Description
Temporal bones of the head phantom are small phantoms with a three-layered bone structure similar like an actual skull bone (cortical bone on top and bottom and diploe in the middle.).
Upon request, we can adjust the porosity and thickness of the diploe layer and by doing so we can adjust the ultrasonic attenuation of the phantom.. True Phantom Solutions are pioneers in developing these phantoms and hold strength in customizing them.
The design of this phantom is based on an average temporal bone of a male skull and it is made out of realistic patented bone material that is suitable for Ultrasound, MRI and CT applications (any other part of the skull can be fabricated based on the customer order).
The phantom has a realistic three-layered structure and the inner porosity can be adjusted according to the requirement of the particular project.
