36 Breaking The Rotating AnodeWhen the anode is spinning at the correct speed, the exposure can be made. After the exposure is completed, it slows by reversing the motor. This is necessary to avoid excessive wear and tear of the bearings X-rays have high energy and short wavelength and are able to pass through tissue. On their passage through the body, the denser tissues, such as the bones, will block more of the rays than will the less dense tissues, such as the lung. A special type of photographic film is used to record X-ray pictures 16 The Filaments Tungsten is used in x-ray tube filaments because of it’sHigh melting point of 3410°C.

4 The X-Ray Tube DevelopmentTwo major hazards plagued early radiography. Excessive radiation exposure Electric Shock Moderns tubes are designed to overcome these problems The modern tube is based on the Coolidge tube 35 The Rotating Anode - speedWhen the exposure button is depressed, current is applied to the tube that produces a magnetic field that starts the rotation of the anode. The rotor is the rotating part of an electromagnetic induction motor. It spins at 3000/3400 rpm. High speed anodes spin at 9,000/10,000 rpm. 37 Dissipation of heat from the targetEven with the anode rotating, some melting occurs. The heat must be rapidly dissipated from the target. Molybdenum and copper are used to rapidly transfer the heat from the target. The anode dissipates heat by radiating towards the glass envelop 29 The Stationary Anode Stationary anodes are used in dental x-ray and some portable x-ray machine where high tube current and power are not required. Tube output is low 80kv 15 mA Long exposure times over 100ms Larger focal spots –low resolution Heat is confined to a small area

The X-Ray Engine is a 3D game engine created by Kiev-based computer game developer GSC Game World. Released on 20 March 2007, the engine is used in the first three S.T.A.L.K.E.R. games released by the company: S.T.A.L.K.E.R.: Shadow of Chernobyl. S.T.A.L.K.E.R.: Clear Sky Jump to navigationJump to search. The X-Ray Scope is an item used by Samus Aran in Super Metroid. Samus obtains it in Brinstar at the end of a large dark room. She requires the Grapple Beam to obtain the X-Ray Scope. When used, it allows Samus to see the composition of objects X-ray or radiography uses a very small dose of ionizing radiation to produce pictures of the body's internal structures. X-rays are the oldest and most frequently used form of medical imaging. They are often used to help diagnosed fractured bones, look for injury or infection and to locate foreign objects.. 10 Protective Housing – prevent damageThe housing also provide mechanical support and protection from damage. On some tubes, the housing also contains oil that provides more insulation and a thermal cushion. Never hold the tube during an exposure. Never use the cables or terminals as handles. 19 Filament Current The current that flows through the Filament is called the filament current This is resulted from applying a low voltage across the filament When the x-ray machine is turned on, a low current flows through the the filament to warm it and prepare it for the big thermal jolt necessary for x-ray production.
