ARDMS Sonography Principles and Instrumentation Sample Questions (Q93-Q98):

NEW QUESTION # 93
Which target group is used to evaluate transverse distance measurement accuracy in this tissue-mimicking phantom image?

A. Option D
B. Option A
C. Option B
D. Option C

Answer: A

Explanation:
In the tissue-mimicking phantom image, Option D (blue box) is used to evaluate transverse distance measurement accuracy. Phantoms are used to simulate human tissue and provide a standardized way to test the accuracy and precision of ultrasound machines. Transverse distance measurement accuracy is assessed by measuring known distances between targets in the phantom. The blue box (Option D) typically contains targets positioned to specifically test the accuracy of transverse measurements, ensuring that the ultrasound system provides reliable and precise distance readings.

NEW QUESTION # 94
Which effect does spatial compounding have on ultrasound images?

A. Increases propagation speed
B. Decreases shadowing
C. Decreases propagation speed
D. Increases shadowing

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Spatial compounding acquires multiple frames from different angles and combines them into a single image.
This technique reduces the appearance of artifacts such as shadowing and speckle noise, resulting in a smoother, more uniform image.
According to sonography instrumentation reference:
"Spatial compounding reduces artifacts like posterior shadowing and speckle by averaging data from multiple insonation angles." Therefore, the correct answer is D: Decreases shadowing.

NEW QUESTION # 95
Which artifact displays reflectors more shallow than their actual position?

A. Range ambiguity
B. Section thickness
C. Ring-down
D. Mirror image

Answer: A

Explanation:
Range ambiguity artifact occurs when echoes from one pulse are received after the next pulse has been emitted, leading to the incorrect placement of echoes at shallower depths than their true location. This artifact typically happens when the PRF is set too high, causing the ultrasound system to interpret delayed echoes as coming from the current pulse rather than the previous one. This results in reflectors appearing closer to the transducer than they actually are.

NEW QUESTION # 96
What produces increased attenuation within soft tissue?

A. Higher intensity of the ultrasound beam
B. Higher frequency of the ultrasound beam
C. Lower intensity of the ultrasound beam
D. Lower frequency of the ultrasound beam

Answer: B

Explanation:
Attenuation refers to the reduction in the intensity of the ultrasound beam as it travels through tissue. Higher frequency ultrasound beams experience more attenuation because they are absorbed and scattered more than lower frequency beams. This is due to the fact that higher frequency waves have shorter wavelengths and interact more with the small particles in tissues, causing greater energy loss.
Reference: ARDMS Sonography Principles and Instrumentation, Chapter on Ultrasound Physics and Instrumentation.

NEW QUESTION # 97
What is the primary factor that affects axial resolution?

A. Aperture
B. Speed of sound
C. Spatial pulse length
D. Focal zone

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Axial resolution refers to the ability to distinguish two structures that are located along the path of the ultrasound beam. It is directly related to the spatial pulse length (SPL), which is the product of the number of cycles per pulse and the wavelength. A shorter SPL leads to better axial resolution.
According to sonography instrumentation reference:
"Axial resolution improves as spatial pulse length decreases because shorter pulses can better differentiate structures lying close together along the beam axis." Therefore, the correct answer is B: Spatial pulse length.
