Description:

Outer dimensions:

270 mm * 255 mm * 210 mm

Weight: ~8.5 kg.

The box is cast in polyurethane and covered with a lid of PVC.

The back ground mass in the phantom has an attenuation of ~ 0.5 dB/cm*MHz. Speed of sound is 1540 m/sec. The backscattering is very high

It contains 5 cone shaped objects with low backscattering down to – 40 dB. Each  object has a cone shaped echo free centre.

Instructions:

Angle the transducer to intersect the objects at 90°. Notice at which distance or size the backscattering from the different objects can be distinguished from the noise in the echo free centre. This distance / size can be used as an indicator for the high contrast resolution.

Caution:

The phantom will not stand frost.

The surface must be covered with preservative fluid.

Be careful not to trap air bubbles inside the phantom

Handle with care.
