TomoTherapy to Introduce TQA™ at 50th Annual AAPM Meeting : Industry’s First Integrated Machine QA Solution Expands Data Access, Improves Clinical Workflow for Hi·Art® Treatment System Users


at the 50th Annual American

Association of Physicists in Medicine (AAPM) Meeting in Houston,

July 27-31, 2008. TQA, or Tomo Quality Assurance,

is the first integrated, machine-specific quality assurance (QA)

solution to be offered by a radiation therapy vendor. The TQA application

streamlines the collectionand simplifies the

reviewof data used to monitor radiation

therapy equipment and procedures. All TQA data can be easily

exported for third-party validation.

TQA was built by, and for, our physics colleagues in the clinic

TQA has been developed by TomoTherapy in partnership with medical

physicists experienced in the clinical use of the Hi·Art®

treatment system. Bob Cravens, M.S., TomoTherapys

lead applied physicist and TQA architect, believes customer input

was critical in bringing this powerful set of physics tools to market.

News ImageTQA was built by, and for, our

physics colleagues in the clinic, says

Cravens. They helped us identify key data

and workflow requirements1, and provided

valuable feedback throughout the development process. The result is an

application that integrates easily into daily workflow, increases

productivity and facilitates more informed decision-making.

Additionally, it better aligns our support team with TomoTherapy

customers, allowing them to share the same data set.

The TQA application leverages the Hi·Art

treatment systems unique platform

integration. It works by gathering data from the on-board detector and

other sub-systems that monitor the device continuously during delivery.

The data is then presented in a customizable, calendar-based interface

that is accessible from the Hi·Art

systems operator station. With this

comprehensive data dashboard, any parameters

status can be identified at a glance and comparatively assessed via

automated reporting and trending features.

TQA can provide a wealth of

additional information, which means I can work more proactively and

better assess the system with predictive analysis,

said Walter Grant, Ph.D., chief of Physics at Baylor College of Medicine

and The Methodist Hospital in Houston, one of 16 customers to evaluate

the application. TQA can also

save me considerable time. In evaluating the application, I have found

QA measurements that took over an hour to complete, analyze and document

can now be finished in 10 minutes. This will certainly make my life


Cravens stated that TQA will provide immediate benefits to customers who

are new to the Hi·Art platform as

well: We often hear that Hi·Art

is the easiest system to use, once our customers have become familiar

with it. TQA should help clinics hit the ground running even

faster. Its a turnkey operation, complete

with QA guidelines, that eliminates unnecessary complexity.

Noted TomoTherapy CEO Fred Robertson: We are

excited to introduce TQA at AAPMs 50th

Annual Meeting. Integrated machine QA is one more example of whats

possible with our truly integrated platform for radiation therapy, and

one more reminder that we are really just at the beginning of our

product lifecycle. There are many more productivity- and quality-focused

enhancements to come.

Bob Cravens, M.S., and Walter Grant, Ph.D., will each be discussing TQA

in the TomoTherapy booth during AAPM. For exact times of these and more

presentations throughout the week, please visit AAPM booth #519, or the AAPM
