Ultrasound Basic Knobology & Controls
This document provides an overview of ultrasound probe types, imaging modes, and basic controls. It discusses the different types of probes and basic ultrasound imaging modes including B-mode, M-mode, color flow mode, and Doppler mode. For each mode, it lists the main controls and knob functions, and provides guidance on optimizing settings like frequency, depth, gain, and pulse repetition frequency. The document serves as a basic guide to ultrasound machine controls and settings for different imaging applications.

- 6. B-Mode:- 1. Frequency –Higher the Frequency Lower the penetration (2 Mhz to 5.5 Mhz) 2. Grey map – To adjust the varoius grey shades of 2D image.( A to Z) 3. Depth - Less depth will have higher the frame rate (Upto 30 cm) 4. Scan Area (Field of View) – Less Scan area will have more frame rate. 5. Gain – To increase /decrease the brightness of image. 6. Tissue Harmonic Imaging –Gives more penetration and avoid Re Vibrating artifacts 7. Zoom – To magnify the particular region of interest (ROI). 8. Focus Position – It should be always against R.O.I to have better focus. 9. Dynamic Range – It is used to adjust the sharpness of 2D image. 10 .Time Gain Compensation (TGC) – Its used to adjust the gain in the particular ROI

- 12. CF -Mode:- 1. ColorFlow Map – It gives various shades of Color Maps for the user comfort. 2. Color Box - Less Box Size will have more frame rate 3. Box Steer – Always towards the flow especially in Linear probe 4. PRF – Pulse Repetition Frequency - It is used to avoid the aliasing effect 5. Color Flow Gain – To increase /decrease the flow level in the vessel. 6 .Auto Color optimization (AO) – One touch of key will adjust the Color gain by the machine Itself (ACO)
