Abstract

An information processing apparatus connected to an external connection unit of a radiation imaging apparatus including a storage unit and a control unit configured to access to the storage unit, comprises a determination unit that determines that an abnormality has occurred in the radiation imaging apparatus; a processing unit that, if determined that the abnormality has occurred, and the control unit has access authority to the storage unit, performs processing of revoking the access authority; another control unit that obtains the access authority in accordance with the processing of the processing unit and accesses the storage unit; and an output unit that outputs, to an external apparatus, any one of radiation image data captured by the radiation imaging apparatus and log data of the apparatus which are obtained from the storage unit via the other control unit.

First claim

What is claimed is:

1. An information processing apparatus connected to an external connection unit of a radiation imaging apparatus including a storage unit and an imaging-apparatus control unit configured to access the storage unit, comprising:
second control unit that is capable of accessing the storage unit; and
an output unit configured to output, to an external apparatus, at least one of radiation image data captured by the radiation imaging apparatus and log data of the radiation imaging apparatus which are obtained from the storage unit via the second control unit;
wherein in a case in which it is determined by the imaging-apparatus control unit or the second control unit that an abnormality has occurred in the radiation imaging apparatus, the second control unit accesses the storage unit.

2. The apparatus according to claim 1 , wherein the second control unit includes a circuit that is connected so as to be able to supply a reset signal to a reset pin of the control unit via a line, and
in the case in which the second control unit determines that it is impossible to access the storage unit by the imaging-apparatus control unit accessing the storage unit, the second control unit supplies the reset signal to the reset pin and resets the access to the storage unit by the imaging-apparatus control unit.

3. The apparatus according to claim 1 , wherein the second control unit performs the processing of resetting the access to the storage unit by the imaging-apparatus control unit by stopping power supply to the first control unit, in the case in which the second control unit determines that it is impossible to access the storage unit by the imaging-apparatus control unit accessing the storage unit.

4. The apparatus according to claim 1 , wherein the second control unit performs the processing of resetting the access to the storage unit by the imaging-apparatus control unit by controlling a switching element configured to switch a connection state of a line between the imaging-apparatus control unit and the storage unit and setting the control unit and the storage unit in a non-connection state, in the case in which the second control unit determines that it is impossible to access the storage unit by the imaging-apparatus control unit accessing the storage unit.

5. The apparatus according to claim 2 , further comprising:
a success/failure determination unit configured to determine whether the processing of resetting the access to the storage unit by the imaging-apparatus control unit has succeeded; and
a count unit configured to count the number of failures of the processing,
wherein upon determining that the processing has failed, the second control unit performs the processing again, and
wherein the apparatus further comprises an error output unit configured to output an error if the processing has failed a predetermined number of times.

6. A control method of an information processing apparatus connected to an external connection unit of a radiation imaging apparatus including a storage unit, and an imaging-apparatus control unit configured to access to the storage unit, wherein the information processing apparatus comprises a second control unit that is capable of accessing the storage unit, the control method comprising:
a determination step of determining that an abnormality has occurred in the radiation imaging apparatus by the imaging-apparatus control unit or the second control unit;
a step of causing the second control unit to access the storage unit in a case where it is determined in the determination step that the abnormality has occurred; and
an output step of outputting, to an external apparatus, at least one of radiation image data captured by the radiation imaging apparatus and log data of the radiation imaging apparatus which are obtained from the storage unit via the second control unit.

7. A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute the steps of a control method of an information processing apparatus connected to an external connection unit of a radiation imaging apparatus including a storage unit, an imaging-apparatus control unit configured to access to the storage unit, wherein the information processing apparatus comprises a second control unit that is capable of accessing the storage unit, the control method comprising:
a determination step of determining that an abnormality has occurred in the radiation imaging apparatus by the imaging-apparatus control unit or the second control unit;
a step of causing the second control unit to access the storage unit in a case in which it is determined in the determination step that the abnormality has occurred; and
an output step of outputting, to an external apparatus, at least one of radiation image data captured by the radiation imaging apparatus and log data of the radiation imaging apparatus which are obtained from the storage unit via the second control unit.

8. A radiation imaging system including an information processing apparatus connected to an external connection unit of a radiation imaging apparatus including a storage unit and an imaging-apparatus control unit configured to access to the storage unit, comprising:
second control unit that is capable of accessing the storage unit; and
an output unit configured to output, to an external apparatus, at least one of radiation image data captured by the radiation imaging apparatus and log data of the radiation imaging apparatus which are obtained from the storage unit via the second control unit,
wherein in a case in which it is determined by the imaging-apparatus control unit or the second control unit that an abnormality has occurred in the radiation imaging apparatus, the second control unit accesses the storage unit.

9. The apparatus according to claim 3 , further comprising:
a success/failure determination unit configured to determine whether the processing of resetting the access to the storage unit by the imaging-apparatus control unit has succeeded; and
a count unit configured to count the number of failures of the processing,
wherein upon determining that the processing has failed, the second control unit performs the processing again, and
the apparatus further comprises an error output unit configured to output an error if the processing has failed a predetermined number of times.

10. The apparatus according to claim 4 , further comprising:
a success/failure determination unit configured to determine whether the processing of resetting the access to the storage unit by the imaging-apparatus control unit has succeeded; and
a count unit configured to count the number of failures of the processing,
wherein upon determining that the processing has failed, the second control unit performs the processing again, and
the apparatus further comprises an error output unit configured to output an error if the processing has failed a predetermined number of times.
