ARDMS SPI STUDY GUIDE ALREADY VERIFIED A+ How does harmonic imaging improve image quality? ️️Harmonic imaging reduces artifacts by using higher harmonic frequencies, which produce clearer, more detailed images than fundamental frequencies. What is the primary cause of side lobe artifacts? ️️Side lobe artifacts result from unwanted sound beams emitted at angles outside the main beam, potentially causing misleading echoes on the image. How does adjusting dynamic range affect ...
