The primary function of the X-ray tube is to produce X-rays and direct them towards the patient. It contains the cathode and anode, where X-rays are generated through the interaction of high-energy electrons with a target material.
"kVp" stands for kilovoltage peak. It refers to the maximum voltage applied across the X-ray tube, which determines the energy of the X-rays produced. Higher kVp settings result in more penetrating X-rays and better image contrast.
The control panel of an X-ray machine is used to adjust exposure parameters and settings, such as kVp, milliampere-seconds (mAs), and exposure time. These adjustments help optimize image quality and ensure patient safety.
Regularly checking and calibrating the X-ray machine is crucial for maintaining proper operation and ensuring accurate imaging. This includes verifying the machine’s performance and making necessary adjustments to maintain optimal functioning.
The tube current, measured in milliamperes (mA), controls the quantity of X-rays produced by the X-ray tube. Higher mA settings increase the number of X-rays generated, which affects the image density and contrast.
