• Comprehensive TG-142
ImaGInG and machIne QaAutomate the analysis of over
30 TG-142 recommended QA tasks without film
TG-142 imager and machine QaThe continual refinement of RT treatments into more advanced
procedures dictates the need for superior, sustainable precision. However,
imagers and machines degrade over time and recalibrations are required.
TG-142 reconciles these divergent trends by recommending a multitude
of daily, monthly and annual QA procedures. Though aimed at preventing
clinically significant errors, these requirements further strain the busy
schedules of RT professionals.
PIPSpro Software efficiently executes and consolidates QA workload by
incorporating TG-142 procedures into one easy-to-use platform. When
used in conjunction with specialized phantoms, PIPSpro becomes an
indispensable part of your QA process.
•Assurance is ConfidenceSeveral manufacturers still include basic, qualitative phantoms, like the ‘Las Vegas’
test object, with their imaging systems. However, these phantoms do not provide
quantitative data. In addition, these tests are done manually, without the aid of
software to automate results.
In contrast, Standard Imaging
phantoms provide quantitative,
repeatable results. This data can be
compared to published performance
values or between systems to
ensure your imagers are operating
to specifications. These powerful
trending tools alert you of issues
before loss of quality becomes
clinically significant.
Refined User -Inter faceThe QA modules of PIPSpro feature a new, simplified
user-interface. since the interface is consistent across
modules, it is easy to quickly learn all facets of pipspro.
Additionally, this unified layout allows multiple modules
to be open simultaneously - streamlining workflow
during acquisition, reporting and analysis routines.
pipspro Comprehensive’s imager Qa, star shot and stereotactic, when coupled with the appropriate phantoms, facilitate over 30 tests recommended by TG-142. (Phantoms appear in parentheses)

Enhanced Imager QA moduleThe Imager QA module consolidates TG-142 testing for MV, kV
and 3D CT (both cone-beam and diagnostic) into a uniform, easy-
to-use interface. Customizable profiles allow a variety of machine,
imager, phantom and energy combinations to be quickly saved.
Once a profile is selected, the user loads an image for analysis and
PIPSpro does the rest. This “one-click” deployment provides three
different figures of merit for calculating uniformity, including
PIU (ACR percent integral uniformity).
A comprehensive baseline manager lets users customize imager
QA. This tool can generate and store custom baselines for
every test calculated within PIPSpro, allowing for a breadth of
metrics to be easily tracked. Once testing is complete, PIPSpro
automatically generates comprehensive reports that can be
quickly exported to a PDF file. These reports contain a summary
page detailing which values pass or are out of range, along with
images of each result. All data is automatically tagged as green,
yellow or red for an easy overview of passing/failing results.
additional New Features• Unified interface allows for multiple modules of PIPSpro to be
open simultaneously.
• Supports the Catphan 600 and Leeds phantoms, as well as the
independently calibrated QC-3 and QCkV-1 phantoms.
• Phantom imaging does not require jaw or blade positioning.

