QA Software • IMRT QA and IN-VIVO DOSIMETRY The world’s first commercially available patient transit dose system. Dosimetry Check software works with any Amorphous- Use the dose volume histogram (DVH) display to compare Silicon Imaging System to provide Pre -Treatment and In- planned, pre-treatment delivery and measured patient Vivo Transit Dose QA. Treatment techniques include VMAT, transit delivery at the same time. Comparisons show RapidArc, Conventional IMRT and Stereotactic deliveries. differences between the planned and delivered doses so Calculate 2D, 3D and multiple point doses and compare between planned, pre-treatment delivery and measured transit delivery. Use Gamma function to compare measured transit delivery to either planned or pre-treatment delivery. clinicians can make decisions about adaptive changes that might need to be made during treatments. QA Software Features • EPID Dosimetry Pre-Treatment QA with nothing to set up and no phantom required, Just shift the couch out of the way, extend the EPID and expose treatment plan. • 3D predicted (planned) vs. absolute dose (measured) analysis with integrated dose verification using patient CT data set • EPID Dosimetry Transit QA provides confirmation of dose delivered and measures absolute in-vivo dose in cGy viewable in 3D on patient contour. • Full 3D comparison of dose within the patient, including effects of inhomogeneities. Any dose, anywhere within CT Volume. • Requires no additional linac time for physicist. Therapists run plans and acquire portal images when convenient, Medical Physicist does analysis off line during business hours. • Structure analysis provided in 3D dose volume histograms (DVHs) and gamma volume histograms (GVHs) • Exceptional 0.25mm spatial resolution compared to 2D/3D arrays. No extra detector or array to purchase and maintain. • Supports conventional IMRT, VMAT, RapidArc, Stereotactic, and Transit • • • Works with any treatment planning system. Independently measured dose calculations with or without the patient in the beam. All correction algorithms built in. • Provides 2D and 3D anatomical dose results analysis of pre-treatment and on-treatment in-vivo measurements of patients. • Dosimetry Check utilizes patented methods with algorithms validated in multiple publications. • Purchase includes all computer hardware and software, plus on site set-up, commissioning and training. • Actual patient plan and dose distribution is verified – not recalculated dose to a (frequently homogeneous) phantom. Works with Elekta iView portal imager; Varian’s portal vision; R and E arm portal imagers and Siemens Optiview portal imager D o s i m e t r y c h e c k s o f t wa r e S p e c i f i c at i o n s REF Number RDC-001, RDC-002, RDC-003, Memory 8 GB or greater RDC-004, RDC-005 Hard Drive 500 GB or greater Computer Included with purchase Screen Resolution Processor CD-ROM Drive 8X speed or greater Intel® i7 or greater 1024 x 768 or higher Specifications subject to change without notice. p e r f o r m a n c e va l i dat i o n WD Renner, et. al., “A dose delivery verification method for conventional and intensity-modulated radiation therapy using measured field fluence distributions”, Medical Physics, Vol. 30 No. 11, Nov. 2003, pages 2996-3005. www.AAPM.org WD Renner, K Norton, T.
