Your answers are highlighted below.
Question 1
What denotes the distance for a wave to complete a cycle?
A
Period
B
Wavelength
C
Cycle
D
Frequency
Question 1 Explanation: 
How far does the wave travel before it starts a new cycle. If it goes farther, longer wavelength, your frequency will be less. Takes longer for a wave to complete so you can't make as many.
Question 2
A reflection from a boundary where the variations on the surface are smaller than the pulse wavelength will be what type?
A
Rayleigh.
B
Total.
C
Partial.
D
Specular.
Question 2 Explanation: 
The the beam it appears smooth and will reflect almost all the energy.
Question 3
The artifact that results from an ultrasound beams finite and measurable three-dimensional profile is called what?
A
Multipath artifact
B
Acoustic speckle
C
Slice artifact
D
Grating lobe artifact
Question 4
Q-factor is related to bandwidth how?
A
Directly.
B
Inversely.
C
Factor of 5/9.
D
They are independent of each other.
Question 4 Explanation: 
Q factor relates to how damped an oscillator is. If it's not damped it will ring like a bell with many different frequencies. If it is damped it will be limited to a few frequencies. So as Q factor (damping) increases, bandwidth decreases.
Question 5
The propagation speed that we use in the doppler equation is what?
A
4,080 m/s - The speed of sound in bone.
B
330 m/s - The speed of sound in gas.
C
1,570 m/s - The speed of sound in blood.
D
1,540 m/s - The speed of sound in soft tissue.
Question 5 Explanation: 
You could almost think that the propagation speed in blood would be a factor but the beam spends most of the time in soft tissue.
Question 6
The term Homogenous in relation to a sonographic image means?
A
When the imaged structure has a non-uniform, uneven appearance
B
When the imaged structure has a smooth, uniform appearance
C
A structure that appears lighter than the surrounding structures
D
A structure that appears darker than the surrounding structures
Question 6 Explanation: 
The prefix Homo- means "the same"
Question 7
Acoustic speckle is an artifact produced by what?
A
Accurate display of tiny reflectors.
B
Large reflectors in the medium.
C
Resonance of particles in the near field.
D
Interference of tiny acoustic wavelets.
Question 8
A vector transducer gives a what type of display format?
A
Continuous wave
B
Trapezoidal
C
Curved
D
Rectangular
Question 8 Explanation: 
A vector transducer is a sector transducer except for the fact that the image does not come to a point. It's shape is trapezoidal as opposed to a straight sector which is wedge shaped.
Question 9
Side lobes usually display which artifact?
A
Single reflectors appearing in multiple locations on the image.
B
Reflectors appearing too deep on the image.
C
The bending of the sound beam due to difference in acoustic impedance.
D
Hollow structure's appearing anechoic on the image.
Question 10
If the frame rate increases the time to generate a single frame...?
A
Decreases
B
Is halved
C
Increases
D
Stays the same
Question 10 Explanation: 
These are inversely proportional. If you image something a centimeter under the skin. The echo returns quickly so a new frame can be made quickly. In one second you can make more frames. So there a more frames per second displayed.

    HELLO;
    I JUST AMAZING FOR THIS WEBSIDE…ITS INCREDIBLE HOW YOUR WEBSIDE WORKS,AMAZING PRICES.THANK YOU, FROM THE BOTTOM OF MY HEARTH…ITS GREAT STUDY SKILL TO PREPARED FOR ARDMS EXAM.THANK YOU
    SINCERLY,
    ELIZABETH VARGAS

    • It’s my pleasure. We hope to be able to help as much as we can. Feel free to send us a message if there is anything we can help with. Also if there is a concept that maybe we could explain or cover a little more. We want to have the best material to prepare you.

  2. Elaine Covaleski says:

    Yes, I agree this website is very helpful. Still will need prayers though to pass this test!! LOL.

    • Good luck. You’ll do great. Let me know if I can do anything to help.

      • Elaine Covaleski says:

        Awe, thank you sooo much. I took my physics part of US months ago but they told me to hold off on the SPI test. I wish I took it back then. I’ve forgotten so much of it.

  3. Elaine Covaleski says:

    I’ve heard so many horror stories of people failing it. I really want to pass it the first time around.

  4. Elizabeth Vargas says:

    Hi… If. You study. Every day with flascard. And this amazing web side. You. Will. Be. Master. The study. Material. …. I. Use this web side. To. Gain confident. That. I. Learned the question and answer… I’m. Preparing. For the Ardms. State. Test.. GOOD LUCK

    I am 21 yrs old i finished th eultrasound program in 2010 when i was 19 i have fallen off the wagon of studying this do to a lack of jobs available! but can anyone spare some notes and hints? i would appriciate it alot!
