  Angiography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. An arteriography is  a procedure that produces an image of your arteries . During the procedure, your doctor will use contrast material, or dye, and X-rays to observe the flow of blood through your arteries and note any blockages. This procedure, also known as an angiogram, can be done on many different parts of your body. Venography is a procedure to demonstrate the veins by using contrast media and others materials as for arteriography INDICATIONS   • Blockage of the blood Vessels. • Suspected aneurysm. • Renal artery stenosis. • Renovascular hypertension. • Trauma. • Palpable renal masses. •Chronic pyelonephritis. • Renal abscesses. and determination of the suitability of a (donor) kidney for renal transplantation. CONTRAINDICATIONS   Coagulopathy. Decompensated congestive heart failure

  A Barium Enema is a special type of X-ray examination that allows doctors to examine your lower intestinal tract. After delivering a contrast solution that contains the metallic element barium into your rectum while a technician takes X-ray images of the area. The barium solution will be delivered using an enema — a process in which your doctor pushes a liquid into your rectum through your anus. The barium solution helps to improve the quality of the X-ray images by highlighting certain areas of tissue. The X-ray used in this procedure is known as fluoroscopy. It allows the radiologist to see your internal organs in motion by tracking the flow of the barium solution through your intestinal tract. The test doesn’t require painkillers or sedation, but there may be moments of slight discomfort. INDICATION Abdominal pain  Blood in your stools a change in your bowel movements Crohn’s disease Chronic diarrhea colorectal cancer diverticulitis irritable bowel syndrome polyps rectal bleeding

A Darkroom is a completely light-tigh room where personal exposure will process latend image, load and unload x-ray films. Location   Depending on the department design, it should be centrally sited and serviced by hatch from neighboring conventional or x-ray room Darkroom should be  • Excluded from wet (damp) or hot areas • Have water and power supply • Well Ventilation  Types of darkroom entrance   Typically darkroom requires frequent in and out without admitting white light, special design entrance are needed. 1 Single door 2 Double door 3 Labyrinth door 4 Rotating/Revolving door system  Single door:  - precautions need to be taken to prevent light from entering while processing, when more than 1 person is using the room and in cases of accident (you need to over ride the interlock). Double door: - each door has to be hard in structure and well fitted (to exclude all light when closed). It can be economical and term of space (when the vestibule is small or when door nearest to the

The X-ray Generators delivers the electrical power to energize the x-ray tube and permit the section of x-ray energy, X-ray quality, and exposure time and dissipation rates specific to a generator and x-ray tube target housing. An x-ray generator is a device that helps to produce x-ray, together with an  x-ray detector, it is commonly used in a variety of applications including Medicine, x-ray, electronic assembly inspection, and measurement of material thickness in a manufacturing operators. Types Of X-ray Generators   • Single Phase Generators  • Three Phase Generators  • High-frequency Generators  • Constant Voltage Generators  - Single Phase Generators : - (also known as single alternator) is an alternating current electric generator that produce a single, continuously alternating voltage. - Three Phase Generators : - work by producing three separate waves of AC power that operate in a sequence ensuring that there is always a continuous flow of energy and that’s the power level nev
