Plain Radiograph/X-ray in Medical Imaging

Plain radiograph/X-ray is a fundamental tool in medical imaging that utilizes X-rays to create images of the human body. It provides fast, high-resolution, low-cost images without requiring special patient preparation. Components include the X-ray tube, detector, anti-scatter grid, couch, Bucky table, and silver halide film, each playing a crucial role in capturing detailed images. This imaging technique is commonly used to visualize various body parts such as the chest, arms, legs, spine, bones, and joints.

2. Plain Radiograph/X-ray / Definition of plain radiograph/X-ray Properties of plain radiograph/X-ray Component of plain radiograph/X-ray system How the plain radiograph/x-ray is formed on the silver halide film ? 2

3. Plain Radiograph/X-ray Definition of plain radiograph/X-ray / It is medical imaging of the different parts human body Using X-rays It is represent the simplest medical images created using X-radiation The medical image is produced by passing the X-ray through a human body , according to the density and composition of the bone or tissues

4. Plain Radiograph/X-ray Properties of plain radiograph/X-ray (i) Simplest medical images created using X-radiation (ii) Provides fast (iii) High-resolution images (iv) Low-cost (v) Does not require special preparation for the patient (vi) plain X-rays system can provide medical imaging of different parts of human body , as chest , arms , legs ,spine , bones and joints 4

6. Plain Radiograph/X-ray Component of plain radiograph/X-ray system / (i) X-ray tube ( ) (ii) X-ray detector (receptor) (iii) Anti-scatter grid (iv) Couch (v) Bucky table (vi) Silver halide film Silver halide film (vii) Control unit

7. Plain Radiograph/X-ray Component of plain radiograph/X-ray system i) X-ray tube is an electrical device used for generation of X-ray, which constant from glass tube, cathode, and anode. ) ( ii) X-ray detector (receptor) are devices used to measure the flow amount and distribution of X-rays. iii) Anti-scatter grid is a device placed between the patient and the receptor, which will transmit the radiation but reject the scatter radiation iv) Couch : it represent the bed used to sleep the patient v) Bucky table : it represent the x-ray cassette place of silver halide film vi) Silver halide film: it represent the film that shows the medical image consisting of silver bromide (AgBr). This film when exposed to light, produces a silver ion (Ag+) and an electron, and it convert to dark color vii) Control unit: X-ray systems have a control on plain radiograph/X-ray system.

8. X-ray tube Plain Radiograph/X-ray patient Couch How the plain radiograph/x-ray is formed on the Control unit silver halide film ? - The photons of x-ray emitted by the X-ray tube enter the body of patient. Buckytable (silver halide film) - Patient is placed between X-ray tube and silver halide film. - X-rays that passed through the body are absorbed or transmitted in direct to bone or tissue. Silver halide film - More exposure of silver halide film to x-ray lead to be more dark - Bone represents the highest to absorb X-rays photons. So, the silver halide film will be more white - Soft tissues represents the lowest to absorb X-rays photons. So, the silver halide film will be more dark Medical image

B) A method for creating complex medical images C) A form of magnetic resonance imaging D) A technique for ultrasound imaging E) None of them What does the anti-scatter grid do in the radiograph system? A) Generate X-rays B) Measure X-ray flow C) Transmit radiation while rejecting scatter radiation. D) Position the patient E) Control X-ray exposure time How is the couch utilized in the radiograph system? A) Generate X-rays B) Measure X-ray flow C) Reject scatter radiation D) Position the patient. E) Control X-ray exposure time What is the composition of silver halide film used in radiography? A) Silver iodide (AgI) B) Silver nitrate (AgNO3) D) Silver chloride (AgCl) C) Silver bromide (AgBr). E) Silver oxide (Ag2O) 10
