About MBe

The MBe control turns on SonoMBe™ imaging,

which enhances linear structures within a selected

angle range and can facilitate needle guidance

during catheter placement and nerve-block

procedures. A three- or four-sided outline indicates

the enhancement area. (See Figure 1 on

page 31.)

For curved array transducers, MBe can help identify

the direction of the needle, although only segments

of the needle shaft may show in the image. (See

Figure 2 on page 32.) Use movement and fluid

injection to help verify the needle-tip location.

The MBe control is available in full-screen imaging

only and on the following:

• Transducers: C60x, HFL38x, HFL50x, L25x,

L38xi

• Exams: Breast, Musculoskeletal, Nerve, Small

Parts, Vascular (L25x only), Venous (L25x

only)

WARNING:

To avoid incorrect needle

placement when MBe is on:

• Using movement and fluid

injection, verify the needle-tip

location and trajectory. MBe

enhances linear structures within

a selected angle range on the

ultrasound plane. Linear

structures outside the selected

angle range or the ultrasound

plane

—such as a bent

needle

—may be less apparent.

• Note that linear structures are

enhanced only in an outlined

portion of the image. The area

outside the outline remains

unchanged. (See Figure 1 on

page 31.)

• Note that the beam divergence

of a curved array transducer may

prevent a segment of the needle

shaft from showing in the image.

(See Figure 2 on page 32.) The

needle tip may not show.
