  Next, the operation of the medical image information management system 10 will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation of the medical image information management system 10 for collating medical image information from the image diagnostic apparatus 101.

  For example, examination of three subjects P (Pa to Pc) is performed on June 5, 2005 using the image diagnostic apparatus 101a1 of the image diagnostic apparatus 101.

  The medical image information management system 10 starts operation by causing the reader 11a1 of the reader unit 1 corresponding to the image diagnostic apparatus 101a1 to read the storage medium 100 of the subject P (step S1).

  When the reading operation of the storage medium 100 of the subject P is performed, the reader 11a1 reads the subject information of the subject P from the storage medium 100 and outputs it to the room entry history creation unit 31 of the image information matching unit 3 (step). S2).

  Based on the subject information of the subject P from the reader 11a1, the entrance history creation unit 31 includes, for example, the subject ID of the subject information, information on the entrance time when the subject information is received, and image diagnosis. The room entry history data including, for example, the apparatus ID “105” of the apparatus 101a1 is created and stored in the room entry history storage unit 32 (step S3).

  Next, for the examination of the subject P, after input operations such as subject information and imaging conditions of the subject P are performed from the operation unit of the diagnostic imaging apparatus 101a1 with human hands such as an operator, the subject P Is taken. After completion of the examination, medical image information obtained by adding examination information such as the device ID “105”, examination time, subject ID of the subject P, and photographing conditions to the image data obtained by photographing is stored in the medical information management system 10. Is output.

  The medical image information of the subject P received from the image diagnostic apparatus 101a1 is stored in the image information storage unit 2.

  Next, when a determination operation is performed on the subject Pa to Pc selected by setting the device ID “105” and the time range, for example, from the operation unit 6, the determination unit 33 reads the subject Pa from the entry history storage unit 32. The entrance history data having the device ID “105” corresponding to the inspection of Pc to Pc is read, and the examination information of the medical image information having the device ID “105” corresponding to the inspection of the subjects Pa to Pc is read from the image information storage unit 2. read out. Then, the read inspection information is checked against room entry history data to determine whether or not the inspection information includes erroneous information. (Step S4).

  If it is determined that the examination information of the medical image information does not include erroneous information (No in step S5), the process proceeds to step S8.

  FIG. 3 is a diagram illustrating an example of room entry history data and inspection information read by the determination unit 33 in step S4.

  The room entry history data 81 includes room entry history data 81a to 81c having an apparatus ID “105” created based on the examinations of the subjects Pa to Pc. The examination information 91 created according to the room entry history data 81 includes examination information 91a to 91d having the device ID “105”. The entry history data 81a to 81c are arranged from the top in the order of entry time, and the examination information 91a to 91d is arranged from the top in the order received from the image diagnostic apparatus 101a1.

  In the determination unit 33, the examination time and subject ID of each examination information 91a to 91d are compared with the entry time and subject ID of each entry history data 81a to 81c.

  The determination condition for determining that the inspection information 91 does not include erroneous information is that “the inspection time of each inspection information is later than the entry time of each corresponding entry history data”, “each inspection “The subject ID of the information is the same as the subject ID of each corresponding entry history data” and “Each examination information corresponds to all the entry history data”.

  First, the determination conditions “the examination time of each examination information is later than the entry time of each corresponding entry history data” and “the subject ID of each examination information is the subject of each entry history data corresponding to each entry information. The examination information 91a to 91d is determined according to “the same as the specimen ID”.

  The inspection time of the inspection information 91a is “9:45 on June 5, 2005”, and the entry history data having the entry time before this time is “9:10 on June 5, 2005”. Only the entry history data 81a having information is included. Since this room entry history data 81a has the same “142984” as the subject ID of the examination information 91a, the examination information 91a is considered to correspond to the room entry history data 81a.

  The entry history data having the entry time before the examination time “June 5, 2005 10:47” of the examination information 91b is the entry history data 81a to 81c, which is the same as the subject ID of the examination information 91b. It is the entry history data 81b having "132092". Therefore, the examination information 91b is regarded as corresponding to the room entry history data 81b.

  The entry history data having the entry time information prior to the examination time “June 5, 2005 11:15” of the examination information 91c is entry history data 81a to 81c. However, the room entry history data 81a to 81c does not include room entry history data having the same “123456” as the subject ID of the examination information 91c. Therefore, it is determined that the subject ID of the examination information 91c is incorrect information.

  Similarly to the examination information 91c, the subject ID “123456” of the examination information 91d is determined to be erroneous information.

  As described above, when it is determined that erroneous information is included in the examination information 91 (Yes in step S5 in FIG. 2), the determination unit 33 holds the medical image information of the examination information 91 in the image information holding unit 34. (Step S6 in FIG. 2). Next, along with a comment such as “Please correct the subject ID of the examination information 91c and 91d because it is incorrect”, for example, examination information 91c and 91d in which the subject ID of the erroneous information is emphasized is displayed on the display unit 5 ( Step S7 in FIG.

