Abstract

An image display method and an image display apparatus realize prevention of misdiagnosis which is caused by corruption of a part of at least one type of information including identification information, information on a series of images, and diagnosis-report information. The image display method and the image display apparatus perform an operation using a predetermined hash function on patient information ID1, examination information ID2, a series of images I1 to In acquired by an intra-subject information acquiring apparatus to generate and add hash data h. Thereafter, the image display method and the image display apparatus, when using case 15a-1, perform an operation using a predetermined hash function to generate new hash data, compare each piece of the hash data h already added and newly generated hash data, and determine whether two pieces of hash data match with each other. Based on the result of determination, the use of the case data is canceled, or display of corrupted image is restricted, for example, so that the misdiagnosis is prevented.

Claims

1. An image display method comprising:

generating first information by performing an operation using one of a predetermined function and an operation expression on at least one type of information of identification information including patient information and examination information, information on a series of images acquired by an intra-subject information acquiring apparatus, and diagnosis-report information formulated and updated based on the identification information and the information on a series of images, and by generating and adding first error detection information;

generating second information by performing an operation using one of the predetermined function and the operation expression on at least one type of information to be output among the at least one type of information, and generating second error detection information; and

determining whether the first error detection information and the second error detection information match with each other by comparing the first error detection information and the second error detection information.

2. The image display method according to claim 1, further comprising

prohibiting a use of the at least one type of information to be output when non-matching is determined in the determining.

3. The image display method according to claim 1, further comprising

displaying an alternate image which indicates non-matching in place of an image for which the non-matching is determined in the determining when the at least one type of information to be output is the information on a series of images.

4. The image display method according to claim 1, further comprising

displaying a series of images by skipping an image for which the non-matching is determined in the determining when the at least one type of information to be output is the information on a series of images.

5. The image display method according to claim 1, further comprising

displaying, when the at least one type of information to be output is the information on a series of images and the non-matching is determined in the determining, images in the series of images other than an image for which the non-matching is determined in the determining by deleting the image for which the non-matching is determined.

6. The image display method according to claim 1, wherein

the generating the second information includes generating the second error detection information by including an image included in the diagnosis-report information when the at least one type of information to be output is the diagnosis-report information, and the method further includes

deleting the image included in the diagnosis-report information from the diagnosis-report information and giving a warning/notification on displaying the diagnosis-report information, when the image included in the diagnosis-report information is determined to be non-matching in the determining.

7. The image display method according to claim 1, wherein

the generating the second information includes generating the second error detection information by including an image included in the diagnosis-report information when the at least one type of information to be output is the diagnosis-report information, and the method further comprises

displaying an alternate image indicating non-matching in place of the image included in the diagnosis-report information on displaying the diagnosis-report information, when the image included in the diagnosis-report information is determined to be non-matching in the determining.

8. The image display method according to claim 1, further comprising

notifying that corrupted information exists in the at least one type of information to be output, when non-matching is determined in the determining.

9. The image display method according to claim 1, wherein

the predetermined function is a hash function.

10. An image display apparatus comprising:

a first information generating unit that performs an operation using one of a predetermined function and an operation expression on at least one type of information of identification information including patient information and examination information, information on a series of images acquired by an intra-subject information acquiring apparatus, and diagnosis-report information formulated and updated based on the identification information and the information on a series of images, and generates and adds first error detection information;

a second information generating unit that performs an operation using one of the predetermined function and the operation expression on at least one type of information to be output among the at least one type of information, and generates second error detection information; and

a determining unit that determines whether the first error detection information and the second error detection information match with each other by comparing the first error detection information and the second error detection information.

11. The image display apparatus according to claim 10 further comprising

a use prohibiting unit that prohibits a use of the at least one type of information to be output when non-matching is determined by the determining unit.

12. The image display apparatus according to claim 10 further comprising

an alternate-image-display unit that displays an alternate image which indicates non-matching in place of an image for which the non-matching is determined by the determining unit when the at least one type of information to be output is the information on a series of images.

13. The image display apparatus according to claim 10 further comprising

a skip-display unit that displays a series of images by skipping an image for which the non-matching is determined by the determining unit when the at least one type of information to be output is the information on a series of images.

14. The image display apparatus according to claim 10 wherein

the second information generating unit generates the second error detection information by including an image included in the diagnosis-report information when the at least one type of information to be output is the diagnosis-report information, and the image display apparatus further comprises

a deleting unit that deletes the image included in the diagnosis-report information from the diagnosis-report information and gives a warning/notification on displaying the diagnosis-report information, when the image included in the diagnosis-report information is determined to be non-matching by the determining unit.

15. The image display apparatus according to claim 10 further comprising

a notifying unit that notifies that corrupted information exists in the at least one type of information to be output, when non-matching is determined by the determining unit.

16. The image display apparatus according to claim 10 wherein

the predetermined function is a hash function.
