Thyroid Ultrasound Transducer

Hello. my name is claire hammond. and this is Sue Thomas. And we’re general imaging application specialists. for the Philips UK ultrasound team. Today, we will be showing you how to perform an elastography strain study. on the Philips EPIQ ultrasound system.

So now we’re going to look at strain elastography. Strain elastography is a simple, noninvasive, realtime imaging technique. It provides a display overly with stiffness information over a greyscale image. You can use strain elastography in the breasts, to assess the stiffness of a lesion. It is also possible to use it in other areas, like the neck and for MSK. Firstly, select either the L125 or the L185 transducer, and the appropriate presets.

When you would like to start using the elastography. press the Elasto icon on the touchscreen. The screen will split with the 2D image on the lefthand side. and the elasto image on the righthand side. You can also press the SidebySide button. to have a single screen elastogram image.

You can change the size of the elasto box. by using the buttons around the trackball. The elasto image should include the area of interest and some normal tissue. On the rotary key, you can select to show just the elastogram. have the images blended with the 2D image. or just have the 2D image.

There is a green compression bar on the righthand side of the screen. The user should keep their hand still and with a constant pressure. and allow the patient’s cardiac or respiration movement to provide the strain. There are eight different elastography color maps. The most popular color map shows stiff areas as red. and soft areas as blue.

However, you can change the map to suit your preference. There is a size compare feature, which allows you to compare a measurement. on the 2D image and on the elastogram. This is a useful feature when assessing malignant lesions. to see if there is any infiltration to the surrounding tissues. To carry out a size compare measurement.

Freeze the image. press Size Compare on the touchscreen. measure the lesion on the 2D image. and press copy on the touchscreen. and the measurement is copied onto the elastogram. Some tips for successful strain elastography image include.
