Tissus mous (fantôme)
Phantoms of soft tissues are easier to handle and eliminate the problem of sample-specific differences.
À propos de ce matériau
(En anglais seulement) Phantoms of soft tissues are easier to handle and eliminate the problem of sample-specific differences. They are widely used in surgical training from imaging technique (MRI, X-Ray, uCT, etc.) to the modelling of interactions between devices and soft tissue. Mechanical assessment of phantom materials is essential since they need to closely mimic the properties of soft tissues with the goal of transposing the findings to medical procedures.

FAQ
Qu'est-ce que le module d'Young E?
Propriété mécanique intrinsèque d'un matériau indépendant de sa géométrie. Correspond à la pente du stress par rapport à la contrainte pendant une compression non-confiné lorsqu'on tiens compte de la géométrie de l'échantillon.

Comment fonctionne le modèle "Sinusoid"?
(En anglais seulement) This feature is used to obtain the Frequency, Amplitude and Offset of a sinusoidal signal. A blue line displays the theoretical sinusoid with the Frequency, Amplitude and Offset obtained (Figure 1). The values of the Frequency, Amplitude and Offset are indicated in the "Results" field. The units vary according to the graph’s axes.
This feature can also be used for sinusoidal stimulus-response analysis. Sinusoidal stimulus shall be selected on the x-axis and the sinusoidal response on the y-axis. The Modulus is the ratio of the response Amplitude over the stimulus Amplitude. The Phase is the phase difference between the response and the stimulus. The Modulus’ is computed as the Modulus*Cos(Phase) and the Modulus” is computed as the Modulus*Sin(Phase). A blue line displays the theoretical sinusoidal stimulus-response with the Frequency, Modulus and Phase obtained (Figure 2). The values of the Modulus and Phase are indicated in the “Results” field. The units vary according to the graph’s axes.
One use for this feature would be to compute material properties by multiplying the Modulus obtained by the appropriate geometric factors. For example, the Young’s Modulus can be obtained during uniaxial compression or tension on cylindrical sample with t/pi*r2 as the geometric factor, t is the thickness and r is the radius of the sample.
