Abstract

A method of automatically archiving image information utilizing available xt information is provided. The method includes automatic extraction of textual information from a text frame and converting this information into a text file. This text file is used to construct a text header which is then stored in conjunction with the images to which it relates. Images are stored on a page-by-page basis and the text header is used as a directory address for retrieving the information as well as serving as a message embedded in the image page. A second header may also be created in accordance with another aspect of the invention to identify each image page.

Claims

1. A method of organizing and archiving data developed during an imaging study of a subject, including the steps of:

providing an imaging apparatus for creating images of said subject, said imaging apparatus having a computer associated therewith, said computer having memory storage and a device through which identification information relating to said imaging study may be entered into said imaging apparatus;

generating an analog text frame video signal representative of a text frame image of said identification information;

digitizing said analog text frame video signal to create digital text frame image information;

converting said digital text frame image information into a text file by translating said digital text frame image information into character information;

selecting predetermined character information from said text file; and

storing said character information as header text at a predetermined location in said memory storage.

2. The method of claim 1 including

obtaining images of said subject including employing said computer to store a set of image data associated with each image, and locating said set of image data in memory storage in association with said header text such that said image data is retrieved when said header text is retrieved.

3. The method of claim 1 including

generating a plurality of sets of images relating to one subject and storing a predetermined number of said images in one page of information, and each said page having a predetermined number of horizontal rows of images.

4. The method of claim 3 including

storing said images in said page by initially storing the first line of data of the first image in the first row, and successively storing each line of data of each image in said first row line-by-line until the first row of images is stored, and sequentially storing each row of images line-by-line until all images are stored in said page.

5. The method of claim 3 including

storing said header text as at the first row, first column of said page.

6. The method of claim 5 including

identifying a selected portion of said header text as a directory address used for retrieving said page.

7. The method of claim 6 including

providing a plurality of pages of images relating to a study and storing said pages in memory storage with said header text as said directory address being used to retrieve all pages relating to said study.

8. The method of claim 2 including

providing as said imaging apparatus at least one of computer tomography apparatus, magnetic resonance imaging apparatus, ultrasound imaging apparatus, X-ray imaging apparatus, gamma ray imaging apparatus and digital subtracting angiography apparatus.

9. The method of claim 3 including

selecting a second set of character information from said text file, and storing said second set of character information as a second header text at a predetermined location on each page.

10. The method of claim 9 including

identifying a portion of said second header text as a directory address for retrieving said page from said memory storage.

11. The method of claim 10 including employing said computer in effecting retrieval of said page from memory storage.

12. The method of claim 11 including reconverting said image data associated with each said image on said page to analog video signals for viewing said page.

13. A method of organizing image information representing body portions of a subject during a study of said subject, including the steps of:

creating pages of image information by employing a computer and storing image information representing a plurality of images at predetermined locations on a single page of information such that said page when retrieved from said computer contains a plurality of readable images.

14. The method of claim 13 including

entering into said computer identifying information about said subject at the commencement of said study and capturing said information as a text image,

converting predetermined portions of said text image into character information, and

transferring said character information to each said page of information to appear as identifying text on each said page for said study.

15. A method of archiving groups of image information about a subject obtained from an image generating source for which a text file of identifying information is stored in computer storage associated with said image generating source, including the steps of:

searching said text file retrieving predetermined text image information;

translating said text image into character information which is human readable;

inserting said text image information at a predetermined pixel location on each group of image information.

16. The method of claim 15 including

translating said character information into text image information using a character recognition software program.

17. The method of claim 15 including

obtaining as said image information computer tomography scans.

18. The method of claim 15 including

obtaining as said image information magnetic resonance images.

19. The method of claim 15 including

obtaining as said image information ultrasound images.

20. The method of claim 15 including

obtaining as said image information x-ray images.
