Factors Affecting Frame Rate in Imaging

Which of the following factors affects the frame rate in imaging?

• Imaging depth

• Speed of sound in the medium

• Temperature of the medium

• Pressure of the medium

Which system settings affects the frame rate?

• Imaging depth

• Frequency of sound

• Number of pulses per frame

• Speed of light

In shallow imaging, what is the characteristic of the go-return time?

• Long go-return time

• Short go-return time

• Variable go-return time

• Constant go-return time

Which type of imaging has a higher frame rate?

• Deep imaging

• Shallow imaging

• Both have the same frame rate

• Neither has a frame rate

What is the temporal resolution like in deep imaging?

• Superior temporal resolution

• Inferior temporal resolution

• Equal temporal resolution

• No temporal resolution

What is the effect of increased depth (deep imaging) in ultrasound imaging?

• Short go–return time, shorter T frame, higher frame rate

• Long go–return time, longer T frame, lower frame rate

• Short go–return time, longer T frame, lower frame rate

• Long go–return time, shorter T frame, higher frame rate

What does shallower imaging require in terms of listening time?

• More listening time

• Less listening time

• The same listening time

• No listening time

Which of the following factors determines the number of pulses per frame in ultrasound imaging?

• Frequency of the transducer

• Number of focal points

• Line density

• Sector size

What is a characteristic of single focus in ultrasound imaging?

• Many pulses per scan line

• Longer T frame

• Higher frame rate

• Inferior lateral resolution

What is a characteristic of multi-focus in ultrasound imaging?

• One pulse per scan line

• Shorter T frame

• Superior temporal resolution

• Superior lateral resolution
