Study Notes
X-Ray Machines
- X-ray machines produce a beam of X-rays that is used to create images of the inside of the body.
- X-rays are a form of electromagnetic radiation that can penetrate soft tissues.
- X-ray machines have a collimator to minimize the field of view.
- The collimator is attached to the x-ray below the glass window where the useful beams are emitted.
- Portable X-ray machines are known for their intuitive and effectual design, and can interface well with other technologies.
- Mobile X-ray machines have a higher output than portable x-ray machines owing to their larger transformers and are mounted on wheels with output of 90-125kv and 40 to 300mA.
Cardiac Procedures
- In cardiac procedures, dye can be injected into the coronary arteries to show blood flow or to investigate potential blockages.
- Catheters may be placed more easily due to fluoroscopic guidance.
