STANDARD IMAGING: Solutions
Based Quality Assurance
What is Solutions based QA
Using various accepted protocols as a template 1) AAPM TG-51, TRS398, etc. (Absolute Dosimetry) 2) AAPM TG-142, etc. (Linac and Systems QA)
Performing routine scheduled QA for monitoring Linac performance and maintaining improved patient care with QA Tools offered from Standard Imaging.
Solutions Based QA covers most routine Quality Assurance for Linear Accelerators and associated systems (EPID, CBCT, OBI, Treatment Couch, etc.)
as well as Patient Specific QA
Standard Imaging, Inc. provides the full compliment of QA Tools and Software to allow you to perform almost all of your LINAC QA

Lung Patient Sample
Patient misaligned on fraction 18
Today’s tumor location
Planned tumor location
Adaptive module showed:
Planned dose:
Fraction 18 dose:
Lung Patient Sample
Fraction 18 daily DVH
Cumulative DVH up to and including Fraction 18 treatment
Physician now has the information to determine whether this single day’s misalignment will compromise the patient’s overall treatment!
H&N Patient Sample • Patient lost weight throughout
treatment
• Mask was poorly made: inconsistent daily setup
• Effect of these changes are tracked in Adaptivo
Decreasing target volume
Significant differences between planned and delivered dose
DVH differences between planned and delivered cumulative doses
Streamlines and automates pre-treatment QA Provides daily treatment delivery monitoring Determines both daily and cumulative delivered dose by
using the most recent CBCT not only the plan CT. Automates calculation and notification Provides a complete integrated solution for Patient
Dosimetry
ADAPTIVO In Summary:
Additional Tools
LinacView™ Log file Analysis Software • Logfile analysis for every patient.
Analyze machine performance for each fraction automatically with no impact on patient workflow.
QA Pilot Delivers on Data Integrity
• QA Pilot uses Amazon Web Service (AWS) Infrastructure. • Physical Security
– Physically dispersed, hardened data centers. – Data backed up in a minimum of 3 places.
• Network Security – Best in class network architecture and practices. – Data encrypted while at rest and in transmission.
• Operational Security – Full HIPAA/HITECH compliance – Best in class personnel access management.
• Ask yourself if your organization’s IT department has the same resources and depth of experience and track record as Amazon.
• They may be very good but are they absolutely world–class?
