How do radiographers select exposure factors?

How do radiographers select exposure factors?

The primary exposure technique factors the radiographer selects on the control panel are milliamperage, time of exposure, and kilovoltage peak (kVp). Depending on the type of control panel, milliamperage and exposure time may be selected separately or combined as one factor, milliamperage/second (mAs).

What is exposure factor in radiography?

Both intraoral and panoramic x-rays machines have the following exposure factor controls: milliamperage (mA), kilovoltage (kVp) and time. Altering the milliamperage setting influences the quantity of x-rays produced and image density or darkness. …

What is kVp and mAs in radiology?

* kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts. Understanding Technique. kVp stands for kilovoltage peak.

What is a bitewing?

Bitewings are one of the most common sets of X-rays. Bitewings show teeth above the gum line and the height of the bone between teeth. Bitewings help diagnose gum disease and cavities between teeth. The bitewing X-ray is placed on the tongue side of your teeth and held in place by biting down on a cardboard tab.

What are the different types of radiography?

The most common types of diagnostic radiology exams include:

• Computed tomography (CT), also known as a computerized axial tomography (CAT) scan, including CT angiography.
• Fluoroscopy, including upper GI and barium enema.
• Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA)
• Mammography.

Will an xray show gum infection?
