In radiology, the x-ray yield is the percentage of tube power transformed into radiation.
A high amount of the tube power is used to warm up the target. A higher tube voltage results in a linear increased x-ray yield. The transformation of tube power depends also on the atomic number of the target material. The higher the atomic number, the better the x-ray yield. Tungsten (the most common target material) in combination with a tube voltage of 100kv provides an x-ray yield of 0.7%.

(DQA) This procedure is used by system operators to verify an x-ray system, gamma camera, or CT scanner operation based on relevant image quality parameters like e.g., geometric distortion, x-ray yield, signal to noise ratio. The quality assurance should carry out according to instructions of the manufacturer.

The latitude is the range between the minimum and maximum x-ray exposure to an image receptor that yields a diagnostic image of structures.
