| 1. | Where " b " ext is the attenuation coefficient.
|
| 2. | A small attenuation coefficient indicates that the material in question is relatively opacity.
|
| 3. | Attenuation coefficients vary widely for different media.
|
| 4. | For each of these ranges, there are attenuation coefficients defined according to link geometry.
|
| 5. | The molar attenuation coefficient is usually decadic.
|
| 6. | The attenuation coefficients of common biological materials at a frequency of 1 MHz are listed below:
|
| 7. | The attenuation coefficient is dependent upon the type of material and the energy of the radiation.
|
| 8. | Where \ mu ( x, y ) is the attenuation coefficient as a function of position.
|
| 9. | Measurement of attenuation coefficient versus ultrasound frequency yields raw data for further calculation of various system properties.
|
| 10. | The attenuation coefficient is at least as large as the absorption coefficient; they are equal in the idealized case of no scattering.
