Doppler Phantom

Description

Doppler Phantoms are used for medical imaging research & development, training, and testing purpose(s).

These can be customized in multiple ways to suit the needs of our client’s applications. The following are the features that comes along with the DP-C01 model:

• Partial skull phantom with a customized thickness;
• Filling the phantom with the acoustically correct brain mimicking material
• Custom blood vessels
• Standard tubes and connectors connected to the custom vessels
• Incorporating the phantom within a standard compact box
• Implementing a thin film on top of the phantom
• Custom target wires
