Next, the feedback index concerning the displayed conference information is input via an input unit (step 606). Here, the feedback index is a value or information indicating the feedback degree of the conference information for reference in a future conference. This feedback index is input for each item via the input unit by the user.
It is to be noted that the feedback index is not limited to the example of
Next, the conference information display•feedback section 63 transmits, to the information collecting•update•addition unit 38, the conference result including the feedback index, the radiogram interpretation result, the correction of the imaging conditions, the evaluation with respect to the case and the like for each input item. The information collecting•update•addition unit 38 performs change such as the update or the addition of the contents of the database 37 (the information table 371) to execute the feedback of the conference result (step 607).
Next, when the conference is executed again and the instruction for the conference display corresponding to the case name is output in response to the user's request in the same manner as described above, the flow chart shown in
Subsequently, when the conference is similarly executed, the information of the conference display is collected based on the contents of the information table 371, and displayed in the TV monitor. Then, while referring to this displayed conference information, the conference is performed, and this conference result is fed back by the conference information display•feedback section 63. Furthermore, the contents of the information table 371 are updated in preparation for the next collection of the information of the conference display.
Therefore, in this case, the medical image is acquired by the medical image imaging apparatus 2, the object information on the medical image is generated, and the medical image and the object information on the medical image are stored in the data storage unit 36 and the database 37. Moreover, the case information corresponding to the case name based on the object information for each patient and the information of the medical image are stored in the information table 371. The case information for each patient read from the information table 371 corresponding to the case name in accordance with the conference instruction, and the medical image read in accordance with the information of the medical image of the information table 371 are collected as the conference information. The conference display of the collected information is performed. Moreover, the conference result based on the displayed contents is fed back to the information table 371 by the conference information display•feedback section 63 to change the contents. In consequence, the case information and the medical image for each patient based on the object information used in the past conference are effectively used in the reference or the investigation during the conference. Furthermore, the result obtained by this conference is fed back to the information table 371, and reflected as a judgment material such as a diagnosis course for the next conference, so that the object information and the medical image used in the past conference can repeatedly effectively be used. Moreover, since the case information and the medical image corresponding to the case name are collected as the information of the conference display based on the information table 371 changed in accordance with the conference result, the plurality of doctors can diagnose the patient and determine the diagnosis plan by the conference based on the latest conference information to be updated, so that precise conference can be realized.
Next, a second embodiment of the present invention will be described. In the present embodiment, the searching of conference information by use of a feedback index will be described.
