AURR ECHOCARDIOGRAPHY EXAM
QUESTIONS WITH CORRECT VERIFIED
ANSWERS 2026/2027 LATEST UPDATE
In a sector image, the number of scan lines per degree of the sector
determines - CORRECT ANSWER>>>>line density
increasing the line density will # of pulses per frame, improve
spatial resolution (axial and lateral), frame rate and temporal
resolution. increase/decrease? - CORRECT ANSWER>>>>increases,
decreases, decreases
increasing sector angle will have spatial resolution and
temporal resolution. degraded/improved? - CORRECT
ANSWER>>>>improved, degraded
decreasing sector angle will spatial resolution and
temporal resolution. degrade/improve - CORRECT
ANSWER>>>>degrade, improve list 2 types of spatial resolution -
CORRECT ANSWER>>>>axial and lateral
