3. Safety Precautions Please observe the following precautions to ensure patient and operator safety when using this system.

CAUTION: 1. Display the most suitable image and select the most suitable measurement mode for the intended measurement. The results must be determined by a specialist. 2. The basic measurement results are not displayed in the exam report. 3. Be sure to perform measurement within images. If the area is outside the image, incorrect diagnosis may result. 4. The detailed precautions for each measurement are described in the

corresponding

section.

Read

and

understand

these

precautions before performing the measurement. 5. Data in temporary storage areas, such as the CINE memory, is deleted when the power supply is turned OFF or when the Patient switch is pressed. Such data may also occasionally be deleted due to accidents. To minimize the possibility of reexamination being required as a result of unintended data deletion, back up the required images on external storage media. 6. Refer to the Operator’s Manual (Basic Volume) for precautions regarding the use of this system.

Preset

Preset function is used to set the system operating environment, status and the configuration parameters for each exam mode. The preset values are saved in the memory inside the system, which will not be lost if power-off occurs so as to ensure that the system operates in the user-desired status automatically after each start-up. This chapter gives detailed description about how to make system configuration through using the preset menu in Preset mode.

1.1 Access/Exit Preset Mode Access the preset mode: Press the 『File』 key on the control panel. The 『File』 lamp lights up. The FILE MENU appears on the right part of the screen. See figure below. Then select the preset item and press 『Set』 key. The system accesses the preset mode. Select the item in the PRESET menu to preset the corresponding parameters.

If a dialog box having more than one page, first move the cursor to select the button of

the desired page so as to open the corresponding preset page. 3.

Move the cursor to the bar of the parameter to be adjusted and use the 『Set』 or the

『Back』 key to adjust the parameter. At this time, the operating information is displayed in the Help bar. 4.

After setting the information in the current page, select the button of another page to set

other parameters. After all the parameters have been set up, press the 『Set』 key on the 「Ok」 button to make these settings come into effect and be saved in the system, and at the same time to close the dialog box. 5.

To cancel the modifications, just press the 『Set』 key on the 「Cancel」 button. This

action at the same time closes the dialog box. 6.

Move the cursor to the [Return] item of the PRESET menu and press the 『Set』 key to

close the PRESET menu.

There are also some special buttons in the preset dialog box, whose functions are: z

「Record Current」

Besides setting the parameters in the current page one by one, the user can also use the “record the current value” method to preset parameters. Press the 『Set』 key on the 「Record Current」 to set each parameter (curve) as the value (parameter or curve) used by the system before accessing the preset mode. That is to say to set up the current operating parameters of the system as the preset parameters. NOTE:「Record Current」 buttons are only valid in the current page.

1.3 General preset Move the cursor to select the [General] item in the menu to call up the [General Preset] dialog box. See the following figure.

1.4 Preset Parameters of Exam Mode The system has five exam modes, which are abdomen (general), gynecology, cardiac, obstetric and small parts. Each exam mode has preset the most suitable operating environment. The preset contents of different exam modes are similar. Now use the obstetric exam as an example to illustrate how to preset the operating environment. The preset dialog box of the obstetric exam has three pages, which are “Parameter”,”B IP” and “M IP”. Parameter preset 1.

Select the [Obstetric] item in the PRESET menu, the dialog box of “Obstetric Preset” pops up. The default is that Parameter page is opened. The dialog box is as shown in the following figure. The preset items are shown in table 1-2.

2.

Move the cursor onto the adjustment button for the parameter item to be modified, and press the 『Set』or『Back』key to modify the parameters. At this time the prompt information is displayed in the help information bar.

NOTE: FG and GA are used in these formulae. In formula preset, three situations are presented for each item. Some formulae are included in both FG and GA tables but others are exclusive for GA or FG table. Please select reasonable formula according to below information: 1.

In the process of obstetric measurement, if the user does not enter LMP or BBT, GA table

of formula will be required for calculating GA. If the formula have not GA table, the system will not display GA. 2.

If the user has entered LMP or BBT, FG table will then be required for calculating GA.

And the system will calculate GA based on FG table for all obstetric measured items. And at the same time the result window and report will be refreshed. If the formula have not FG table, the system will not display GA. 3.

Data of growth curve are all sourced from FG table. The user could select the formula in

the pull-down list. The system will accordingly display the growth curve corresponding to the formula. The initial curve being displayed is decided by the preset formula. If the formula does not have corresponding FG table, fetal growth curve will not be displayed.

1.6 Preset Post Process Curve and Parameter The post process preset is used to set parameters and curves for post process. Preset items: gray transformation curve, gray rejection curve, γ correction. The post process preset of B-mode and M-mode is realized via two dialog boxes. The preset procedures for the two modes are basically the same. Now we use B-mode post process preset as an example to illustrate the procedures.

1-11

Preset

Select the [B Post Proc] item in the PRESET menu. The B Post Process Preset dialog box pops up. See the following figure.

The B Post Process Preset dialog box has five pages representing 5 kinds of gray map. The preset items and preset method in these five pages are the same. Now use the Map1 page as an example. Note: The post process curves and parameters practically used by the system are set in the “Parameter” page of the preset dialog box of exam mode.

1.6.1 Gray Transformation Curve Method: There are nine “y” adjusting points on the gray transformation curve used to adjust the shape of the curve. 1.

Press 『Set』 key on the “Map1” page button of the B Post Process Preset dialog box

to select the “standard” gray map. 2.

Move the cursor to an adjusting point on the curve, the cursor changes into a “

”.

Press the 『Set』 key and roll the trackball to move the “y” so as to adjust the curve. After adjusting the curve, press the 『Set』 key again to finish the adjustment. Or press the 『Back』 key to cancel the operation, the “y” point will return to the original position. The system updates the “Result” curve. Use the same method to adjust other points. 3.

Another way to set the gray transformation curve is adjusted by using the 「Record

Current」 button. Actually, this method is a more practical one. Press the 『Set』 key on the 「 Record Current 」 to set the curve as the one currently used by the system and simultaneously to load the gray rejection curve and γ correction currently used by the system 1-12
