a) Draw a diagram of an x-ray image intensifier used for medical fluoroscopic imaging. Label the 6. main components and explain their functions (10] b) Explain what is meant by the brightness gain of an image intensifier. Name and describe the two processes that contribute to this gain. Give expressions or numerical estimates where appropriate 15) c) Suppose that an x-ray beam is incident on an image intensifier having a diameter of 30 cm. For this x-ray beam, the incident...
Fluoroseopy Fluoroscopy is a studdy of moving body strctures. It is an imaging technique that uses X-rays pass the body part to he esamined to obtain real time moving images of the internal structures of a patie the use of a fluoroscope. In its simplest form, a fluoroscope eonsists of an X-ray source and fluoew between which a patient is placed. It is most commonly used to view the upper Gl tract (stomach, cduodenum, the lower GI tract. Modern huoroscopes...
Please Explain in details thanks Explain why there is (a) a limit less than the kVA rating of the alternator on the kVA the machine can supply at unity p.f., and (b) why there is a limit on the kVA the machine can supply at 0.8 p.f. lagging.

Please kindly explain why the answer is B, it a reaction is
less than Zero?
TIF AGⓇ for a reaction is less than zero, what can you say about the value of K for the reaction? a. K<land the reaction is spontaneous under standard conditions. K >1 and the reaction is spontaneous under standard conditions. = r standard conditions. => Why if da Reaction R = 0 and the reaction is at equilibrium. is less that ou (d) <0 and...
