In figure 1.40 (see attachment), calculate the X-ray intensity, as a function of the incident intensity I_o, that reaches the film for each of the three X-ray beams. The dark-shaded area represents bone and the light-shaded area represents tissue. The linear attenuation coefficients at the effective X-ray energy of 68 KeV are 10 and 1 cm^-1 for bone and tissue, respectively.© BrainMass Inc. brainmass.com October 25, 2018, 7:59 am ad1c9bdddf
This is a problem on solving the X-ray intensity using the incident intensity.
X-Ray Spectrum and mammography
A)Describe the two physical processes that give rise to the production of X radaition when electrons bombard the target of a diagnostic x-ray tube operation at 1000kvp. Explain the shape of the energy spectrum of photons from the target, detailing how this is modified by changes in kVp and target material.
(b)Describe how this spectrum may be modified using filter and account for changes to the beam intensity and penetrative qualities when filters are used. Explain why compound filters are sometimes used to filter x-ray beams.
(c)Describe briefly the different spectrum of X-rays used for mammography examinations.View Full Posting Details
