The Tumor is a perfect example of a feature which can be implemented to any location of the brain or simply submerged in a brain mimicking material used to fill the skull or head phantom. The features shown on the images are made out of homogenous tissue mimicking material with realistic acoustical and MRI properties.
Type of Tissue | Sound Velocity [m/s] | Density [g/cm³] | Hardness [Shore 00] | T2 [ms] | Speckles | Attenuation Measured at 2.25 MHz [dB/cm] |
Tumor | 1400 ± 10 | 1.01 | 30 | 65 | YES | 1.2 ± 0.2 |
Soft tissue and organs: Composition of urethane base soft resin
