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.
