Ultrasound Basics Step 12, Part 4 Ultrasound Modes and Probes Self Test What does M-mode stand for? Measure mode Mean mode Motion mode Marvelous mode For Doppler mode to be accurate, the angle between ultrasound beam and path of moving object should be: Perpendicular Parallel Doesn’t matter 45 degrees In order to optimize detection of low velocity flow (like a vein), the velocity scale will need to be changed to: A low velocity scale A medium velocity scale A high velocity scale Which probe would be best to image the jugular veins? Phased array (2-5 MHz) Curved linear array (5-7 MHz) Linear array (7-10 MHz) Microconvex probe (5-7 MHz) The phased array transducer: Is good for superficial vascular structures Can only image 2D and has no Doppler Ideal for cardiac due to its high frame rate Does not have a small footprint to fit in between rib spaces
