4. Image Orientation
Sagittal (or longitudinal) images
The superior or head end of the patient is
to the viewer’s left side

5. Image Orientation
Transverse images
The image is viewed as if you are
positioned at the patient’s feet, looking up

6. Trasducer
2.5 MHz: deep abdomen, obstetric and gynecological imaging
3.5 MHz: general abdomen, obstetric and gynecological imaging
5.0 MHz: vascular, pelvic imaging
7.5 MHz: thyroid
10.0 MHz: thyroid, superficial veins, superficial masses,
musculoskeletal imaging.
15.0 MHz: superficial structures, musculoskeletal imaging

7. Gynecology and Obstetric
Gynecologic ultrasonography examines female pelvic organs
(specifically the uterus, the ovaries, and the Fallopian tubes) as well
as the bladder, the adnexa, and the Pouch of Douglas.
Obstetrical sonography is commonly used during pregnancy to check
on the development of the fetus.

Transducer
For very early pregnancies
(e.g. less than 6w)
high frequency endocavity
transducer
For scans above 6w curved 1 – 6 MHz transducer

11. Gastroenterology
Abdominal ultrasound are frequently used in gastroenterology
surgery.
The solid organs of the abdomen such as
the pancreas, aorta, inferior vena cava,
liver, gall bladder, bile ducts, kidneys, and spleen are imaged.

14. Angiology (vascular)
Can be performed on many vessels throughout the body, but not all
Use B-mode ultrasound with Doppler techniques
can’t be seen vessels in the brain
Vascular ultrasound

15. Cont.
Transducer
High frequency,linear
transducers
Superficial vessels, for example in
the arms, legs and neck
Lower frequency, curved
transducer
Deeper vessels, such as those in the
abdomen

16. Vascular waveforms
Arterial flow demonstrates a pulsatile flow
Recorded on the horizontal time axis
Biphasic-high and a low velocity point
Traditionally colored red on sonography
Demonstrated above the horizontal time
axis

Monophasic flow
Does not exhibit a pulsatile flow
Same velocity all the time
Traditionally colored blue on sonography
Demonstrated below the baseline

masses, and bone surfaces
To visualize real-time soft tissue motion
Continuous display of tissue, acquired at over 50 frames per second
