Frequently Used Functions

Switching the Frequency

Press the Frequency [+] or [–] key to switch the ultrasound

transmission frequency.

This cannot be changed when using THE mode.

Adjusting Gain / Contrast

Press the [+] or [-] key for Gain or Contrast.

Turning the s-FOCUS On

s-FOCUS is a function that reduces the change in resolution with distance from the ultrasound transducer

surface (focus-dependent) by combining the received signals obtained from multiple transmissions

(aperture synthesis processing).

· This cannot be turned on or off while an ultrasound image is frozen.

· When s-FOCUS is turned on, the focus mark (leftward triangle “

” mark)

on the monitor display switches to the focus area mark (downward

triangle “ ” mark above the ultrasound image and upward triangle “ ”

mark below it).

* Cannot be performed in CHE.

Turning Enhance On Switching to THE Mode

THE (THE-P / THE-R)

This uses the harmonic component bounced back from

the tissue for imaging.

Press the mode selector buttons to switch the mode.

THE-P THE mode that prioritizes penetration depth.

THE-R THE mode that prioritizes resolution.

Press a button in

ENHANCE section and

turn on ENHANCE.

STRUCTURE ENHANCE

Image processing that reduces speckle noise while

highlighting the boundaries of structures. Processing level

can be adjusted with the [+] or [–] key for Adjust key 1.

ECHO ENHANCE

Image processing that increases the overall contrast of

an image while reducing noise.

BRIGHTNESS ENHANCE

Image processing that increases contrast while

maintaining the brightness level of the entire image.

Adjusting the Display Range

Adjustable depth/range is variable depending on the type of product connected.

Ultrasound Probe: 2, 3, 4, 6, 9 & 12cm

Ultrasound Endoscope: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 & 12cm

Press the DEPTH/RANGE or key.

key: DEPTH/RANGE becomes smaller.

key: DEPTH/RANGE becomes larger.

ENDOSCOPIC ULTRASOUND CENTER OLYMPUS EU-ME3

Need help?

Do you have a question about the Olympus EVIS EUS EU-ME3 and is the answer not in the manual?

The Olympus EVIS EUS Endoscopic Ultrasound Center EU-ME3 is a sophisticated medical device designed for endoscopic ultrasound imaging, offering a range of functions to optimize image quality, facilitate measurements, and enhance user interaction.

Image Acquisition and Enhancement

Switching the Frequency: The device allows users to switch the ultrasound transmission frequency using the [+] or [-] keys. This feature is crucial for adapting the imaging to different tissue depths and desired resolutions. However, frequency adjustment is not possible when operating in THE mode.

Adjusting Gain / Contrast: Users can adjust the gain and contrast of the ultrasound image using the [+] or [-] keys. Gain controls the overall brightness of the image by amplifying the received signals, while contrast enhances the difference between light and dark areas, improving the visibility of structures.

Turning Enhance On: The ENHANCE section provides buttons to activate various image enhancement features:

STRUCTURE ENHANCE: This function reduces speckle noise while highlighting the boundaries of structures, making them clearer. The processing level can be adjusted using the [+] or [-] keys for Adjust key 1.
ECHO ENHANCE: This feature increases the overall contrast of the image and reduces noise, leading to a sharper and more defined ultrasound display.
BRIGHTNESS ENHANCE: This function increases contrast while maintaining the overall brightness level of the entire image, ensuring that details are visible without making the image too dark or too bright.

Switching to THE Mode (THE-P / THE-R): THE mode utilizes the harmonic components of the ultrasound signal reflected from tissue for imaging. This technique can improve image quality by reducing artifacts. The mode selector buttons allow users to switch between:

THE-P: This mode prioritizes penetration depth, making it suitable for visualizing deeper structures.
THE-R: This mode prioritizes resolution, offering finer detail for superficial structures.

Adjusting the Display Range: The depth/range of the ultrasound image can be adjusted using the [+] or [*] keys. The [→] key makes the depth/range smaller, while the [*] key makes it larger.

Adjustable Depth/Range: The available depth/range varies depending on the connected product.
- Ultrasound Probe: 2, 3, 4, 6, 9 & 12cm
- Ultrasound Endoscope: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 & 12cm

Turning the s-FOCUS On: s-FOCUS is an advanced function that reduces the change in resolution with distance from the ultrasound transducer surface (focus-dependent). It achieves this by combining received signals obtained from multiple transmissions through aperture synthesis processing.

Usage: This function cannot be turned on or off while an ultrasound image is frozen.
Visual Indicator: When s-FOCUS is active, the focus mark (leftward triangle) on the monitor display changes to a focus area mark (downward triangle above the ultrasound image and upward triangle below it).
Limitation: Cannot be performed in CHE mode.

Adjusting the Focus Number: The focus can be adjusted on the FOCUS MENU screen, accessible by pressing the FOCUS button on the B ADJUST tab.

AUTO Mode: Pressing the AUTO button automatically sets the focal position, PRESENT FOCUS, FOCUS NUM, and FOCUS LOCATION.
MANUAL Mode: Pressing the MANUAL button allows users to select the focal position using F1 to F12 buttons. Up to two focal points can be selected.

Adjusting the LE Reduction: This function suppresses low-level signals in received signals and adjusts the processing level to reduce noise. The processing level can be adjusted using the [+] or [-] keys for LE REDUCTION.

Adjusting the STC (Swept Gain Control): The STC allows users to adjust the brightness for specific distances using the brightness adjustment buttons ([+] and [-]). This helps compensate for signal attenuation at different depths. The STC can also be adjusted by tapping the brightness adjustment bar.

Measurement and Review

Using CINE REVIEW: This feature allows users to review previously acquired ultrasound images.

Process: Freeze the ultrasound image and press the CINE REVIEW key to switch to the image display.
Navigation:
- Swiping or pressing to the right displays newer images (frame numbers increase).
- Swiping or pressing to the left displays older images (frame numbers decrease).
Method: Image selection can be done via key operation or trackpad.

Distance Measurement: The device facilitates accurate distance measurements on the ultrasound image.

Process:
1. Press the MEASURE key to display the measurement screen on the touch panel.
2. A measurement mark (starting point) appears in the center of the ultrasound image.
3. Swipe the trackpad to move the measurement mark to the desired starting point.
4. Press the SET key or tap the trackpad to confirm the starting point. A second measurement mark (ending point) appears near the starting point.
Visuals: The measurement display area shows the measured distance (e.g., D1: 30.0mm), along with a measurement mark for the starting point, a measurement line, and a measurement mark for the ending point.

User Interaction and Customization

Enter Comments: Users can add comments to the ultrasound images.

Process:
1. Press the COMMENT key to switch the touch panel to the comment input screen, where a cursor mark appears.
2. Swipe the trackpad to move the cursor to the desired location for the comment.
3. Use the keyboard buttons on the touch panel to enter the comment.
4. Pressing the COMMENT key again confirms the comment.
Registered Comments: Registered comment buttons appear in the upper section of the comment input screen. Pressing a registered comment button displays the pre-saved comment on the monitor.
