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.
