Ultrasound Dynamic Range - Video Lesson

Welcome back to our series on optimizing ultrasound images. This lesson discusses dynamic range, how it can be adjusted during a sonogram, and its effects on the sonographic image. Having a strong knowledge of dynamic range greatly affects the diagnostic quality of your images. Let's start with a basic definition of dynamic range and how it is measured. Dynamic range refers to the range of echo signal amplitudes that an ultrasound system can display, from the weakest to the strongest signals as shades of gray. Think of a photographer trying to photograph a landscape on a sunny day. She makes adjustments to the camera's aperture and chooses a lower ISO to get a wide dynamic range and capture the bright sky and shaded trees with equal detail. Dynamic range is measured in decibels or dB, and it's essential for representing the wide variations in echo amplitudes, which return to the trans
