- Page 3 The phantom can be filled with various MR signal-generating solutions. When empty, the grid/air interface provides good contrast in CT imaging.(When the CT images of the phantom are to be analyzed by CIRS MRI Distortion Check Software, it is highly recommended that the phantom is filled with liquid for scanning.) The phantom is marked with cross-hairs for ease of alignment to positioning lasers and can be used on curved and flat gantry tables.
- Page 4 After filling with water, position the phantom on dry paper and let sit for approxi- mately 1 hour. Inspect for wet spots. If a leak is evident, notify CIRS or your distributor. FILLING THE PHANTOM For safety, familiarize yourself with filling and draining operation prior to filling the phantom with water or test substances.
- Page 5 Place funnel into one of the filling ports at the top of the housing. SLOWLY fill the phantom with water or test substance through the funnel. Note: this should take approximately 15 minutes. • FILLING THE PHANTOM WITH TAP PRESSURE CAN CAUSE EXCESS PRESSURIZATION ON THE HOUSING WHICH CAN LEAD TO CATASTROPHIC FAILURE.
- Page 6 STORAGE CIRS has tested the 3D grid which maintains geometric stability when the tank is filled. The PMMA housing is hygroscopic which can jeopardize the integrity of the phantom if left filled over a long period of time. Through water absorption on the inside of the housing, the PMMA exhibits a differ- ential distortion through the inside expanding and outside remaining at atmospheric conditions.
