to obtain than spoke count, leading to more efficient MRI QC.
The ACR’s statement on using SNR in place of low contrast detectability can be found at the bottom of the
FAQ
section of the ACR’s MRI accreditation web page.
Effective September 2016 - Current
Steve Backes, President and CEO of Atirix, is a consulting member of AAPM Task Group No. 272 - Comprehensive Acceptance Testing and Evaluation of Fluoroscopy
Imaging Systems.
Atirix is using QC-Track to support the research efforts of the
TG272 Quality Control subcommittee.
