Information processing apparatus, control method of information processing apparatus, radiation imaging system, and storage medium

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.

         10 . The apparatus according to  claim 9 , wherein the other 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
 the other control unit supplies the reset signal to the reset pin and resets the access to the storage unit by the control unit when the other control unit determines that it is impossible to access the storage unit by the control unit accessing the storage unit.   
     
     
         11 . The apparatus according to  claim 9 , wherein the other control unit performs the processing of resetting the access to the storage unit by the control unit by stopping power supply to the control unit when the other control unit determines that it is impossible to access the storage unit by the control unit accessing the storage unit. 
     
     
         12 . The apparatus according to  claim 9 , wherein the other control unit performs the processing of resetting the access to the storage unit by the control unit by controlling a switching element configured to switch a connection state of a line between the control unit and the storage unit, and setting the control unit and the storage unit in a non-connection state when the other control unit determines that it is impossible to access the storage unit by the control unit accessing the storage unit. 
     
     
         13 . The apparatus according to  claim 10 , further comprising:
 a success/failure determination unit configured to determine whether the processing of resetting the access to the storage unit by the control unit has succeeded;   a count unit configured to count the number of failures of the processing; and   an error output unit configured to output an error if the processing has failed a predetermined number of times, wherein   the other control unit performs the processing again upon determining that the processing has failed.   
     
     
         14 . The apparatus according to  claim 11 , further comprising:
 a success/failure determination unit configured to determine whether the processing of resetting the access to the storage unit by the control unit has succeeded;   a count unit configured to count the number of failures of the processing; and   an error output unit configured to output an error if the processing has failed a predetermined number of times, wherein   the other control unit performs the processing again upon determining that the processing has failed.   
     
     
         15 . The apparatus according to  claim 12 , further comprising:
 a success/failure determination unit configured to determine whether the processing of resetting the access to the storage unit by the control unit has succeeded;   a count unit configured to count the number of failures of the processing; and   an error output unit configured to output an error if the processing has failed a predetermined number of times, wherein   the other control unit performs the processing again upon determining that the processing has failed.   
     
     
         16 . A control method of 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, wherein the information processing apparatus comprises another 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 control unit by the other control unit;   a step of causing the other 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 other control unit.   
     
     
         17 . 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, a control unit configured to access to the storage unit, wherein the information processing apparatus comprises another 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 control unit by the other control unit;   a step of causing the other 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 other control unit.   
     
     
         18 . A radiation imaging system comprising:
