질문 # 24
What is the primary reason lateral resolution varies at different depths?

A. Tissue texture
B. Pulse length
C. Acoustic impedance
D. Beam width

정답：D

설명：
Comprehensive and Detailed Explanation From Exact Extract:
Lateral resolution is determined by the beam width perpendicular to the ultrasound beam's axis. As depth increases, the beam width changes due to beam divergence after the focal point. Narrower beams (better focusing) provide improved lateral resolution at specific depths.
According to sonography instrumentation reference:
"Lateral resolution depends on the width of the ultrasound beam. The narrower the beam at a particular depth, the better the lateral resolution." Therefore, the correct answer is A: Beam width.

질문 # 25
Which feature is a characteristic of continuous wave Doppler?

A. Aliasing
B. Low thermal index
C. Range specificity
D. Dedicated transmit and receive crystals

정답：D

설명：
Continuous wave Doppler uses two crystals - one for transmitting and one for receiving ultrasound waves continuously. This allows for the measurement of high velocities without aliasing, a common limitation in pulsed wave Doppler. However, continuous wave Doppler does not have range specificity, meaning it cannot precisely determine the depth from which the Doppler signal is returning.

질문 # 26
What results from increasing the packet length when using color Doppler imaging?

A. Increased aliasing
B. Decreased frame rate
C. Increased color noise
D. Decreased penetration

정답：B

설명：
Increasing the packet length in color Doppler imaging means increasing the number of pulses used to interrogate each scan line. This improves the accuracy of velocity measurements and sensitivity to low flow velocities but has the drawback of decreasing the frame rate. A longer packet length requires more time to acquire the necessary data, which reduces the number of frames that can be processed and displayed per second. Consequently, while color Doppler imaging becomes more precise, the temporal resolution (frame rate) decreases.References:

질문 # 27
Which artifact is seen as a result of an increase in echo amplitude in the tissue located distal to an anechoic structure?

A. Reverberation
B. Comet tail
C. Mirror image
D. Enhancement

정답：D

질문 # 28
In this image, which characteristics of flow are represented by the upper right side of a variance mode color map?

A. Higher velocity, turbulent with a positive Doppler shift
B. Higher velocity, turbulent with a negative Doppler shift
C. Higher velocity, laminar with a positive Doppler shift
D. Higher velocity, laminar with a negative Doppler shift

정답：A

설명：
In a variance mode color map, the upper right side typically indicates higher velocity and turbulent flow with a positive Doppler shift. Variance mode maps are designed to display not only the mean velocity and direction of blood flow but also the presence of turbulence. The color green is often used in the upper right quadrant to represent areas of turbulence with positive Doppler shifts, which occur when the blood flow is moving towards the transducer at higher velocities and with increased chaotic motion.
