16 Service Manual 200569
2. Unit Description Cranex Novus
2.5 Electrical description
Circuit boards
Circuit boards are described in detail in section 3. Circuit Boards.
Power supply
Power (230VAC or 115VAC) is supplied to the unit
through L100 (Z-Motor Driver). From L100, power is
routed through the Generator board to a transformer
which produces low voltages (+3, +3.3, +5, -9.4, +15
and +24V) that are supplied to L200, a linear mode
power supply, which distributes the voltages to the
other boards in the unit. The transformer also produces
27VAC and 19VAC voltages that are supplied directly
(not through L200) to the Generator board.
The power for the AC-motor (z-motor), 230VAC or
115VAC, is taken directly from L100 and not from the
Generator board.
Capacitors on the Generator board produce the 310V
needed to power the tubehead from the 230VAC or
115VAC supplied by L100.
Main fuses
Two 5AT/230VAC or 8AT/115VAC, dimensions 5mm x
20mm, UL approved.
They are located below the main power supply cable at
the rear of the column.
Service Manual 200569 17
Cranex Novus 2. Unit Description
Unit control
The unit is controlled by a microprocessor on L400
(CPU board). It continually monitors and controls the
operation of the unit. A serial peripheral interface communication protocol (SPI - RS485) and direct digital I/O
are used to monitor most of the unit functions.
The microprocessor:
- monitors the optosensors
- monitors control panel keys
- controls unit movements during exposures
- starts, controls and stops x-ray generation
- controls the digital imaging chain
The necessary unit settings and parameters for all the
imaging programs are stored in the memory which is
also on L400.
Motors and motor control
There is one stepper motor and one AC-motor in the
unit.
The stepper motor drives the rotating unit (R-movement). The stepper motor is driven and controlled by
L300 (3-Phase Microstepper Driver).
The AC-motor (Z-motor) adjusts the height of the unit
(Z-movement), and the motor is activated by L100. To
activate the Z-motor L100 must receive a control signal
from L400 and a separate control (enable) signal from
the Z-movement (up/down) keys.
An emergency switch on the front of unit disables the Zmotor (Z-movement) and stepper motor (R-movement)
when pressed.
18 Service Manual 200569
2. Unit Description Cranex Novus
Exposure logic
An exposure can only be taken when the unit is in the
ready state (the exposure ready light on the control
panel is on) and the exposure button is pressed and
held down.
The Generator board receives the correct kV and mA
references from the CPU (L400). A few milliseconds
after the exposure button is pressed (Expsw) preheat
is enabled (Preh). After 800ms the exposure will start
(ExpEna). The tubehead will receive power from the
Generator board and the Generator board will also start
to regulate the mA and kV according to mA- and kVfeedback.
Service Manual 200569 19
Cranex Novus 2. Unit Description
Position control
The position of the rotating unit (R-movement) is monitored by optosensors on N2500 (Rotation Position Sensor Circuit). The optosensors indicate in which sector
the rotating unit is. The optosensors ensure that the
rotating unit is in the correct position, start or PIO (Patient In/Out), for an exposure.
The statuses of the optosensors are monitored continually by the unit software.
The upper and lower limits of the vertical carriage (Zmovement) are monitored by microswitches.
A overview of the Imaging Chain
This description assumes that the unit is ready to take
an exposure.
Image acquisition is controlled by a software component, Digora Software Driver (DSD) which is installed in
the PC connected to the unit.
When an exposure is taken L400 (the CPU) then sends
a PPOWER (pan) and CCDON signal. CCDON signal
activates
linear regulators on L200 which then produce
the power supply voltages for the CCD sensor.
The CPU's control software continuously monitors the
status of the connection with the DSD driver. After image exposure but before image transfer the CPU sends
a label that includes the imaging parameters (—kV/—
mA/ —s) and an imaging program identifi er.
The CPU enables the IMAGE signal to activate pixel
clocking. The CPU then produces the TDI clock signal,
which clocks the pixels from the CCD sensor. Derivation
of several CCD clock signals from the TDI clock is done
by the CCD sensor board.
Radiation striking the CCD sensor is converted to visible light which is detected by the CCD cell. A binning
procedure is carried out on individual pixels, i.e. two adjacent pixels in a row and column (2 x 2 binning) forms
one large pixel (96µm x 96µm). The output voltage of
the CCD is fed to a 14-bit A/D converter.
20 Service Manual 200569
2. Unit Description Cranex Novus
The CCD sensor board sends the image data (now 12
bits) to the CPU board where they are saved on the
SDRAM. The image information is transferred to the PC
via the Ethernet cable.
In the PC there is a Network Interface Card (NIC). After
image data transfer the DSD preprocesses the raw
image, for example it interpolates gaps between CCD
chips, and carries out dark current correction and gain
correction (the pixels do not have equal characteristics).
