SHOULDER X-RAY

The basic projections are A.P and lateral oblique

➢ Antero posterior (A.P):- The patient laid supine or erect, and slightly rotated to the affected side approximately 15° degrees. 

The opposite side should be supported with pad when the supine position is used, the arm should be extended and the hand rotated outwards so that the palm is facing the tube.


Centering point: - Center 1inch (2.5cm) inferior to the coracoids process of the scapular.

➢ Lateral oblique: - from the previous position the arm and forearm should be abducted and flexed the elbow joint, with the forearm across the abdomen, and the forearm supported with the other hand.


Centering point: - Center to the head of the humerus.





Essential image characteristics,

The image should demonstrate the bones of the shoulder joint clearly, head of the humerus and the end of acromion and part of the scapula.

X-ray Generators

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 ene...

Angiography

  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 conge...

HAND X-RAY

The basic projections are P.A and Lateral , ➢ Postero anterior (Dorsi-palmar P.A):- The patient is seated along side the table, the forearm is placed pronated on the table with the palmar surface of the hand in contact with the cassette. With the fingers slightly separated and extended to ensure that they remain in contact to the cassette. Centering point: - Center to the head of the third metacarpopalangeal joint. ➢ Dorsi-palmar oblique: - From the PA position the patient will now rotate his/her hand approximately 45° degrees, ➢ Another modified 15° degrees, Centering point: - Center to the 4th metacarpal bone. Essential image characteristics, The image should demonstrate the bones clearly and soft tissue outline no rotation or motion. References: MIT. Abdussalam A.
