DEAD ZONE (A1 & A2)
Description and Reason For Testing
The dead zone is the distance from the front face of the transducer to the first identifiable echo at the phantom/
patient interface. The dead zone occurs because an imaging system cannot send and receive data at the same
time. Therefore, no clinical data can be collected in this region. However if artifacts are noted within the dead
zone, they may indicate fluctuations in the input power to the system. The depth of the dead zone depends upon
the frequency and performance of the transducer and the pulsing/receiving section of the system.