  The operator of the medical image information management system 10 viewing the comments and examination information displayed on the display unit 5 confirms with the operator of the image diagnostic apparatus 101a1 and corrects the erroneous information part of the examination information from the operation unit 6. Input operation to do.

  When the correction input operation to “123457”, for example, is performed on the subject IDs of the examination information 91c and 91d from the operation unit 6, the determination unit 33 holds in the image information storage unit 2 and the image information holding unit 34. The erroneous information part of the examination information 91c and 91d of the medical image information having the examination information 91 that has been used is replaced with correction input information from the system control unit 7. Accordingly, the determination unit 33 determines that the examination information 91 does not include erroneous information because the examination information 91 conforms to all the determination conditions, and the medical information having the corrected examination information 91 of the image information holding unit 34. The image information is moved and stored in the image information storage unit 4 (step S8 in FIG. 2).

  In this case, if the examination is performed in the order of the subjects Pa, Pb, and Pc by the diagnostic imaging apparatus 101a1, the room entry history data 81c corresponds to the subject Pc. Then, the examination of the subject Pc is performed twice, and the subject ID is erroneously inputted at the time of the input operation of the examination information 91c of the first examination. Further, in the input operation of the inspection information 91d, the same error occurs because the inspection information 91c is used.

  After the corrected medical image information is stored in the image information storage unit 4, the medical image information management system 10 ends the operation (step S9).

  Thereafter, a doctor who performs image diagnosis of the subject P reads out the image data of the subject P from the image information storage unit 4 and displays it on the display unit 5, and the image data is read.

  FIG. 4 is a diagram illustrating another example of the room entry history data and the inspection information read by the determination unit 33 in step S4.

  The room entry history data 82 includes room entry history data 82a to 82c having an apparatus ID “105” created based on examinations of the subjects Pa to Pc. The examination information 92 created according to the room entry history data 82 includes examination information 92a to 92c having the device ID “105”. The room entry history data 82a to 82c are arranged from the top in the oldest entry time, and the examination information 92a to 92c are arranged from the top in the order received from the image diagnostic apparatus 101a1.

  In the determination unit 33, first, the determination conditions “examination time of each examination information is later than the entry time of each corresponding entry history data” and “the subject ID of each examination information is the corresponding entry history The examination information 92a to 92c is determined according to “the same as the subject ID of the data”.

  The examination time of the examination information 92a is “05:05 on June 5, 2005”, and the entry history data having the entry time before this time is “05:05 on June 5, 2005”. Only the entry history data 82a having information is included. Since this room entry history data 82a has the same “123456” as the subject ID of the examination information 92a, the examination information 92a is considered to correspond to the room entry history data 82a.

  The entry history data having the entry time before the examination time “June 5, 2005 11:15” of the examination information 92b is the entry history data 82a to 82c, which is the same as the subject ID of the examination information 92b. It is only the entry history data 82a having "123456". Therefore, the examination information 92b is regarded as corresponding to the room entry history data 82a.

  The examination time of the examination information 92c is “June 5, 2005 11:34”, and the entry history data having the entry time before this time is the entry history data 82a to 82c. Only the entry history data 82c has the same “153742” as the subject ID. Therefore, the examination information 92c is regarded as corresponding to the room entry history data 82c.

  However, since each inspection information 92a to 92c does not correspond to the room entry history data 82b, it does not conform to the determination condition “each inspection information corresponds to all the room entry history data”. Each of the entry history data 82a to 82c and each of the examination information 92a and 92c are arranged in time series from the top and are the same number of pieces of information, and therefore the subject of the examination information 92b that does not correspond to the entry history data 82b. It is determined that the ID “123456” is erroneous information.

  In this case, the image diagnostic apparatus 101a1 uses the examination information 92a of the subject Pa to input the examination information 92b of the subject Pb, and changes and inputs the subject ID “123456” of the examination information 92a to “132093”. I forgot to make an error.

  According to the embodiment of the present invention described above, the entrance history data created based on the subject information of the subject P and the examination information of the medical image information of the subject P obtained from the image diagnostic apparatus 101 are obtained. When it is determined that erroneous information is included in the examination information of the medical image information, the medical image information is held in the image information holding unit 34 and the erroneous information is displayed on the display unit 5. When it is determined that the examination information of the medical image information from the image diagnostic apparatus 101 does not include erroneous information, the medical image information can be stored in the image information storage unit 4.

  Further, when erroneous information is corrected from the operation unit 6, the corrected medical image information can be stored in the image information storage unit 4.

  As a result, misdiagnosis due to image diagnosis using medical image information from the image information storage unit 4 can be prevented.
