Safety Precautions

Important Product Safety Instructions

•Please read this manual before using the system, paying special attention to all WARNINGS and

CAUTIONS. Keep the manual and refer to it frequently.

•Do not install system near any heat sources, such as radiators, heat registers, stoves, or other apparatuses

that produce heat.

•Only use parts and accessories specified by the system manufacture, Echo Medical Systems or Active

Field Resources.

•Do not attempt to service the system yourself, opening or removing covers may expose you to

dangerous voltages and/or other hazards. Refer all servicing to qualified service personnel. Servicing is

required when the system has been damaged in any way or the system does not operate normally.

Important Safety Precautions

5-Gauss Fringe Field Extent

•Animal Systems – the 5-gauss fringe field extends in a 228.6-mm [9-in] radius from the center of

the antenna opening creating a hemisphere. An equal field is present on the opposite side of the

system.

•Infant/Human Style Systems – for information about the 5-gauss fringe field extents please see

the Site Planning Guides for these systems.

Required Training

Echo Medical Systems and Active Field Resources strongly recommends that ALL users complete a

course of training with one of our factory trained technicians or engineers before unsupervised operation

of the system. Training sessions are available on request for a nominal fee. For more information

please contact Echo Medical Systems or Active field Resources at 281-492-0082 x4 or

[email protected].

Getting Started

Echo Medical Systems’ EchoMRI™ Whole Body Composition Analyzers employ magnetic resonance

relaxation analysis for measuring live body composition in terms of Fat tissue, Lean tissue, Free Water and

Total Water.

Most of the graphical user interface of EchoMRI™ operating software is concentrated in one window,

optimized for simplicity and convenience of use. This manual will elaborate on the software and illustrate its

operation.

Power up:

(1) Turn on the computer (2a in Figure 2.1) and allow Windows™ to boot fully.

(2) Turn on the electronics module (2b in Figure 2.1).

Figure 2.1: Powering up of the PC and the electronics

Starting the EchoMRI™ software:

Double-click shortcut on the Windows™ desktop to start the program.

Manual

To view this manual, press tool-strip button "Help →Manual".

Managing the File System

At the start of EchoMRI™ software the default output folder (used for storage of measured data) is presented

(3a in Figure 3.1). We recommend to avoid using the default output folder and create other folders at locations

convenient for you (see also suggestions on directory tree below).

To select another existing or to create a new output folder, click “Output Folder →Browse / New” (3b in

Figure 3.1). A dialog pops up with a directory tree in the lower, larger window and a line to type in a path in the

upper, smaller window. Either of the upper and lower windows can be used to select destination folder (3c in

Figure 3.2).

One method to create a new output folder is to select an existing parent folder from the tree in the lower

window and then type a backslash character (\) followed by a new folder name into the upper window of the

dialog.

Another method is to modify the name of an existing folder in the upper window and then a new folder will be

created on the same tree level as the one from which you started.

After you press OK the dialog will ask for confirmation that the new folder should indeed be created.

Note that even though a new folder can be created in this way anywhere accessible, the software will refuse to

scan in a folder which is a sub- folder of any folder in which scans have been previously performed.

Figure 3.1

Figure 3.2

We recommend that users create a folder/directory structure suited for their data organization needs. A simple

option is to have directory tree suited for the needs of your departments, research teams and test subjects. An

example of such a directory system is shown in Figure 3.3.

Figure 3.3

Page 7 of 20 2/3/2010 @ 9:00 AM

We also recommend to moderate the size of data accumulated in any folder. If it exceeds some limit the

software would offer a warning every time a scan is started (this limit can be altered by a person authorized to

use EMSService or by Echo Medical Systems, remotely or via email).

Probe Selection (employed on multi-probe models)

Some devices, such as EchoMRI-3-in-1™, EchoMRI-4-in-1™, Rat-and-Mouse, Rat-and-Piglet, etc, have two

or more probes of different sizes and designations, e.g. in 3-in-1 there is “Mice” (for whole mouse-size

animals), “Tissue”, and “Biopsy”. Use Probe Selection combo box (3d in Figure 3.1) to select the desired probe.

The probe selector is not employed on devices with only a single type of probe.

Primary Accumulation Number

The random errors in Fat and Lean measurements can be reduced by increasing the number of Primary

Accumulations, resulting in longer scan duration. The user can select this number in the Primary Accumulation

combo box (3e in Figure 3.1). Every time the EchoMRI software is started the number of accumulations is set

to a default value we recommend for most common use.

Water Stage

If not interested in free water and total water, the user can turn off the Water Stage (3f in Figure 3.1) and so

reduce scan duration by about 40 seconds.

Controlling the Magnet (only on devices with electric magnets)

The electric magnet is controlled by a separate power supply and it is monitored by the software. The magnet

indicator button (3g in Figure 3.2) displays the current status of the magnet. Once the magnet is turned on, the

user may proceed to System Test or Scan.

System Test - Alt + S Key

A System Test is recommended once a day prior to measurement scans, and it is performed by clicking the

System Test button (4a in Figure 4.1) or pressing "Alt + S". Before the System Test is executed by the

computer, a reminder is displayed for the operator to verify that the correct test sample is placed in the device.

The system is delivered with a test sample (for each probe) which serves as a standard of fat mass in the System

Test.

After you confirm by pressing button "Yes", the progress of the scan is displayed in the Scan Stages Report

window (4b in Figure 4.1).

If the System Test results fall outside of the expected ranges, a warning message will be displayed (4c in Figure

4.2). The warning message suggests to check whether the correct test sample has been used and to repeat the

System Test with the correct sample. If the problem persists, please report it to Echo Medical Systems.

Pre-Scan Label -F2 Key (supplementary data input)

To enter supplementary data and comments on scan subjects prior to the scan, either press button "Pre-Scan

Label" (5a in Figure 5.1), or press the F2 key on the keyboard. A dialog box will open (5b in Figure 5.1) to

allow the input.

NOTE: This is the only way to label and place weight with the scan. After scan is complete one cannot edit

label and weight values.

Label and the contents of other columns (except Comments) must be entered in a single line, each.

Comments can occupy more than one line at the time of input, however in the eventual records all of the lines of

Comments will be collected into a single string.

When you complete the entry, click OK to save it and close the dialog. Pressing Cancel will cause the dialog to

discard all entries and close.

Immediately after the dialog is closed with OK, the entered supplementary data appears in a compact form in

the Scan Stages Report window.

After the scan is completed, the supplementary data appears in the Measured Results List (5c of Figure 5.2).

The supplementary data does not persist for subsequent scans unless Repeat Scans was used.

Figure 5.2

Start Scan - F5 key

A measurement scan starts when the Start Scan button is clicked (5d of Figure 5.2) or, alternatively, the

keyboard button F5 is pressed.

In some devices, before the scan starts, the position of the holder is checked, and if the holder is not fully

inserted a warning message suggests to insert it to the end.

Various stages of the scan such as Tuning, Recovery after Tuning, Primary Stage, Water Stage, and Scan Done

are displayed in the Scan Stages Report (5e in Figure 5.2).

After the scan is completed, the results are displayed in the Measured Results List (5c in Figure 5.2).

Progress of the scan is also indicated by the progress bar.

Stop Scan - F6 key

In some situations (e.g. the operator forgot to input some important details or did not place the correct subject in

the holder, etc) the operator may want to abort a scan. The STOP button (5f in Figure 5.2) or the keyboard
