WHILE SERVICING, IN ORDER TO AVOID EITHER PERSONAL INJURY OR DAMAGE TO
THE UNIT.
CAUTION RADIATION SAFETY RULES
Some procedures described in this manual produces X-ray radiation. Always follow rules
for radiation safety.
Never touch or scratch the surface of the x-ray tube radiation window. The window is
made of beryllium that can be harmful if inhaled or swallowed.
Never attempt to open the TUBE-HEAD. It does not contain any serviceable parts and this
would make it inoperable and void the warranty.
Never make any exposures without the Mo/Al filter in the beam, or without the beam limit-
ing device (collimator) in place. Otherwise the radiation safety cannot be guaranteed.
CAUTION ELECTRICAL SAFETY RULES
The unit contains hazardous voltages. While servicing internal parts, always disconnect
the unit from the mains (if possible) by removing the plug from the wall outlet, and wait for
2 minutes before touching any electrical parts.
Always replace the fuses with ones of the same type and rating. Otherwise patient, opera-
tor or equipment safety cannot be guaranteed.
The circuit boards can be damaged due to static discharges and requires careful handling
and storage.
CAUTION GENERAL SAFETY RULES
The unit must be serviced only by qualified personnel, trained by PLANMED Repairs and
parts replaced by unqualified personnel carry no warranty.
Periodical maintenance as described in this manual must be performed on a regular basis,
to ensure the safety and image quality of the unit.
Some procedures described in the unit could jeopardize the function of the unit, if not fol-
lowed as stated.

MANUAL VERSIONS
Technical Manual
2 MANUAL VERSIONS
PLANMED pursues a policy of continuous product development. Although every effort is made to
produce up-to-date product documentation this manual should not be regarded as an infallible
guide to current production specifications. Planmed reserves the right to make changes to speci-
fications without prior notice. This manual is valid for all versions of the Sophie Mammogra-
phy X-ray units with SID 650mm. In case you have the unit with SID 600mm, you need a
technical manual revision 9.
3UNITMODELS
All Sophie Mammography X-ray unit models are electrically and mechanically identical, except
for some minor details. This manual is valid for all versions since the differences are small.
The darkroom versus daylight differs only in the size and dimensions of the cassette table and
film marking device.
The mobile versus the stationary units differs only in the base wheel system and the X-ray tube
locking system (for transportation).
Daylight units can be converted to darkroom units (and vice versa), please contact PLANMED for
details.
NOTE THIS TECHNICAL MANUAL IS VALID FOR SOFTWARE REVISIONS: TUBE CPU 2.41
(OR LATER) AND REAR CPU 4.41 (OR LATER).
If you find that your SOPHIE doesn’t have some keyboard functions, or its keyboard
functions differs from procedures described in this manual, then either the software
must be replaced with at least the above mentioned revision, or you have to relate to
an older version of this manual. The former procedure is recommended.

SOFTWARE REVISIONS & COMPATIBILITY
Technical Manual
4 SOFTWARE REVISIONS & COMPATIBILITY
Background
Since this unit is fully microprocessor controlled, its operation is controlled by the currently
installed software. PLANMED reserves the right to improve functionality or to add new features to
the product by modifying the software and/or hardware. Manuals are updated accordingly and
technical bulletins published in order to inform about these changes or additions.
Hardware compatibility
As a general rule; new software releases are compatible with all existing hardware. New software
releases (or possible upgrading kits containing new software) are normally directly compatible
with existing hardware, but not necessarily without some re-calibration procedures.
Software numbering & compatibility
Since the unit contains two communicating microprocessors, these must be able to “understand”
each other.
Incompatible software versions should never be used together, the unit would either be totally
non-functional, produce continuous error codes, or some important features or functions could be
missing. However, no damage or safety hazard would result if two non-compatible software chips
are accidentally used together.
The following table contains information about compatible software versions. Use versions
together only as listed in this table.