Quantify the quality of your imagers
Track and Trend Imager PerformancePublished image resolution data for PIPSpro’s QC-3 phantom
provide a known quantity for each imager, making it easy to
evaluate the quality of baseline values and compare values
between systems. Using these baselines, the built-in database
and trending software shows how your imagers are performing
over time. User-determined warning and rejection levels on all
graphs let you easily detect declining image quality.
validated Performance, documented ResultsWith performance supported by over 55 publications, PIPSpro
Software, the QC-3 phantom (MV) and the QCkV-1 (kV) phantom
are integral to meeting TG-142 standards. 11 regions of interest
contain line pair patterns and materials of differing densities,
allowing for the planar determination of resolution, contrast
and noise. Compare these results to published data for further
confidence in your QA.
QC-3 Phantom
QCkV-1 Phantom
Simple IGRT Trending
intuitive IGRTWhen using on-board imaging systems for patient positioning,
it is imperative to verify that the imaging coordinate system is
aligned with the treatment beam. TG-142 recommends testing
this on a daily basis. This test is performed using the Standard
Imaging MIMI (Multi-Image Modality Isocentricity) Phantom,
providing results in either three dimensions (X, Y, Z) or in six
dimensions adding pitch, yaw and roll.
The new IGRT Module in PIPSpro is designed to collect this daily
data and then automatically track and trend these values over time.
The MIMI Phantom partners ideally with the IGRT module when
performing daily checks of imaging and treatment coordinate
coincidence. Bone rods running throughout the phantom make
it easy to automatically register and quickly match and analyze
2D/2D and 3D/3D images.
MIMI Phantom
Specialized Phantoms, Superior QA
precise Winston-Lutz/Stereotactic Radiosurgery QAIn linear accelerator based Stereotactic Radiosurgery, it is
common to perform the Winston-Lutz test to verify machine
isocentricity. For the Winston-Lutz test, a spherical marker is
aligned to the laser described isocenter and a series of images are
acquired at different gantry and couch rotation combinations.
PIPSpro Comprehensive simplifies this testing, using your portal
imaging system to acquire the images of the spherical marker
instead of film. These images are automatically loaded and
analyzed to determine the isocentricity. 3D offsets from isocenter
are reported with 0.1mm accuracy allowing you to have more
confidence in your setup and treatment. Testing can be done for
each gantry and couch angle for MLC or cone-based systems.
Winston-Lutz Phantom
Complete MLC QAThe MLC QA module analyzes a single, specialized phantom;
producing quantitative data to determine if your collimator can
accurately position leaves.
This module also follows TG-142 guidelines for reviewing
multiport or ‘picket-fence’ images. These test a MLC’s ability
to position individual leaves at multiple positions during single
treatments such as step-and-shoot and sliding window IMRT.
In addition, the module lets users measure inter-leaf and inter-
bank leakage and leaf-width, making PIPSpro the only software
necessary for comprehensive MLC QA. The MLC QA Module
meets TG-142 guidelines for the following tests:
• Qualitative test [i.e., matched segments, aka ‘picket fence’]
• Setting vs radiation field for two patterns [non-IMRT]
• Leaf position accuracy [IMRT]
• MLC transmission [average of leaf and interleaf transmission,
all energies]
• Leaf position repeatability
• Coincidence of light field and x-ray field [all-energies]
• Segmental IMRT [step and shoot] test
Filmless MLC QA in a single platform
MLC Phantom
advanced Radiation Field/Light FieldThe FC-2 and Center-Marker phantoms expedite analysis of several
TG-142 recommended machine QA procedures, including:
• Light/radiation field coincidence: Meets TG-142 specifications
of measuring tolerances of 2 mm or 1% on a side.
• Jaw position indicators (symmetric): Meets TG-142
specifications of measuring tolerances of 2 mm.
• MLC Coincidence of light field and x-ray field (all energies):
Meets TG-142 specifications of measuring tolerances of ±2 mm.

powerful Star Shot AnalysisPIPSpro’s Star Shot Module uses an EPID or film to measure the
stability of rotation of the linac gantry, couch and collimator.
Analysis of these images provides quantitative results for
mechanical procedures, including:
• Collimator rotation isocenter – Meets TG-142 specification
of measuring tolerances of ±1 mm from baseline.
• Gantry rotation isocenter – Meets TG-142 specification
of measuring tolerances of ±1 mm from baseline.
• Couch rotation isocenter – Meets TG-142 specification
of measuring tolerances of ±1 mm from baseline.
Centralized Database Management PIPSpro can store data on a central network for quick
documentation and access for TG-142 test results and trending
reports. QA results are shown in easy-to-read reports, charts, and
graphs, which can be exported to PDF and ASCII files without
additional software tools. An equipment manager stores an
unlimited number of linear accelerators and phantoms,
eliminating continual re-entering of clinical device data.
Over 55 publications validate the performance of PIPSpro.
The TG-58 Report encourages users to demand the use of a tool such as PIPSpro QC Software at acceptance to help ensure that the EPID is indeed operating at or above specifications.*
