Ultrasound System



Contents start

The EU-ME2 is a high-quality compact ultrasound processor for use with OLYMPUS endoscopic and endobronchial ultrasound (EUS and EBUS) equipment that has been designed for integration with conventional endoscopy on a single workstation. With its high resolution and an image display that promotes clear visualization, the EU-ME2 brings real clarity to your EUS and EBUS procedures, supporting better detection and characterization of lesions. A variety of new features such as the Elastography mode will explore the future of endosonography.

B-mode image quality has been substantially improved, making it possible to support more efficient localization of tumors and more accurate identification of tissue properties and boundaries. Clearer image delineation helps enable more precise direction for puncturing and aspiration during EUS-FNA and may make it easier to develop effective therapeutic practices.

Tissue Harmonic Echo (THE) mode

When ultrasound waves are propagated through tissue, distortion occurs and harmonic components are generated. The THE mode uses these components to build an image of the targeted area. Potential advantages of harmonic imaging include improved resolution, improved signal-to-noise ratio, and reduced artifacts.

Elastography (ELST) mode

An advanced form of ultrasound, elastography displays the relative stiffness of tissues by taking advantage of the deformation caused by the compression or vibrations generated by the heartbeat or vascular pulsations.

Pulse Wave Doppler (PW) mode

Pulse Wave Doppler measures blood flow velocities at specific locations, while cross-sectional images are viewed to spot the target vessel.

H-FLOW (High resolution Flow) mode

Especially useful for imaging small vessels around the tip of the endoscope, the H-FLOW mode can help facilitate more precise maneuvering during EUS-FNA/EBUS-TBNA by making it potentially less difficult to avoid vessels.

Contrast Harmonic EUS (CH-EUS) mode

Using technology designed to depict harmonics, the CH-EUS mode is expected to help realize enhanced sensitivity to tumors and other abnormal growths.
* Regulations and usage of ultrasound contrast agents vary according to the country where they are used and the type of agents. Please use the ultrasound contrast medium according to the instructions attached to the products.

Fully compatible with a wide range of EUS and EBUS scopes and probes

Integrating both electronic and mechanical scanning technologies, the EU-ME2 is a total endosonography solution compatible with virtually all available OLYMPUS ultrasound endoscopes and miniature probes, providing access to a full range of endosonographic applications.

Single monitor and single keyboard

The EU-ME2 features a user-friendly keyboard with a touch panel and trackball. The picture-in-picture function is standard, and when available, both endoscopic and ultrasound images can be displayed on a single monitor.

EVIS-ready and space-saving design

The EU-ME2 is designed to save space in your endoscopy suite. As an integral part of the OLYMPUS EVIS endoscopy system, it fits snugly on the standard endoscopy trolley, leaving plenty of room for all the other equipment you need.

Full support for endobronchial ultrasonography

The EU-ME2 is designed to support a wide range of EBUS procedures, such as EBUS guide-sheath guided transbronchial biopsy. By placing the guide sheath near the target lesion, which has been delineated by the miniature probe, you can easily perform brush cytology. Advancing the sampling device through the sheath after the miniature probe has been withdrawn helps improve accuracy and shorten examination time.
