Study Notes
Radiography
- Radiography, commonly known as X-ray, is used to visualize bones.
- X-rays, a type of ionizing radiation, are used in radiography.
X-ray Interaction
- When X-rays interact with atoms, they are absorbed or scattered, resulting in a varying degree of attenuation.
Image Formation
- Dense structures in the body, such as bones, absorb more X-rays and appear lighter on the image.
- Residual X-rays, which are not absorbed, form the image on the detector.
Computed Tomography (CT) Scan
- A CT scan is a non-invasive imaging technique that uses X-rays to produce detailed cross-sectional images of the body.
CT Scan Components
- The movable table in a CT scan allows the patient to be positioned correctly and moved smoothly during the scan.
- Detectors in a CT scan convert X-rays into digital signals that are used to reconstruct the image.
Contrast Agents
- Injecting a contrast product, such as iodine, during a CT scan enhances the visibility of certain structures and improves image quality.
Clinical Applications
- CT scans are commonly used in oncology to control the response to chemotherapy and monitor tumor progression.
