1.2 Imaging Unit
The imaging unit consists of the sensor unit, sensor cable S150-60/P630, cover unit and sensor
information file unit.
(1) Converts the acquired X-ray image to light signal using the fluorescent screen and stores.
(2) After reading the stored electric signal (Image) from the sensor, perform the A/D conversion
and stores it on the frame memory temporally.
(3) Reduce the electric signal at the same time as storing and transfer it to the Control computer
through the Power Box.
(4) After the reduced images have been imported, the unit transfers the images in the frame
memory in the same way.
1.2.1 Sensor data file unit
The data unique to the sensor (LANMIT) are recorded on the file. The sensor data is recorded
inside the sensor unit, and automatically downloaded to the control PC as sensor data file by the
control software.
1.2.2 Sensor cable S150-60 (imaging unit side)
This cable on the imaging unit side is connected to the sensor cable P630 (power box
side) using a connector. It is used for the connection between the imaging unit and
power box, and it incorporates the following functions:
-Communication between the Imaging unit and Control computer via the power box.
-Power supply from the Power box to the Imaging unit.
-Communication between the Imaging units and Power Box.
The cable can be disconnected at the installation site by opening the access cover on the
rear panel of the imaging unit. However, this job should be performed only by a service
engineer or a medical engineer (ME) who has completed the service training, and users

1.2.3 Sensor cable P630 (power box side)
This cable on the power box side is connected to the sensor cable S150-60 (imaging unit
side) using a connector. It is used for the connection between the imaging unit and
power box, and it incorporates the following functions:
-Communication between the Imaging unit and Control computer via the power box.
-Power supply from the Power box to the Imaging unit.
-Communication between the Imaging units and Power Box.
The cable is connected by the connector on the power box side and users are permitted
to replace the cable.
The sensor cable P630 is 6.3 meters long.
