Abstract

Measurement results are acquired by a number of medical imaging systems in each case using a respective measurement protocol and by applying a respective dose. Data records are automatically placed in a cloud by the systems or a PACS connected to the respective system. Measurement protocols, applied doses, and anonymized images of the data records are referenced among each other. The data records placed in the cloud are assigned the respective examination type and an identification of the respective system and/or an identification of the type of respective system. The cloud accepts data queries from users. The data queries as a search criterion specify at least the examination type, the identification of the respective system, and/or the identification of the type of the respective system. The data records are determined by the cloud in accordance with the respective data query and are made available to the respective user.

First claim

The invention claimed is:

1. An evaluation method for medical data, the evaluation method comprising:
acquiring, by a number of medical imaging systems, measurement results using a respective measurement protocol and by applying a respective dose, wherein the respective measurement protocol is used to operate a respective medical imaging system; and
automatically placing, in each case, data records in a cloud by the medical imaging systems or a PACS connected to the respective medical imaging system, the data records including at least the respective measurement protocol used, the respective applied dose, and in anonymized form, images derived in each case from the acquired measurement results,
wherein the measurement protocols, the applied doses, and the anonymized images of respective data records are referenced among one another as linked data items, such that locating one of the linked data items allows the other linked data items to be located,
wherein a respective examination type and an identification of the respective medical imaging system, an identification of the type of respective medical imaging system, or a combination thereof are assigned to the data records placed in the cloud, the respective examination type indicative of a specific region of an object being measured by the respective medical imaging system,
wherein the cloud accepts respective data queries from respective users,
wherein the respective data queries as a search criterion at least specify the examination type and the identification of the respective medical imaging system, the identification of the type of the respective medical imaging system, or any combination thereof,
wherein the cloud identifies a subset of the data records placed in the cloud according to each of the respective data queries and makes available the subset of the data records to the respective users, and
wherein the respective users additionally specify in the respective data queries a type of data to be supplied to the respective users as respective results of the respective data queries, the type of data being the respective measurement protocol used, the respective applied dose, the respective anonymized images, or any combination thereof.

2. The evaluation method of claim 1 , wherein the data records placed automatically in the cloud by the medical imaging systems or the PACS connected to the respective medical imaging system also comprise data derived from the images in anonymized form, and wherein the data is also linked to remaining data of the respective data records.

3. The evaluation method of claim 1 , wherein the data records placed automatically in the cloud by the medical imaging systems or the PACS connected to the respective medical imaging system comprise additional data of the image acquisition, and wherein the data is also linked to remaining data of the respective data records.

4. The evaluation method of claim 1 , further comprising placing non-anonymized image data in the cloud in a form that is protected from unauthorized access by the medical imaging systems or the PACS connected to the respective medical imaging system.

5. The evaluation method of claim 4 , wherein the non-anonymized image data is placed in the cloud as independent data records but has a reference to the data record containing the measurement protocol used and the applied dose.

6. The evaluation method of claim 1 , wherein the medical imaging systems comprise an x-ray system, a CT-scanner, a C-arm system, another medical imaging system, or any combination thereof.

7. The evaluation method of claim 2 , wherein the data records placed automatically in the cloud by the medical imaging systems or the PACS connected to the respective medical imaging system comprise additional data of the image acquisition, and
wherein the data is also linked to the remaining data of the respective data records.

8. The evaluation method of claim 2 , further comprising placing non-anonymized image data in the cloud in a form that is protected from unauthorized access by the medical imaging systems or the PACS connected to the respective medical imaging system.

9. The evaluation method of claim 3 , further comprising placing non-anonymized image data in the cloud in a form that is protected from unauthorized access by the medical imaging systems or the PACS connected to the respective medical imaging system.

10. The evaluation method of claim 2 , wherein the medical imaging systems comprise an x-ray system, a CT-scanner, a C-arm system, another medical imaging system, or any combination thereof.

11. The evaluation method of claim 3 , wherein the medical imaging systems comprise an x-ray system, a CT-scanner, a C-arm system, another medical imaging system, or any combination thereof.

12. The evaluation method of claim 4 , wherein the medical imaging systems comprise an x-ray system, a CT-scanner, a C-arm system, another medical imaging system, or any combination thereof.

13. The evaluation method of claim 5 , wherein the medical imaging systems comprise an x-ray system, a CT-scanner, a C-arm system, another medical imaging system, or any combination thereof.

14. The evaluation method of claim 1 , wherein the respective examination type and the identification of the respective medical imaging system are assigned to the data records placed in the cloud, and wherein the respective data queries as a search criterion at least specify the examination type and the identification of the respective medical imaging system.

15. The evaluation method of claim 1 , wherein a possibility is offered to the respective users of the cloud, based on the data records made available to the respective users, to retrieve additional contents of the data records.

16. An evaluation method for medical data, the evaluation method comprising:
acquiring, by a number of medical imaging systems, measurement results using a respective measurement protocol and by applying a respective dose; and
automatically placing, in each case, data records in a cloud database by the medical imaging systems or a PACS connected to the respective medical imaging system, the data records including at least the respective measurement protocol used, the respective applied dose, and in anonymized form, images derived in each case from the acquired measurement results,
wherein the measurement protocols, the applied doses, and the anonymized images of respective data records are referenced among one another,
wherein a respective examination type and an identification of the respective medical imaging system, an identification of the type of respective medical imaging system, or a combination thereof are assigned to the data records placed in the cloud database, the respective examination type indicative of a specific region of an object being measured by the respective medical imaging system,
wherein the cloud database accepts respective data queries from respective users,
wherein the respective data queries as a search criterion at least specify the examination type and the identification of the respective medical imaging system, the identification of the type of the respective medical imaging system, or any combination thereof,
wherein the cloud database determines a subset of the data records placed in the cloud database according to each of the respective data queries and makes available the subset of the data records to the respective users, and
wherein the respective users additionally specify in the respective data queries a type of data to be supplied to the respective users as respective results of the respective data que
