Flood Phantom

Flood Phantoms offer a simple, efficient means of obtaining optimum camera performance with respect to uniformity of response over the entire crystal area. They consist of plastic forms that contain a watertight central cavity into which a radioactive solution is introduced (via a filling port) and then mixed thoroughly. After the activity has been distributed evenly, the camera’s uniformity of response can be checked.

Applications:

When evaluating SPECT (ECAT) equipment, flood uniformity is essential to prevent the formation of artifacts in the image. For this purpose, we have developed special flood phantoms which, unlike conventional versions, are filled in the horizontal (fl at) position. This prevents the slight bulging caused by water pressure during vertical filling. By reducing variations in cavity thickness, better uniformity in distribution of activity can be achieved. An air bubble trap is built in.

Two flood phantoms are available: Rectangular, and Extra Large Rectangular. Filler and vent ports are located on the face. Shipped empty; radioactivity is not included.

Features

• For checking uniformity of response
• Horizontal filling prevents “bulging”
• Four flood phantoms are available: Regular and extra-Large Rectangular
