Transducers

Question 1

What is the general frequency for a curved probe and what is it used for?

Answer 1

approx 3-5Mhz. used for: abdomen, pelvic & obstetrics or any situation where depth of view is important

Question 2

What is the general frequency for a endovaginal/transvaginal probe and what is it used for?

Answer 2

approx 8Mhz. and used for intercavity scanning - rectal and vaginal imaging. Can use a higher frequency for intercavity imaging because we are closer to the structures (don’t need as much depth) and we can have better image resolution

Question 3

what approx frequencies can you get the linear probes and what are they used for?

Answer 3

different frequency types - one with a much higher frequency (approx 12-18Mhz) and used for very superficial structures such as: breasts, thyroids, testes & musculoskeletel exams. The other probe is still a higher frequency but much less than the last one, approx 7Mhz and used for vascular applications & superficial structures

Question 4

what do you use a 12-18Mhz linear probe for?

Answer 4

VERY superficial structures that need high resolution. Such as: breasts, thyroids, testes & musculoskeletal exams

Question 5

what do you used a 7Mhz linear probe for?

Answer 5

vascular applications & superficial structures

Question 6

what do you use a 3-5Mhz curve probe for?

Answer 6

abdomen, pelvics & obstetrics or any situations where depth of view is important. The lower frequency allows us to scan deeper but it does reduce image quality

Question 7

What is the general frequency for a sector probe and what is it used for?

Answer 7

generally around 4-11Mhz and used mostly for echocardiography
