EASY, PRECISE, COMPLETE

The 1D Water Scanning System features precise chamber positioning and fast, easy alignment

THE COMPLETE SYSTEM THAT MAKES QA EASY

The 1D Water Scanning System is designed to fulfill the requirements set forth by the AAPM TG 51 and TRS 398 protocols for a one dimensional water scanning phantom. Determining the depth-dose curve and SAD measurements are easily done with this complete system.

WATER TANK

• Available in two sizes: 32 cm x 30 cm x 36 cm and 42 cm x 40 cm x 36 cm
• Vertical lines make it easy to align tank to isocenter using room lasers
• Markers on the tank represent fill lines for 20 cm and 25 cm depth measurements
• Unique drain valve and included draining tube for ease of emptying tank after use

REMOTE HANDHELD CONTROLLER

• Slow, ~ 1.0 mm/sec, and fast, ~ 3.8 mm/sec, travel buttons
• Quick step feature – controller arm moves in exact 0.01 mm increments for precise positioning of the chamber
• Operate the remote hand held controller inside the treatment room connected directly to the water tank or at the control console via a serial extension cable
• Internal memory allows you to set the chamber depth in the treatment room, then disconnect the controller and re-connect to the serial cable at the control console without losing the set depth point

CONTROL ARM

• A rotary encoder is directly mounted to the leadscrew shaft – not the motor shaft – in a superior set up that results in extremely accurate and repeatable measurements
• 0.05 mm accuracy of position and repeatability over the TG 51 range (200.00 mm)

ION CHAMBER BRACKET

• Made of water equivalent material
• Only one chamber bracket required which fits thimble ion chambers and most rigid stem parallel plate chambers
• Alignment lines for aligning chamber’s volume centroid with isocenter
