Transducer types

What are the 7 types of transducers?

Aka linear array or linear switched array

Operated by applying voltage pulses to groups of elements in succession

What type of transducer uses sequencing, produces a rectangular image, has no steering or focus, and is considered old technology?

What are the advantages of linear sequenced array?

What is the disadvantage of linear sequenced array?

Also called curved, curvilinear, or convex array

Curved line of elements

What type of image does a curved sequenced array create?

What type of transducer has lines that are steered outward by curved design, no focusing, operates by sequencing, and is considered old technology?

What are the advantages of a curved sequenced array transducer?

What are the disadvantages of a curved sequenced array transducer?

Another term for a transducer with multiple elements

This type of transducer operates by applying voltage pulses to groups of elements in succession with small time delays

How many elements does a phased linear sequenced array have?

Linear sequenced array with phasing for focus

If you have a rectangle image you have ______

This transducer can be steered or can have phasing for steering on newer probes, and can be focused by phasing?

Newer probes produce a _______image

What is the advantage of phased linear sequenced array?

What is the disadvantage of phased linear sequenced array?

Also called curvilinear or convex

With a phased curved sequenced array, where are the scan lines steered?

This transducer is identical to phased linear sequenced array, and the scan lines are steered outward, focused by phasing, and has a blunted sector image

What are the advantages of a phased curved sequence array?

What are the disadvantages of phased curved sequence array?

A linear sequenced array (operates by sequencing) and phasing for steering and focus.

This transducer has a sector with a flat top, steers with phasing, and focuses by phasing?

What are the advantages of a vector array?

What are the disadvantages of a vector array transducer?

Also called phased array

This type of transducer operates with phasing, has a sector image with a pointed top, steers by phasing, and focuses by phases?

This transducer produces a sector image with a pointed top?

What are the advantages of the linear phased array?

What are the disadvantages of linear phased array?

Also called annular array

What type of image does a annular phased array produce?

This transducer is ring shaped, multi element, operates like a phased array by using phasing.

What type of transducer produces a sound beam with a cone shape (focused by phasing), and can be focused in the a axis keeping section artifact to a minimum.

What transducer creates a sector image and uses mechanical steering, although it is an electronic transducer?

Can a annular phased array use electronic phasing?

What are the advantages of a annular phased array?

What are the disadvantages of a annular phased array?

What are the two ways a multi frequency transducer performs?

Activates one or the other frequency, uses only 1 frequency at a time, and it chooses which frequency to use.

Aka broad bandwidth mode

Multiple frequencies are transmitted and recieved

Describe a true multi frequency?

Give an example of a state of the art transducer?

State of the art transducers have what type of array?

What is the disadvantage of the matrix array?

With linear arrays, how do you focus the z axis?

What is the benefit of a matrix array?

What is the disadvantage of the matrix array?
