Main voltage connection 5

The equipment has been set to 400 V, 2-phase, in the factory (see test certificate).

Adjustment to the line frequency is not needed. If the mains voltage is not 400 V, 2-phase at the installation site, a reconnection of the mains is necessary.

Should a reconnection for the mains voltage be necessary, this must be done at transformer T10 as well as p.c. board D711 (insertion or removal of fuses and labeling is specified in the wiring diagram, see Line Input page 5-3).

Change the rated voltage labels to the correct voltage (there are two labels on the generator and one on the stand). Labels are included in the installation material.

NOTE

For more details about changing mains, insertion or removal of jumpers, fuses, labeling etc., see Wiring Diagram.

For Sterling, the correction table for Kodak Min-R 2000 is recommended. The indications of this table are meant as recommendations. In case of failure the calibra-

tion of AEC with other series of correction tables may be attempted.

NOTE

If the film/screen combination in question is not listed in Table 1, the correction tables for one of the listed combinations will have to be used, although the tolerances for OD variation then cannot be guaranteed. Primarily, use the correction tables for Kodak Min-R 2000 if the film/screen in question is a Kodak etc.

11 - 6 Calibrating and adjusting the AEC

Configuration of the AEC 11

Definitions 11

Object table group 11

An object table group contains all object tables of the same type. There are four groups of object tables - Grid, No grid, Magnification and Stereo. For example the object table group Grid, consists of Grid 18x24 and Grid 24x30.

General conditions 11

When performing the settings in this chapter, there are some general conditions valid for all settings:

• The detector is to be in chestwall position.

MAM00616

• The AEC calibration plexi must extend at least 10 mm beyond the chestwall edge of the

table and be centered, see Fig. 2, Page 11 - 8. Place the AEC calibration plexi in the same position for all exposures.

Calibration conditions 11

Compression plate must not be used during the calibration of correction tables. From the point sensitivity correction (fine setting) and further on, a compression plate may be used.

Reference cassette 11

Every MAMMOMAT should have a reference cassette. Use this reference cassette where required and for the settings in this chapter. If there is no dedicated reference cassette, pick one cassette, mark it and use it for the settings in this chapter.

Film 11

When calibrating the wings and the correction tables, it is possible to use the same film for each exposure. However, when setting the sensitivity, the operator needs to check the optical density and the film must be exchanged and developed between every exposure.

Mains voltage 11

Unless otherwise stated, the mains voltage and system must be ON and the service PC program running, before performing any setting in this chapter.

Sensitivity conditions 11

• One step (1/8 E.P.) corresponds to approximately 0.06 O.D. with an incremental gamma

of 5.

• Measure the optical density on the emulsion side of the film.

Calibrating and adjusting the AEC 11 - 7

Correction of the measured Optical Density (O.D.) 11

Due to variations in the developing conditions (see also section "Normal developing conditions") the measured optical density of one specific image might not correspond to the adjusted optical density (sensitivity setting). Therefore the optical density has to be corrected for the variations in the developing conditions.

NOTE

This correction has to be made for

1. fine setting of sensitivity correction

2. setting of sensitivity

3. final testing.

Procedure 11

• - For grid/no grid: cover the area far from the chestwall side with metal plate (part no.

65 52 728).

- For magnification: place metal plate (part no. 65 61 026) inside the magnification table as close as possible to the cassette to prevent scattered radiation and cover the area far from the chestwall side.

• Develop all films with a sensitometer strip on the part that was covered by the metal plate

(part no. 65 52 728 or 65 61 062).

• Measure the optical density in two places: OD

(as described in Fig. 2) and OD

strip

(on

the sensitometer strip).

• Calculate the corrected O.D. as follows:

= ODm + (OD

corr

strip_ref

- OD

strip

)

Normal developing conditions 11

When measuring the O.D., it is essential that the working conditions are as close to normal as possible. There are several parameters that may effect the results:

• Temperature of developer and dryer

• Feeding and developing speed

• Replenishing speed of developer and fixer (liquids)

If possible, develop the film among other films when the developer is warm and stabilized.

AEC Correction tables 11

This section will guide you through the following steps:

• Installation of correction tables (F2).

• Calibration of correction tables (F3), including rough setting of sensitivity correction.

The AEC uses one correction table for each Anode/Filter/Speed combination. Each correction table has separate corrections for each object table group (Magnification, Grid, No grid and Stereo).

NOTICE

For exact positioning of the needle, the anode/filter combination "Mo/Mo" or "Mo/Rh" must be used. Therefore, calibration does not have to be attempted for W/Rh combination in stereo mode.

12 - 2 Dose Calculation System

Configuring of Dose Calculation System 12

The Dose Calculation System comes with factory default values. Normally, the factory default values should be used. If desired, measurements of HVL (Half Value Layer) and Dose Exchange factors can be performed to improve the accuracy of displayed dose value. These measurements should be performed by the hospital’s medical physicist, and are described in the document "Radiographic Handbook, Dose Calculation System, SPB7-230.206.01...". The measuring procedure is quite complicated, and should only be performed by a physicist familiar to similar measurements. If the HVL and Dose Exchange values are to be measured, the document "Service Program" describes how to enter the values in the Dose Calculation Program.

If reinstalling factory default parameters, all previously entered measured data (HVL values and Dose exchange factors) will be lost. However, the measured data should already be noted in the document "Radiographic Handbook".

Label 12

If the Dose Calculation System is enabled, affix a mAs / mGy label over the "mAs" text on the control and display panel. The label is found in register 3 of the Technical Manual binder.
