FG table and GA table 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 will be required for calculating GA. If the preset formula does not have corresponding GA table, the system will not display GA. If the user has entered LMP or BBT, FG table will then be required for calculating GA. If the preset formula does not have corresponding FG table, the system will not display GA. After the user has entered LMP or BBT, the system will calculate GA based on FG table for all obstetric measured items. And at the same time the result window and the obstetric report will be refreshed. (2) 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.

1.5.2 Measurement application preset The [Meas App] preset page is shown in the figure below.

1-8

Preset

„

Auto average (only available for obstetric measurements) It is used to preset if the measure items are to be calculated with the average values. √: Calculate the average of the recent measurement values (up to three) . (Note: the calculation item can’t calculate the average, use the measure average to calculate.) X: the average calculation isn’t conducted, and the latest measure value is the measurement result.

„

Formulae It is used to preset the formulae for calculating the uteras volume, ovary volume, thyroid volume, prostate volume, and residual urine volume. You can either use the default factors in the formulae or modify them. To modify a factor, move the cursor to the box where the factor to be modified locates, press the 『Set』 key, and then edit the factor.

1.6 Post Process Preset The post process preset is used to set parameters and curves for post process. The items can be preset include gray transformation curve, gray rejection curve and 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. Move the cursor to the [B Post Proc] item in the Preset menu and press the 『Set』 key. Then the B Post Process Preset dialog box pops up. See the following figure.

1-9

Preset

The B Post Process Preset dialog box has eight pages representing eight kinds of gray map. The preset items and preset method in these eight 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 There are nine “y” adjusting points on the gray transformation curve used to adjust the shape of the curve. To adjust the gray transformation 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, and 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, and 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 into the current page of the dialog box.

4

Press the 『Set』 key on the [Linear] button, the gray transformation curve will return to the factory default shape.

5

Press the 『Set』 key on the [OK] button to save the modification or on the [Cancel] button 1-10
