ARDMS Exam SPI Topic 3 Question 2 Discussion

Actual exam question for ARDMS's Sonography Principles and Instrumentation exam
Question #: 2
Topic #: 3
[All Sonography Principles and Instrumentation Questions]

Which transducer was most likely used to create this image?

Show Suggested Answer Hide Answer
Suggested Answer: A

The image shown is typical of an abdominal ultrasound, which commonly utilizes a curvilinear transducer. Curvilinear transducers have a wider field of view at depth, making them ideal for imaging large structures within the abdomen. These transducers emit a curved beam, allowing for better penetration and a broader field of view, which is necessary for comprehensive abdominal examinations. The curvature of the image, the wide field of view, and the depth of penetration all suggest the use of a curvilinear transducer.

Wait, wait, wait... is this a trick question? What if the answer is 'Endocavity' and it's some kind of... I don't know, a butt-scan or something? *chuckles*

Nah, I think it's a linear array. The image has that distinct rectangular shape that's typical of linear probes.

I think it might be a phased array transducer, based on the image.

Hold on, I've seen this type of image before. It's gotta be a curvilinear transducer, right? The shape just seems to fit.

Hmm, this looks like an ultrasound image. I'm guessing the transducer used is a phased array - it seems to have the characteristic fan-shaped beam.

I would go with phased array too, the image does have that fan-shaped beam.