Technical Manual
7.2 Toshiba E7272 x-ray tube ratings
Manual exposures
With manual exposures the tube kV, mAs and focal spot can be selected by the user. The mA
value is automatically determined by the selected kV value, and the exposure time is determined
by the selected mAs value. The mA value used is always the highest possible value, that
depends on the kV value, focal spot, exposure time and line frequency (see following table on the
next page). The maximum exposure time is 6.0 sec. for the large focal spot, and 9.9 sec. for the
small focal spot. The minimum mAs value is 10 mAs and it can be increased in approx. 20%
steps to the maximum (see values below). The maximum mAs value for the large focal spot is
either 300, 500, 550 or 600 mAs, depending on the value of the service mode parameter 6. The
maximum mAs value for the small focal spot is 200 mAs.
The possible mAs values are: 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 50, 60, 70, 85, 100, 120, 140,
160, 180, 200, 225, 260, 300, 350, 400, 450, 500, 550, 600.
Automatic exposures
Automatic exposures are terminated when the radiation detector indicates that the required dose
has been reached. In this mode the kV is selected by the operator and mA is chosen to be the
maximum allowed mA for the selected kV and Hz (line frequency).
If the exposure time is longer than 1 sec (5 sec for the small focal spot) then a falling load tech-
nique is used. The exposure is started at the mA as specified in the following tables. The accu-
mulated dose is checked at 0.45 sec (2.45 sec for the small focal spot) and if it has reached more
than half of the required dose, the exposure can be continued at the same mA level, and will be
terminated within 1 second (5 seconds for the small focal spot) - well before the tube is over-
loaded.
If the accumulated dose is detected to be less than half of the required, a longer exposure time
than the one specified for the tube current can be expected. Therefore the tube current is
reduced at this time (after 0.45 or 2.45 sec exposure) to a lower mA that, when added to the
already produced tube loading, will not exceed the maximum tube rating. The falling load current
levels are listed in the two following tables.
Thermal ratings
Two separate methods are used to protect the tube from overload. One is measuring the tube
head enclosure temperature and if it exceeds 60 °C no further exposures are allowed until it falls
below 60 °C.
The other method keeps the average input power into the tube below or equal to 500W. The
exposure parameters are limited as indicated by the following tables, but this feature forces a
waiting time between the exposures to ensure that the average power into the tube never can
exceed this limit. For example if an exposure of 24 kV, 100 mA, 1 sec is performed a wait period
of 5 seconds is calculated and no further exposures are allowed until this time has elapsed.
There is no way to bypass these safety feature under any circumstances, and it is thus virtually
impossible to overload the X-ray tube.

Radiation leakage technique factors
The maximum-rated peak tube potential is 35 kVp and the maximum rated continuous tube cur-
rent is 3.5mA for the maximum-rated peak tube voltage.
Minimum filtration
The Beam-limiting device contains three different filtrations 30µm molybdenum, 25µm rhodium
and 0.50mm aluminum. The measured half-value layers are 0.343mmAl, 0.373mmAl and
0.377mmAl at 30kVp. These measured values correspond to aluminum equivalents of 0.55 -
0.65mmAl.
Rate line voltage

Maximum line current
Maximum 22 Amperes at absolute minimum stated mains voltage (187V~)
Technique factors that constitute the maximum line current condition
33kV / 97mA
Generator rating and duty cycle
3.2kW. The duty cycle and wait period can be calculated using the following formulas:
•Wait period = Tw = kV*mA*exp. Time / 500W
•Duty Cycle = 1 / (1 + kV*mA / 500W)
Maximum deviation of peak tube potential from indicated value
±2kV
Maximum deviation of tube current from indicated value
±5mA large focal spot, ±1mA small focal spot
Maximum deviation of exposure time tube current product from indicated value
±4mAs or ±10%, whichever is larger
Maximum deviation of exposure time from indicated value
±5%
Definition of measurement criteria
Exposure time
The beginning and end points of the exposure time are defined at 70% of the peak radiation
waveform measured with a calibrated x-ray monitor.
Peak tube potential
Is defined as the measured high voltage mean value measured with a calibrated non-invasive
kVp meter.
Tube current
Is defined using the resistance and voltage over the feedback resistor measured with a calibrated
multimeter. The mA value is then the voltage divided by the resistance.
mAs product
Is defined as the product of the exposure time and the tube current measurements.
