  • 2. 

    The inside of an ultrasound probe consists of?

    • Sound generating polymer

    • Crystals

    • Liquid

    • Magic

    Correct Answer
    A. Crystals
    Explanation
    The inside of an ultrasound probe consists of crystals. Crystals are used in ultrasound probes to generate sound waves. When an electric current is applied to the crystals, they vibrate and produce sound waves. These sound waves then travel through the body and bounce back, creating echoes that are detected by the probe. The crystals are essential for the functioning of the ultrasound probe as they are responsible for generating and receiving the sound waves used in ultrasound imaging.

    B-mode ultrasound is?

    • Boring mode

    • Grey scale imaging mode

    • Color flow mode

    Correct Answer
    A. Grey scale imaging mode
    Explanation
    B-mode ultrasound refers to grey scale imaging mode. This mode is used to produce a two-dimensional image of internal structures in the body. It uses varying shades of grey to represent different tissue densities, allowing for visualization and evaluation of organs, tissues, and abnormalities. B-mode ultrasound is commonly used in medical diagnostics for assessing various conditions and guiding medical interventions.

    The purpose of ultrasound gel is?

    • Improve your image

    • Improve probe contact

    • Provide a medium for sound transmission

    • All of the Above

    Correct Answer
    A. All of the Above
    Explanation
    Ultrasound gel serves multiple purposes. Firstly, it helps to improve the image quality by reducing air gaps between the skin and the ultrasound probe, resulting in clearer and more accurate images. Secondly, it enhances probe contact by providing a medium that allows the probe to glide smoothly over the skin, ensuring proper and consistent contact. Lastly, the gel acts as a medium for sound transmission, allowing the ultrasound waves to travel efficiently between the probe and the skin, enabling effective imaging. Therefore, the correct answer is "All of the Above."

    Anechoic structures are? An example of anechoic tissue is?

    • Very reflective and bright, fat

    • Very reflective and bright, fluid

    • Not reflective and back, fat

    • Not reflective and dark, fluid

    Correct Answer
    A. Not reflective and dark, fluid
    Explanation
    Anechoic structures are not reflective and dark, fluid. Anechoic refers to the absence of echoes, meaning that these structures do not reflect sound waves back to the source. They appear dark on imaging because they do not reflect the ultrasound waves, and they are filled with fluid which further contributes to their dark appearance. An example of anechoic tissue could be a cyst, which appears as a dark, fluid-filled structure on ultrasound imaging.

  • 6. 

    Hyperechoic structures are? An example of a hyperechoic tissue is?

    • More reflective and bright, fat

    • More reflective and bright, fluid

    • Less reflective and dark, fat

    • Less reflective and dark, fluid

    Correct Answer
    A. More reflective and bright, fat
    Explanation
    Hyperechoic structures are characterized by being more reflective and bright on ultrasound imaging. An example of a hyperechoic tissue is fat, which appears bright and reflective on the ultrasound image.

    Ultrasound is a form of what kind of energy?

    • Thermal

    • Mechanical

    • Radiation

    • Electric

    Correct Answer
    A. Mechanical
    Explanation
    Ultrasound is a form of mechanical energy. Unlike thermal energy, which is related to heat, mechanical energy involves the movement or motion of objects or particles. Ultrasound waves are created by mechanical vibrations and travel through a medium, such as air or water, by causing particles in the medium to vibrate. This mechanical energy is then used in various applications, such as medical imaging or cleaning processes.

    Which transmits ultrasound waves better?

    • Water

    • Air

    • Bone

    Correct Answer
    A. Water
    Explanation
    Water transmits ultrasound waves better than air and bone. This is because water is denser than air, allowing sound waves to travel more efficiently through it. Additionally, water has a higher acoustic impedance, which means it can transmit sound waves with less reflection and loss of energy. Bone, on the other hand, is a solid material that is less capable of transmitting ultrasound waves compared to water and air.

    Ultrasound images are based on reflection of ultrasound waves. What probe position (relative to a structure) gives the best image quality of a structure?

    • Parallel

    • Perpendicular

    • 45 degrees

    Correct Answer
    A. Perpendicular
    Explanation
    The best image quality of a structure in ultrasound imaging is achieved when the probe position is perpendicular to the structure. This is because when the ultrasound waves hit the structure at a perpendicular angle, they are reflected back directly to the probe, resulting in a clearer and more detailed image. If the probe is positioned parallel or at a 45-degree angle to the structure, the ultrasound waves may be deflected or scattered, leading to a lower image quality.

    Ultrasound has never been demonstrated to cause negative biologic effects.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Ultrasound has been extensively studied and there is no conclusive evidence to suggest that it causes negative biologic effects. Numerous research studies and clinical trials have been conducted, and they consistently indicate that ultrasound is safe for diagnostic imaging purposes. The frequency and intensity of ultrasound waves used in medical imaging are carefully regulated to ensure they do not harm the body. Therefore, it can be concluded that ultrasound has never been demonstrated to cause negative biologic effects, making the answer "True" correct.

    You should use the highest frequency probe that allows for the desired penetration.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Using the highest frequency probe that allows for the desired penetration is important because higher frequency probes have shorter wavelengths, which allows them to produce higher resolution images. This means that they can provide more detailed information about superficial structures. However, higher frequency probes have reduced penetration depth, so they may not be suitable for imaging deeper structures. Therefore, it is necessary to choose a probe with a frequency that balances the desired penetration depth and resolution.

    Generally the probe marker should point to?

    • Patient left and caudal

    • Patient left and cranial

    • Patient Right and caudal

    • Patient Right and cranial

    Correct Answer
    A. Patient Right and cranial
    Explanation
    The correct answer is "Patient Right and cranial" because in medical terminology, the term "cranial" refers to the head or towards the head, while "caudal" refers to the tail or towards the tail. Additionally, when referring to the patient's right or left, it is from the perspective of the person administering the probe. Therefore, the probe marker should point towards the patient's right side and towards the head.
