Ch 13 Physics Part 1

What is real-time imaging often compared to?

• A still photograph

• A motion picture

• A painting

• A sculpture

What impression is provided by the quick creation and display of each frame in ultrasound imaging?

• Constant motion

• Still images

• Slow motion

• Blurred vision

What is the most important operational parameter mentioned in the document?

• Resolution

• Frame Rate

• Color Depth

• Contrast

How is frame rate defined in the document?

• The number of colors displayed each second

• The number of frames or images created each second

• The number of pixels in an image

• The number of sound waves per second

What is associated with an ultrasound "movie"?

• The system's ability to create numerous frames each second

• The system's ability to enhance color

• The system's ability to increase resolution

• The system's ability to reduce noise

What is the relationship between frame rate and the time required to make a single image (T Frame)?

• They are directly proportional.

• They are inversely related.

• They are unrelated.

• They are equal.

If it takes more time to make each image, what happens to the frame rate?

• The frame rate increases.

• The frame rate decreases.

• The frame rate remains constant.

• The frame rate doubles.

What is the formula that represents the relationship between T frame and frame rate?

• T frame + frame rate = 1

• T frame - frame rate = 1

• T frame x frame rate = 1

• T frame / frame rate = 1

If an ultrasound system creates an image in 1/10 of a second, what is the frame rate?

• 5 frames/second

• 10 frames/second

• 15 frames/second

• 20 frames/second

What is the unit of measurement for frame rate?

• Meters per second

• Kilometers per hour

• Hertz (Hz)

• Seconds per frame
