The term that describes the fraction of time that the transducer is actively generating ultrasound waves is Option B. duty factor. It is calculated by dividing the pulse duration by the pulse repetition period and ranges from 0 to 1.
The term that describes the fraction of time that the transducer is actively generating ultrasound waves is the duty factor.
1. Duty factor:
- The duty factor is a unitless value that represents the fraction of time that the ultrasound transducer is actively generating ultrasound waves.
- It is calculated by dividing the pulse duration (the time the ultrasound is transmitted) by the pulse repetition period (the time between consecutive pulses).
- The duty factor ranges from 0 to 1, where a duty factor of 1 means the transducer is transmitting continuously, and a duty factor of 0 means the transducer is not transmitting at all.
- The duty factor is also referred to as the "duty cycle" in some contexts.
Other answer options:
- De rating factor: This term refers to a factor used to adjust the power output of a device under certain conditions, and it is not directly related to the fraction of time that the transducer is actively generating ultrasound waves.
- Pulse repetition period: This term represents the time interval between consecutive pulses and is not specifically related to the fraction of time that the transducer is actively generating ultrasound waves.
- Q-value: This term refers to the quality factor, which describes the damping characteristics of an ultrasound transducer and is not directly related to the fraction of time that the transducer is actively generating ultrasound waves.
