Important notes on start-up 1

The MAMMOMAT is adjusted, programmed and tested in the factory, leaving only the adaption to the on-site mains voltage and the functi onal tests to be performed.

When the measurements to be made (kV, mAs, etc.) are within th e tolerances stated in these instructions, this confirms that the settings made in the factory have not changed and the equipment is fully serviceable.

The measured values marked with entered in the "start-up" column in the test certificate provided.

The service PC is required only for programming according to:

? in Chapter 10 "Checks with high voltage" shall be

• Chapter 10 "Checks with high voltage"

• Chapter 11 "Start-up and functional test of the IONTOMAT"

Programming the "Correction curve" Setting the "sensitivity" (film density) Setting the "sensitivity correction" (adaption to different exposure techniques)

• Chapter 12 "Further programming"

• Chapter 18 "Final procedures"

Description of the Service-PC syntax is found in Chapter 20 "Appen dix".

If the generator is switched off with the Service PC connected, wait approximately 5 s before switching it on again.

Checking and recording for the area of application of the X-ray

decree (§16 Germany)

In the area of application of the X-ray decree, an acceptance test certificate is supplied, with most of the data filled in by the factory.

Only:

• the cut-off dose

• the resolution of the film/screen systems used

• the output values of the constancy test

must be determined by the owner of the equipment and recorded in the acceptance test certificate. Furthermor e, the front page of the acceptance test certificate must also be

completed with the operator´s data.

Prerequisites 1 - 5

Checking and recording for the DHHS area of application 1

In the area of application of the DHHS regulations, maintenance measurements must be made according to the "DHHS Maintenance Instructio ns" SPB7-230.662.03.01.02 and the "DHHS Supplements to the instructions for use" SPB7-230.661.02.01.02.

Sections 1

• Required labels.

• Radiation ON indicators.

• Manual termination of exposure.

• Checking the maximum adjustable mAs.

• Filters in beam limiting device (BLD).

• Reproducibility.

• kVp-accuracy.

• mAs-accuracy.

• Automatic exposure control (AEC).

• Coincidence of radiation field/image receptor.

• Alignment of light field/X-ray field.

• Illuminance of light localizer (light field).

• Shut-down of motor-driven compression movement.

The result must be recorded in "DHHS Measurement certificates" SPB7-230.663.03.01.02. Some of the values to be determined can be taken from the acceptance test certificate. The radiation-field limitat ion is set at the factor y and recorded i n the acceptance t est certi f-

icate. If the measurements to be made concerning the radiation-fi eld li mitati on are withi n the tol-

erances stated in these instructions, this confirms that the settings made at the factory have not changed.

Note on delivery state 1

It is very important that any interventi on in the equipment will start with disconnecting it from the power supply with the main circuit-breaker. Before removing or inse rting any of the printed circuit board, swit ch of the equipment. To prevent accidental triggering of high voltage and radiation, set the switch S2 (SS) on p.c. board D702 to "OFF" (lower posit ion, no triggering of the SS relay).

If the system is only switched off at the control panel or with S2/D711, line voltage will still be present at the generator line connection, line filter Z1, Z2, transformer T1, transformer T10 and p.c. board D711 (see wiring diagram).

After shut-down of the system, there may still be 380 V DC present on the intermediate circuit. This will be indicated by LED V24 on p.c. board D710. The voltage will drop to less than 30 V within about 3 minutes, the LED goes out at about 30 V.

2 - 1

The p.c. boards contain electrostatic highly sensitive components requiring particular care in their handling (ground before making contact and place only on a conductive surface).

The edges of the metal curtain of the stand are very sharp and may cause severe injury. Apply the protective strips as mentioned in section Protective Measures after removing the covers fr om th the stand. Remove the protective strips only when the covers are to be mounted or when vertical adjustment of the swivel-arm system is necessary.

