Automate Phantom Image Testing
One platform for the daily QA phantoms your CT scanners came with
(GE, Siemens, Canon and Toshiba) and for the ACR accreditation
phantoms in CT, MRI and mammography. ROIs are placed for you and
every number is measured the same way every time. We build your
test routines for you, custom to your specific equipment and
protocols.
Make Accreditation a Breeze
Generate a filled-in PDF from the QC data you already have:
monthly CT and MRI QC laid out for the ACR program, monthly and
annual mammography QC and monthly workstation QC on the CAR forms,
plus acquisition-workstation monitor and artefact reports. The
technologist's answers and initials carry through to the report,
so the evidence and the paperwork never disagree.
Monitor Your Whole Organization
Every scanner, in every room, at every site, on one dashboard you
can filter and sort. A problems list rolls up every failed and
every missed test across all of your facilities, and a status page
tells you whether the gateway is still sending: it checks in once
a minute.
Predict Machine Failure Before It Happens
Not a bare pass or fail. Every measurement is plotted against its
own limits, drawn on the chart as lines you can see. A prediction
interval projects when a value will reach a limit; for CT that
projection is folded into the test result, so if the limit is
fewer than 15 days away AQS calls it a trending problem and tells
you how many days you have. Single results that are outliers
against their own history are highlighted too.
Keep Your Data Safe
HTTPS end to end, images encrypted in transit and at rest, and a
database audit trail of who did what, from which address, and
when. Data can be stored in a location of your choice, including
the U.S., Canada, the EU, and more. Sign-in can be restricted to
your own IP ranges. Retention is continuous: nothing is aged
out, and your tests, your trend data and the original DICOM files
are available on demand in open formats such as Excel and JSON,
for an audit or just to keep your own copy.
Reduce Physicist Site Visits
Let your technologists perform onsite phantom scans. The physicist
reviews from anywhere: the annotated images the analysis produced,
the full DICOM header of any image with a search box, and (with
the DICOM viewer switched on) window/level, zoom, pan and invert
on the original pixels.
Hear About It the Same Day
When a test comes back anything other than a pass, AQS emails the
people you nominate (for the whole organization, for one site, or
for a single scanner) with the items that failed, the trend chart
and a link straight to the test. Scheduled QC that gets missed
raises its own alert once the grace period lapses, and reminders
go out before a test is due.
Your Limits, Your Baselines
Set the limits yourself, right where the number is shown (for one
scanner, for one model, or for every machine on the routine), and
give a value both a fail limit and a tighter problem limit. After
a recalibration or a vendor software update, record
the scanner's new calibration date: the trend starts again from
it, and in mammography the SDNR baseline is rebuilt from the next
five studies. The numbers live in AQS, not in the scanner, so an
update on the console cannot quietly erase them.
Quality-Control Images Only
AQS is built for phantom QC, not patient care. There is no patient
record anywhere in the system and nowhere to put one. The database
holds scanners, rooms, phantoms and measurements. The on-site
gateway can be configured to reject any study that isn't your QC
phantom, before it ever leaves your network.
