What is Knobology in ultrasound?
Knobology is a terminology that describes the manipulation of ultrasound knobs and system controls in order to obtain the best image possible from diagnostic ultrasound. The inadequate use of knobology variables may impair image quality and can result in misdiagnosis.
What is B mode in ultrasound stand for?

- Use the Near, Mid, and Far sliders to adjust the image as needed by tapping a slider and moving your finger right or left to increase or decrease the percentage.
What does red mean on an ultrasound?
Vessels in which blood is flowing are colored red for flow in one direction and blue for flow in the other, with a color scale that reflects the speed of the flow. Because different colors are used to designate the direction of blood flow, this Doppler technique simplifies interpretation of the ultrasound data.
