Beam Quantity II - Video Lesson

Hey everybody. Welcome back. This lesson continues our discussion of characteristic of the x-ray beam called beam quantity. You should remember that beam quantity refers only to the total number of photons in the x-ray beam, not their energies. Beam quantity is also known as beam intensity. The x-ray beam quantity or intensity is influenced by several factors, including the milli amperage, that's the MA, exposure time, KVP, distance, and filtration. In this video, we're going to focus on the factors of distance and filtration. In this context, distance refers to the distance between the x-ray source and the point where we're measuring the beam quantity. Beam quantity and distance are inversely related. In other words, as distance increases, the beam
