Ca au ut ti io on n R Re eg ga ar rd di in ng g t th he e S Se et tu up p
According to the “IEC 60601-1-1:2000”, equipments installed in the patient environment are
restricted to “medical electric equipment conforming to IEC 60601-1”.
Note that the entire radiography system, including this product, is required to comply with IEC
60601-1-1. The details are as follows: Medical equipment such as an X-ray generator
complying with IEC 60601-1, an image capture computer and a display monitor complying with
IEC 60601-1 or IEC 60950-1.
The image capture computer, optional devices such as network equipment or magnetic card
readers, and display monitors that are classified as other than medical electrical equipment (IEC
60601), for example as information technology equipment (IEC 60950), cannot be installed in
the patient environment.
The appended documentation is to be provided to the user, operator, and installer of the
equipment configuring the system, such as the image capture computer and display monitor,
upon installation of such equipment.
Also, for the installation, the above items must be connected to a common protective earth.
Equipment connected to the image capture computer must satisfy state No. 3 in table BBB.201
of IEC 60601-1-1.
Either connect the image capture computer to a common protective ground, add a dedicated
protective ground, or install an isolation device.
The patient environment described below is an example cited from the “IEC 60601-1-1:2000” –
the measurements are only guidelines. However, the “IEC 60601-1-1:2000” example must be
treated as the standard.
Therefore, the image capture computer, optional devices such as network equipment or
magnetic card readers, and display monitors must be installed in a location separated by at least
the dimensions indicated below (outside the patient environment). In addition, the X-ray
interface box should be installed outside the patient environment.
* The areas through which patients move at times other than X-ray exposure (when
entering and leaving, etc.) are also included in the patient environment. Therefore,
always confirm (discuss) with the customer that the installation location is outside the
patient environment.
Example of patient environment

Note: These measurements are only guidelines.

1. Overview
CXDI-80C Wireless
The CXDI-80C Wireless is a slim-line lightweight flat panel detector (FPD) which has no
cables for communication or power supply and which has other features as well that are
designed for optimum ease of use. It uses the IEEE 802.11n (2.4 GHz/5 GHz) standard and can
display images at higher speeds than existing products.
The size of this FPD is the same as a film cassette complying with the ISO4090 standard, and it
enables digital radiography using existing analog radiography equipment. It has a light weight
of about 2.3 kg including the battery, and it delivers excellent operability.
The FPD realizes high resolution with a pixel pitch of 125 µm and employs cesium iodide (CsI)
for the scintillator to achieve enhanced sensitivity.
The CXDI-80C Wireless maintains system compatibility with the CXDI-70C Wireless,
allowing both to be used side-by-side in the same environment. In addition, an existing
installation can be used as is with the CXDI-80C Wireless, thereby minimizing the costs
associated with adding the CXDI-80C Wireless.
CXDI system software CXDI Control Software NE supported:
With Ver.1.40 or later
CXDI Controller RF: With Ver.1.40 or later
80C detector body No. 100001 or later
X-ray interface box body No. 100001 or later
AC/DC box body No. 100001 or later
* Intended uses and applications
Diagnosis, prevention and monitoring of the diseases of patients
Exposing patients to X-rays, detecting the X-rays passed through the bodies of the patients and
converting them into digital images which are then provided to the physicians for diagnosis
Anticipated usage environments: X-ray exposure rooms, wards in general, health screening
vans
Anticipated users: Radiologists, physicians
Parties expected to install unit: Sales companies or agents which have received specialized
training
Anticipated examinees: Patients
* Precautions for use
No guarantees are given for the system in terms of risk management control in regard to
providing protection from blood and chemicals in operating theaters (water-proof performance)
or assuring safety and hygiene or when it is used together with cardiac defibrillators in ICUs and
other locations, used outdoors or used in applications oriented toward animals. Operation of the
product in such circumstances must be performed under the responsibility and assurances of SI
(System Integrator) after the operating ranges allowed by the product’s specifications have been
fully understood and acknowledged.

3.1 CXDI-80C Wireless System configuration
To use this system, users can select between a wireless connection and wired connection as shown in the
figures below. The wired connection option is useful when the detector is to be permanently installed in
an upright stand for use. Communication and the supply of power are made possible through the
detector cables.

3.2 System compatibility with CXDI-70C Wireless
The CXDI-80C Wireless uses the same system components as the CXDI-70C Wireless, as shown
below.
3.3 Restrictions on connections
The control software that can be connected to the product is Ver.1.40 and up. The number of units
which can be connected is restricted as below by the software requirements.
Registered units: 10, simultaneously connected units: 4
The hardware requirements do not impose restrictions, but communication performance may be
degraded by interference when wireless channels are shared.
No such restrictions apply to wired connections.
◆Handling of ferrite cores
(1) [70C Wireless (2.4 GHz compatible)]
The system conforms to IEC 60601-1-2 when ferrite cores are attached to the detector cable and to the
LAN cable used to connect to the X-ray interface box.
It is therefore necessary to attach ferrite cores to these two cables in order to use the system.
(2) [70C Wireless (2.4 GHz/5 GHz compatible)]
The system conforms to IEC 60601-1-2 when no ferrite cores are attached to the sensor cable and to the
LAN cable used to connect to the X-ray interface box.
It is therefore not necessary to attach ferrite cores to these two cables in order to use the system.
Note: Caution on mixed usage of different detector models
If any of the detectors used is the 70C Wireless (2.4 GHz compatible) model, ferrite cores must be
attached to the two cables.

4.1 Processing flow
4.2 Concerning each type of image
(1) Raw images
These are the images obtained by LANMIT. They have not been compensated or corrected
in any way.