Other film/screen combinations 11

In case the customer uses another film/screen combination t han those the correction curves are optimized for, see table 1 of correction curves on page 11 - 1, proceed as follows:

1. Begin with curve C, speed H, and make test exposures usi ng a grid table at 25 kV (Mo/Mo), 2 and 6 cm plexi (5 cm if limit (ER550) or ER 013 occurs, due to insufficient dose rat e). If the image from 6 cm plexi (O.D.-6 cm) is lighter than one from 2 cm plexi (O.D.-2 cm), choose correction curve A or B (A makes images from thick objects darker than B does, i .e. A corrects more than B). On the other hand, if O.D.-6 cm is darker than O.D.-2 cm, choose curve D. Repeat the test with the chosen curve. The difference betwee n O.D.-6 cm and O.D.-2 cm ( should be less than 0.30 O.D.

2. Now test 27 kV, 2 and 6 cm. Try even 30 and 35 kV if these kV´s are of interest for

the customer. If this another curve (choose between A, B, C and D) at 27 kV. Choose the best one and repeat the test at 25 kV. Continue in this manner until the res ult is as good as possible for the kV´s of interest for the customer. Diagrams 1, 3, 5 and 7 on the following pages can be of help. Note th at the steeper the curve is, the more the thicker objects are corrected (t hey will be darker).

∆ Ο.D.

is ≤ 0.30 O.D., go to 3. If not, it is necessar y to test

∆ Ο.D.)

3. Check also the correction with 2 cm plexi between the diffe rent kV values of interest. If this not be possible to reach the specified O. D. corrections, choose then the best compromise for the customer´s needs.

4. Do the same tests with magnification table, but use 2 and 5 cm plexi instead. The permissible satisfactory, try another curve wit h speed button D. Choose between correction curves A, B, C and D. Diagrams 2, 4, 6, and 8 on the foll owing pages can be of help. Normally, the magnification tables and the conta ct exposures tables function properly with the same curve family, which means t hat the other speed button can be used for another film/screen combinat ion.

NOTICE

Checking the film density 11

The sensitivity to be programmed must be determined by means of test exposur es with anode/filter combination Mo/Mo at 25 kV, or kV preferred by the customer, and 20 mm plexiglass.

The plexi must extend at least 3 0 mm behind the rear ed ge of the det ector marking on t he compression plate and 10 mm beyond the chest wall edge of the table.

The detector shall be nearest the chest wall. When making test exposures, ensure correct positioning of the plexiglass plates.

Measuring point

40 mm

Minimum projecting Length: 10 mm

Detector nearest chest wall. Place the plexi plates in the same position for all exposures and measure the density as shown above on the emulsion side of the film.

Start with the sensitivity listed in table 1 and adjust a density of approx 1.5 ("Sensitivity H"). Repeat this procedure on the other "wing" (base plate) .

Change to the other film/screen combination, if used, and program "Sensitivity D" for the density as above. Repeat this procedure on the other "wing" (base plate).

The final values are dependent on the type of cassette used and desired opti cal density.

Checking the automatic transparency adaption 11

Check the automatic transparency adaption with a grid table wit h 20, 40 and 60 mm plexi at the voltage(s) preferred by the customer (within 25-35 kV) and all anode/filter combinations. If the dose rate is too low (error 013 or "Limit") , use 50 mm plexi instead of 60 mm.

Tolerance:

0.3 density difference at constant voltage and thickness 20-60 mm.

≤

0.3 at constant thickness and 25-35 kV.

≤

Tolerance valid for grid tables and film/screen combinat ion according to table 1.

These limits apply for film with max. gamma 4.0 measured at the density chosen.

The film density levels may vary from cassette to cassette. Therefore, be sure to use one and the same cassette for all test exposures.

When making test exposures, follow the instructi ons on page 11 - 8 for positioning the plexiglass plates and measuring the density.

Both "wings" must be checked, if the stand is equipped with pivoting object-table arm (Bucky selector).

Start with 60 mm plexi and compress. Make sure that the display indicates at least 60 mm. Make an exposure and measure the optical density. Repeat this procedure with 50 mm, 40 mm and 20 mm plexi.

Change density with the densit y setti ng buttons on t he control panel as needed ( the panel programming switch must be ON, see Service PC program Configuration, Miscella- neous, Panel programming). The optical density for the four different programs shall be as near as possible to 1.5 O.D. (or the density preferred by the customer). Store with the memory button.
