Abstract

Radiology installation comprising a set of instruments between which there is a flow of data signals. For the transmission of these signals, the installation comprises at least two loops between which the data can flow. Each loop is capable of transmitting data which does not flow through another loop. Preferably, there is a main loop and secondary or specialized loops.

Claims

1. A radiology installation, comprising:

a first plurality of instruments for using images produced from x-ray radiation which are connected in series to form a closed primary loop in which primary loop data flows between said first plurality of instruments;

a second plurality of instruments for using images produced from x-ray radiation which are connected in series to form a closed secondary loop in which secondary loop data flows between said second plurality of instruments;

controlling and monitoring means connecting to said closed primary loop and said closed secondary loop for controlling and monitoring said closed primary loop and said closed secondary loop and for coordinating communications between said closed primary loop and said closed secondary loop which are otherwise independent of each other; and

said controlling and monitoring means comprises a central handling unit which has a memory, said central handling unit having means for determining a configuration of said radiology installation so that a location of each instrument of said first plurality of instruments and a location of each instrument of said second plurality of instruments is registered in said central handling unit'"'"'s memory;

and an ancillary handling unit, said ancillary handling unit having means for transmitting a message from an instrument located in said first plurality of instruments to an instrument located in said plurality of instruments, said ancillary handling unit being located at a junction which connects said primary and secondary loops.

2. An installation according to claim 1, wherein:

said first plurality of instruments of said primary loop comprise a radiation monitor and control device, a digital processing device, an image monitoring device, and said controlling and monitoring device connected in series.

3. An installation according to claim 1, wherein:

said first plurality of instruments of said secondary loop comprise a power supply, table-positioning controls, a table for a patient, and a hoop bearing X-ray tubes and detectors, and a general control desk connected in series.

4. An installation according to claim 1, wherein:

each instrument of said plurality of instruments in said primary loop and said secondary loop has a communication device comprising an information circuit that processes information for said each instrument and a transmission circuit designed for the transmission of messages, said transmission circuit being connected between said information circuit and a connecting means connected to one of the loops consisting of said primary and secondary loops.

5. An installation according to claim 4, wherein:

said each instrument comprises a switch which is closed when problems arise in said each instrument so that the loop in which said each instrument is placed remains closed.

6. An installation according to claim 4, wherein:

said messages are transmitted by optical fibers, and said transmission circuit for the transmission of messages converts light into electrical signals at its input and converts electrical signals into light at its output.

7. An installation according to claim 1, wherein:

identical communication and processing devices are associated with each instrument of said plurality of instruments of said primary loop and said secondary loop.

8. A radiology installation, comprising:

a first plurality of instruments, for using images produced from x-ray radiation which are connected in series to form a closed primary loop in which primary loop data flows between said first plurality of instruments;

a second plurality of instruments for using images produced from x-ray radiation which are connected in series to form a closed secondary loop in which secondary loop data flows between said second plurality of instruments;

a third plurality of instruments for obtaining images produced from x-ray radiation which are connected in series to form a closed second secondary loop in which second secondary loop data flow between said third plurality of instruments;

controlling and monitoring means connected to said primary loop and said secondary loop for controlling and monitoring said primary loop, and for coordinating communication between said primary loop, said secondary loop and said second secondary loop which are otherwise independent of each other;

said controlling and monitoring means comprises a central handling unit which has a memory, said central handling unit having means for determining a configuration of said radiology installation so that a location of each instrument of said first plurality of instruments, said second plurality of instruments, and said third plurality of instruments is registered in said central handling unit'"'"'s memory; and

a first ancillary handling unit which connects said primary and said secondary loops and a second ancillary handling unit which connects said primary and said second secondary loops, said first and second ancillary handling units having means for transmitting messages between any of said instruments located in said primary, secondary and second secondary loops.

9. An installation according to claim 8, wherein:

said plurality of instruments of said second secondary loop comprise a collimator, a video camera, a photographic camera, a film-changing device and an image intensifier tube.

10. An installation according to claim 8, wherein:

said first plurality of instruments of said primary loop comprise a radiation monitor and control device, a digital processing device, an image monitoring device, and said controlling and monitoring device connected in series.

11. An installation according to claim 8, wherein:

said plurality of instruments of said secondary loop comprise a power supply, table-positioning controls, a table for a patient, and a hoop bearing X-ray tubes and detectors, and a general control desk connected in series.

12. An installation according to claim 8, wherein:

each instrument of said plurality of instruments in said primary loop, said secondary loop, and said second secondary loop has a communication device comprising an information circuit that processes information for said each instrument and a transmission circuit for the transmission of messages said transmission circuit being connected between said information circuit and a connecting means connected to one of the loops consisting of said primary, secondary and second secondary loops.

13. An installation according to claim 12, wherein:

each instrument comprises a switch which is closed when problems arise in said each instrument so that the loop in which said each instrument is placed remains closed.

14. An installation according to claim 8, wherein:

said messages are transmitted by optical fibers, and said transmission circuit for the transmission of messages converts light into electrical signals at its input and converts electrical signals into light at its output.

15. An installation according to claim 8, wherein:

identical communication and processing devices are associated with each instrument of said plurality of instruments of said primary loop, said secondary loop and said second secondary loop.
