CCR – Remote control for X-ray machines


The Remote Control Center, CCR onwards, is a centralization system for radioscopy equipment, and especially for Rapiscan brand equipment. With this centralization, it is possible to operate a set of radioscopy equipment with one or more operators from one station or several plants. Therefore, with the CCR system we can obtain the x-ray images of an equipment, move its conveyor belt, use the common image algorithms for these radioscopy equipment, activate installed active security systems, etc …

Thanks to the CCR system, it is possible to remotely assist the operation of a piece of equipment, helping in the event that it is necessary for the local operator to examine a suspicious package. Additionally, in the event that a local operator trained in radioscopy imaging is lacking, the CCR can take control of the equipment and perform the package inspection task remotely.

Since the control of the equipment can now leave the local area, the communications between the equipment and the center have been duly ensured, in such a way that it is practically impossible for any external agent to interfere in the communication.

CCR remote control of x-ray machines

The image shows the general structure for a CCR system. On the one hand we have x-ray equipment that may or may not have a specialized operator. These computers are connected to the local network or the internet as a communication medium (very widespread). On the other hand, the remote operators are in the CCR and from there, connected to the same network as the x-ray equipment remotely operate or assist the radioscopy elements.



The use case of a CCR system as an ASSISTANCE element offers the possibility of assisting and helping a local operator with problems or doubts in the study and / or decision of a package scanned by a radioscopy team.

The procedure turns the local operator into the person requesting the assistance of the CCR in the event of a suspicious package, at which time a CCR agent obtains control of the equipment, and between the two, the local agent and operator, study and decide on the package that at that time they have on screen. If at any time all CCR agents are busy, the system automatically stores the local operator request in a queue system waiting for any agent to be released. However, each agent is notified of the items that are queued, as well as their importance, if any.

The key feature of support is that any equipment feature that is activated, regardless of who activated that feature, will be visible to both observers, agent and operator.


The use case of a CCR system as AUTOMATIC control of a radioscopy equipment enables the agents of a CCR to control the equipment remotely as follows:

  1. Locally, there is a device that generates the call signal to the CCR, which can either be through a presence sensor or through a console. In the case of a sensor, this device detects the presence of the package on the tape and generates the call to the CCR. In the other case in which a console is used, it will be provided with a button to generate the call, and with a light signaling (green, yellow and red) to answer if the package is OK or Suspicious.
  2. A CCR agent receives the call, at which point the tape of the equipment in question begins to move until it leaves the lump inside the equipment. The agent receives the images and has the possibility of performing image functions, activating active security elements …
  3. Once it is decided on whether the package is OK or Suspect, the agent responds to the team, and only when we have the CCR console locally, on whether the package is OK or Suspect, and in turn will move the tape forward or backwards respectively.

As in the case of Assistance, if at any time all the CCR agents are busy, the system automatically stores the request of the local operator in a queue system waiting for any of the agents to be released. However, each agent is notified of the items that are queued, as well as their importance, if any.

The most important characteristics of the RAC are listed below, ordered by area:


  • It works on TCP / IP networks.
  • Communications protocol with high security encryption AES (Advanced Encryption Standard or Advanced Encryption Standard) and 256-bit key.
  • Compressed data in communication for a reduced waiting time in data transmission and reception.
  • Random key generation algorithm, that is, in each communication the system generates its own key, thus avoiding the use of stolen keys (practically impossible case due to the robustness of AES).
  • Multithreaded communication system, thus allowing the connection of several computers at the same time and through the same TCP port.

X-ray equipment

  • CCR Warning Device:
    • Tape sensor, through which the presence of a package is detected to generate a call to the CCR.
    • CCR Console, which by means of a button generates the call to the CCR.
  • Signaling: the CCR console alerts you if the scanned package is OK or Suspicious.
  • The functions generated by the CCR are viewed locally.
  • Possibility of activating active security systems: F.J.S. o Frequency Inhibitor System, …
  • Depending on the CCR response, the tape advances or reverses depending on whether the package is Accepted or Rejected.
  • Fully transparent for the local equipment, where a machine with a CCR module does not undergo any change in its normal operation, and can be used as autonomous and local equipment.

CCR Center

  • Multiplexed system: one or more operators for one or more machines.
  • Free agent search system, offering a team call to the agent who is currently free.
  • Queue system for calls, where if all agents are busy, the call is stored in said queue waiting for an agent to be free.
  • Queue priority system, where if different machines have different priorities, your calls will progress faster or slower through the call queue.
  • Access to CCR by User and Password.
  • Display of connected equipment and / or with some type of connection failure.
  • Friendly interface.
  • Internal and encrypted database.
  • The packages are stored in the system, giving the possibility of recovering and reviewing the stored images.
  • The system warns of the origin of the package, that is, what X-ray equipment it comes from.
  • It works under Windows operating systems, starting with Windows 2000.
  • It uses Microsoft’s .NET framework technology.
