Abstract

According to one embodiment, a medical image processing apparatus includes a memory, an information collector and a determiner. The memory stores DICOM image data including study information. The information collector collects information relating to general-purpose image data incompatible with DICOM. The determiner determines whether designated general-purpose image data is related to a study which generates the DICOM image data, based on information collected by the information collector and the study information.

First claim

The invention claimed is:

1. A medical image processing apparatus, comprising:
a memory to store DICOM (Digital Imaging and Communication in Medicine) image data including study information generated from a study for a patient on a particular date and having a DICOM tag, the DICOM image data being obtained from a medical image diagnosis apparatus; and
processing circuitry configured to
collect general-purpose information relating to general-purpose image data incompatible with DICOM, the general-purpose image data not having the DICOM tag and being generated by an apparatus different from the medical image processing apparatus,
determine whether a date associated with the general-purpose image data is compatible with the particular date of the study which generated the DICOM image data, based on the general-purpose information and the study information,
output a warning of misidentification of the patient indicating that the patient might be misidentified in response to a result of the determination,
collect storage information relating to the general-purpose image data,
generate event information related to the study in which the DICOM image data is generated, and
collect appendant data pertaining to the general-purpose image data, and/or add, to the general-purpose image data, metadata representing what is indicated by the general-purpose image data,
generate comparison information based on the storage information, the event information, and at least one of the appendant data and the metadata, and
determine whether the general-purpose image data is related to the study, based on the generated comparison information.

2. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to determine whether the general-purpose image data is related to the study, based on the general-purpose information, which includes the date and is attached to the general-purpose image data.

3. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to add attribute information representing a kind of study to the general-purpose image data, and
determine whether the general-purpose image data is related to the study, based on the attribute information representing the kind of study.

4. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to determine whether the general-purpose image data is related to the study, based on the general-purpose information of the date attached to the general-purpose image data or date information included in study history records of the patient.

5. The medical image processing apparatus according to claim 2 , wherein the processing circuitry is further configured to determine that the general-purpose image data is related to the study when information identical to information other than the date is included in the study information and that the date is within an allowable period determined based on the particular date of the study.

6. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to
generate comparison information based on the general-purpose information, and
determine whether the general-purpose image data is related to the study, based on the comparison information.

7. The medical image processing apparatus according to claim 6 , wherein the processing circuitry is further configured to determine that the general-purpose image data is related to the study when study information identical to the generated comparison information is included in information obtained from a study information memory.

8. The medical image processing apparatus according to claim 6 , wherein the processing circuitry is further configured to
input metadata representing what is indicated by the general-purpose data, and
collect at least the metadata, information indicating a storage location of the memory in which a file is stored, and information on the date attached to the general-purpose image data,
wherein the comparison information includes information on a kind of study based on the metadata, information on the storage location, and information on the particular date of the study based on the information on the date.

9. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to display the warning.

10. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to
collect the appendant data pertaining to the general-purpose image data;
add, to the general-purpose image data, the metadata representing what is indicated by the general-purpose image data; and
generate the comparison information based on the storage information, the appendant data, the event information, and the metadata.

11. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to
collect storage information relating to the general-purpose image data;
collect appendant data pertaining to the general-purpose image data;
generate comparison information based on the storage information and the appendant data; and
determine whether the general-purpose image data is related to the study, based on the generated comparison information.

12. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to
collect storage information relating to the general-purpose image data;
collect appendant data pertaining to the general-purpose image data;
collect symbol information included in the general-purpose image data based on image recognition technology;
generate comparison information based on the storage information, the appendant data and the symbol information; and
determine whether the general-purpose image data is related to the study, based on the generated comparison information.

13. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to
collect storage information relating to the general-purpose image data;
collect appendant data pertaining to the general-purpose image data;
recognize location information representing where the general-purpose image data is generated;
generate comparison information based on the storage information, the appendant data and the location information; and
determine whether the general-purpose image data is related to the study, based on the generated comparison information.

14. The medical image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to
collect storage information relating to the general-purpose image data;
collect appendant data pertaining to the general-purpose image data;
obtain image generation apparatus information regarding an image generation apparatus that created the general-purpose image data; and
generate comparison information based on the storage information, the appendant data and the image generation apparatus information; and
determine whether the general-purpose image data is related to the study, based on the generated comparison information.

15. The medical image processing apparatus of claim 10 , wherein the processing circuitry is further configured to collect, as the appendant data, at least one of the data of photography of an image file, a vendor name, position information, and a type of photography device.
