CCI Adult Echo CTL Physics of Ultrasound 16% (COMPLETE SOLUTION)

A highly attenuating structure inhibits the transmission of sound which produces an anechoic area, posterior to the structure known as - Shadowing Increasing sector size increases the - Number of pulses needed to create the image Increasing sector size will decrease the - Frame rate and temporal resolution Spatial resolution will improve with - Increased line density ________________ resolution is the ability to differentiate two reflectors that are perpendicular to the US beam - Lateral ___________________ resolution is the ability to differentiate two reflectors that are parallel to the US beam - Axial __________________ and ________________ are weak off axis portion of the beam that decrease lateral resolution - Grating lobes and side lobes
