Abstract

A radiology device includes at least one gamma radiation sensor, an acquisition device arranged to acquire data from each gamma radiation sensor, a transmission device arranged to transmit the acquired data outside the device, at least one battery arranged to store electrical energy and to electrically supply each sensor, the acquisition device and the transmission device. The radiology device is arranged to be carried entirely by the user. An application of the present radiology device is the treatment of cancers by administration of radionuclides.

Claims

1. A radiology device for dosimetry, comprising:

at least one detector of gamma radiation comprising at least one first group and at least one second group, each of said at least one first group and each of said at least one second group comprising at least one gamma radiation detector;

acquisition means arranged for acquiring dosimetric reading data from each gamma radiation detector;

transmission means arranged for transmitting the acquired data to outside the device;

at least one battery arranged for storing electrical power and supply electricity to each detector, to the acquisition means and to the transmission means;

said device also comprising attachment means arranged for attaching at least one of the detectors to a part of the user'"'"'s body;

wherein the attachment means are arranged for acquiring from each gamma detector;

a gamma radiation measurement per unit of time as a function of time, or

a gamma radiation measurement as a function of time;

the device being made to be worn in its entirety by a user and its weight being less than one kilogram;

the acquisition means comprising a dedicated electronic acquisition module for each gamma radiation detector and integral with this detector;

the attachment means comprising a neck brace for the first group;

the first group comprising two detectors placed on a front face of the neck brace, symmetrically with respect to a plane of symmetry;

the second group being arranged for acting as a measurement reference for the first group.

2. The device according to claim 1, wherein the second group is not carried by the neck brace.

3. The device according to claim 1, wherein the transmission means are arranged for sending data to outside the device by a wireless link.

4. The device according to claim 1, wherein the transmission means comprise means for storing the data in the device.

5. The device according to claim 4, wherein the transmission means comprise means for transmitting data to outside the device by a wired connection, arranged for transmitting data after the acquisition of the data by the acquisition means and storage of the data by the storage means.

6. The device according to claim 1, wherein the attachment means comprise an item of clothing arranged to hold at least one of the detectors.

7. The device according to claim 1, wherein the transmission means and the at least one battery are grouped together in a case electrically connected to each detector by a wired connection arranged for supplying electricity to each detector via the at least one battery and for transferring data to the transmission means.

8. The device according to claim 1, further comprising at least one of means for measuring a heart rate and means for measuring a respiration rate of the user and means for synchronizing the acquisition of data from each gamma radiation detector with the heart rate and/or the respiration rate.
