Page 3: Introduction
1. Introduction This document ("MicrUs and MicrUs Pro Series Ultrasound Systems Echo Wave A Software User Manual") describes the TELEMED Ultrasound Systems based on MicrUs or MicrUs Pro series of ultrasound scanners and "Echo Wave A" ultrasound scanning software. This document describes the "Echo Wave A" ultrasound software user interface, its structure, controls and how to use this software for ultrasound processing. -
Page 4: System Startup And Shutdown
2. System Startup and Shutdown 2.1. System Startup If the system was properly installed and connected, perform the following actions to start the system: 1. If required, power up mobile phone or tablet computer and unlock the screen. 2. Click “Echo Wave A” icon. The icon may be not on first, but on second or other page (or on one of the pages of installed applications), so you may need to sweep through pages to find it. -
Page 5: Software User Interface Structure
3. Software User Interface Structure 3.1. Main Window Description Scan direction marker that indicates at what side is first probe element. Remaining phone battery indicator. Zero depth (probe surface) tick mark. Depth scale line. TGC (Time Gain Compensation) curve. TELEMED ... -
Page 6: Types Of Controls
Focusing depth marker. Actual scanning depth (numerical value in millimeters). Buttons to record cine, save image, freeze/run, open settings (presets, options), measure distance, measure area (using ellipse), delete measurements. Ultrasound scanning controls (Gain, Power, Depth and others). This area can be scrolled up/down. -
Page 7: Typical Ultrasound Examination Workflow
4. Typical Ultrasound Examination Workflow To perform ultrasound examination, start software and follow these steps: 1. Click Freeze/Run button to freeze/run ultrasound scanning and clear all measurements. 2. If required, enter patient identifier (ID). To do this, click “Settings” button , then “Patient”... -
Page 8: Using Ultrasound Scanning Presets
5. Using Ultrasound Scanning Presets In order to apply ultrasound scanning preset, unfreeze ultrasound scanning (if now it is frozen) by clicking “Freeze/Run” button and perform the following actions: 1. Open the presets list by clicking on the "Settings" button , then “Presets”... - Page 9 To save current ultrasound scanning parameters as preset for future use, please perform the following actions: 1. Open the presets list by clicking on the "Settings" button and “Presets” tab. 2. Click text field at the right of “Preset Name:” text, enter preset name using on-screen keyboard and click “Save Preset”...

Page 10: Patient Information
6. Patient Information To enter patient identifier, please perform the following actions: 1. Open the Settings window by clicking on the "Settings" button , then click “Patient” button at the top. 2. Click textbox after “Patient ID”. 3. Enter patient identifier. 4. -
Page 11: Adjusting Ultrasound Image Quality
7. Adjusting Ultrasound Image Quality To adjust desired scanning parameter, click corresponding button at the bottom of software window and do sweeps on ultrasound image (depending on control type). Control types were described in section “Types of Controls” of this document. All scanning parameters will be described in next sections. If any parameter is controlled using other method, then this information will be presented in the section that describes this parameter. -
Page 12: Dynamic Range
Values The list of available depth values depends on the type of probe used. Measurement units used - millimeters (mm). The painted depth scale on the ultrasound image displays tick marks at 10 mm intervals. Adjustment Click “Depth” button and do sweeps on ultrasound image. Relations to other controls After adjusting the Depth you may need to adjust the Gain, TGC (Time Gain Compensation) and the Focus controls. -
Page 13: Gain
Relations to other controls After adjusting the Power level you may need to adjust the Gain. If you decrease the power level you may need to increase the gain. If you increase the power level you may need to decrease the gain. Hints Always optimize gain before increasing power levels. -
Page 14: Frequency
Caution When scanning, please observe the scan direction marker that is painted on the ultrasound image in order to avoid any possible confusion. 7.1.7. Frequency Description Frequency is a characteristic that defines the resolution of ultrasonic signal. Higher frequencies increase resolution of the incoming ultrasonic signal but reduce the visibility of examined tissues at greater depths. -
Page 15: Image Enhancement
Values The range of values usually available is 0-32. The value means at what level the gray scale values are rejected. A value of 0 means that no rejection is performed. Higher values mean that more data is rejected. Adjustment Click “Rejection”... -
Page 16: Lines Density
7.1.12. Lines Density Description Lines density adjusts the number of ultrasonic beams that are used for scanning ultrasound image. Use a higher density when you are viewing small objects. A lower density allows you to increase the frame rate and can be used when viewing fast moving objects (for example the heart). Adjustment Click “Lines Density”... -
Page 17: Negative
7.1.15. Negative Description In order to invert the palette of the ultrasound image (change the dark gray scale values to light and vice versa) you can use the Negative control. Adjustment Click “Negative” button. 7.1.16. Zoom To perform zoom in or zoom out of the B mode ultrasound image, click “Zoom” button and do sweeps on ultrasound image. -
Page 18: Tgc (Time Gain Compensation)
7.1.17. TGC (Time Gain Compensation) The Time Gain Compensation (TGC) controls adjust how returning signals are amplified in order to correct the attenuation that varies depending on the scanning depth and the tissue being observed. Using the TGC controls you can equalize amplification of the returning echo signal so that the density of echoes at different depths is similar. -
Page 19: Measurements And Calculations
8. Measurements and Calculations This section describes the user interface for measurements and calculations. For equations and references please see the "Echo Wave A Software Reference Manual". 8.1. B Mode Measurements In order to perform B mode measurements, scan ultrasound image, freeze ultrasound by clicking “Freeze/Run”... -
Page 20: Deleting Performed Measurements
Measurement object (ellipse) and result: At first endpoint is displayed measurement number (“1:”) and measurement result: “17.26 cm2” area, “P=154.5 mm” circumference and “V=43.236 cm3” volume. Please note that for ellipse long axis (first axis) are marked two endpoint markers, while for short axis (second axis) is marked only one endpoint. -
Page 21: Saving And Loading Images And Cines
9. Saving and Loading Images and Cines To save ultrasound image, click “Save Image” button . Images (in JPG format) are saved to "Internal Storage>Pictures". To record cine, unfreeze ultrasound, click “Record” button . To stop recording, click “Stop” button . -
