Gain confidence in the accuracy of your treatment plans and help improve patient outcomes
Verify Patient IMRT Treatment Plans
The anthropomorphic design of the IMRT Dose Verification Phantom mimics human anatomy which assists in set up and treatment for patient dose verification. It is ideal for prostate and head and neck regions, as well as for commissioning respiratory gated protocols because the accuracy of prescribed dose is evaluated and confirmed in simulated patient conditions. The IMRT Dose Verification Phantom is available in Acrylic (Item 682-700) or Virtual Water™ (Item 682-702).
Fast & Versatile Set-Up Helps Complete Dose Verification Quickly & Easily
The IMRT Dose Verification Phantom can combine absolute, relative and point dose measurements, with up to 16 chamb er positions, 5 film positions and up to 9 diodes or TLDs. By using a fast coronal film orientation, the IMRT Dose Verification Phantom captures the dose contribution of all fields and segments, as well as showing hot and cold spots on the film, for comparison to the treatment plan. The IMRT Dose Verification Phantom effectively evaluates head and neck junction issues of upper neck and half beam superclav fields. It also incorporates inhomogeneity structures with bone and lung equivalents.
 Assure Accuracy in Respiratory Gating With the Optional Respiratory Gating Platform
The unique Respiratory Gating Platform (Item 682-713) simulates breathing providing the means to create a comprehensive program for commissioning, training, quality assurance, and dose verification of gated IMRT treatments.
Features and Benefits
•  The Ion Chamber Slab has six cavities for thimble ion chamber measurement. The diameter of each cavity is 19 mm. Solid acrylic (Virtual Water) plugs are included to fill the cavities for simulated patient thickness. One solid plug is drilled for the ion chamber of choice. A bone equivalent plug is included for bone simulation of heterogeneity measurements.
• The Blank Slab is a solid slab to provide simulated patient build-up material. Four 2 mm steel balls are imbedded in the slab as reference markers for 3D orientation of film on TPS.
• The Lung Slab has two cavities for simulated lung inserts, two cylindrical cavities for thimble ion chamber placement and a set of two tissue equivalent lung inserts for lung simulation. Optional Acrylic inserts convert the Lung Slab into a solid slab
Optional Accessories
• The Acrylic and Virtual Water™ MOSFET Diode/TLD Slabs (Items 682-705 and 682-706, respectively) have nine channels for MOSFET diodes or TLD chips which can be placed at any point in a field for point dose measurements. The small channel size was designed not to perturb other measurements allowing these slabs to be used as solid slabs for increased patient thickness. MOSFET diodes are isotropic for dose measurements from any angle.
• Optional Inserts (Item 682-708 for Acrylic, or 682-709 for Virtual Water™) convert the Lung Phantom Slab into a solid slab.
• Carrying Case (Item 682-715) has extendable handles and wheels for easy transport.
• Simulate tumor movement with the Lung Tumor Insert (Item 682-712)
