Ultrasound Physics Chapter 12 2D imaging

What does the term "Field of View" refer to in the context of ultrasound imaging?

• The area depicted by the ultrasound transducer during imaging.

• The frequency of sound waves used in imaging.

• The duration of the ultrasound scan.

• The power output of the ultrasound machine.

What is the "footprint" in the context of a transducer?

• The part of the transducer that meets the body

• The power source of the transducer

• The display screen of the transducer

• The cable connecting the transducer to the machine

What does the footprint of the transducer determine?

• The width of the near field

• The frequency of the ultrasound

• The color of the image

• The length of the cable

How does the shape of the footprint affect the ultrasound image?

• It decides the shape of the image

• It changes the color of the image

• It increases the power of the transducer

• It determines the speed of sound

• Having no crystals at all

• Being used only for sound recording

What is the alignment of crystals in a 1D array transducer?

• In a singular row

• In a circular pattern

• In a triangular grid

• In a random arrangement

• Animated video sequences

• Infrared thermal images

Explain why 1D array transducers, despite having crystals in a single row, can still create 2D images.

• Because the single row can scan across an area to build up a 2D image

• Because each crystal emits a different color

• Because they use multiple rows of crystals

• Because they rotate to capture images from all angles

What is the main advantage of using 1 ½ D array transducers in ultrasound imaging?

• More control of the slice thickness

• Lower cost of manufacturing

• Faster image processing

• Larger image size

How are the crystals arranged in a 1 ½ D array transducer?

• In a minimum of 3 rows

• In a single row

• In a circular pattern

• Randomly distributed
