1.	Which transducer is arranged in the shape of a clover leaf so that it provides a large area of illumination?(a) piezo-electric(b) ultrasonic(c) array(d) pressureThis question was addressed to me during an interview.My question is from Oximeters in chapter Oximeters of Biomedical Instrumentation
Answer» The correct option is (b) ultrasonic Explanation: The ultrasonic transducer is arranged in the shape of a clover-leaf so that it provides a LARGE area of ultrasonic illumination which allows the monitoring considerable lateral and descending foetal motion before requiring REPOSITIONING. The transducer housing is flexible to permit it to FOLLOW the contour of the abdomen regardless of shape CHANGES with CONTRACTIONS.
