Method and apparatus for providing clinically adaptive compression of imaging data
First Claim
Patent Images
1. A method of compressing clinical image data generated by a device, the method comprising:
- identifying a subregion of interest in the clinical image data;
separating the clinical image into a first portion comprising the subregion of interest and a second portion comprising the clinical image data not in the subregion of interest;
compressing the first portion of the image using a first compression scheme having relatively low information loss and a relatively low compression ratio; and
compressing the second portion of the image using a second compression scheme having relatively higher data information loss and a relatively higher compression ratio.

Abstract
A system and method for clinical adaptive compression of image data is disclosed. Images are examined for contextual data, color/grayscale data, color/grayscale table, interpolated data, temporal redundancy, display mode, and/or other information. One or more subregions of data is identified, simplified, and compressed without degrading the quality of the clinically important information. The less clinically important information is more highly compressed. Redundant and non-essential data may be decimated, and the clinically necessary information is coded and made available for access.

9. A method of compressing clinical image data generated by a device, the method comprising:
-
identifying a subregion of interest in the clinical image data;
separating the clinical image into a first portion comprising the subregion of interest and a second portion comprising the clinical image data not in the subregion of interest;
compressing the second portion of the image using a second compression scheme having relatively higher data information loss and a relatively higher compression ratio;
simplifying the data first portion without reducing the clinically important information in the first data portion;
compressing the simplified data first portion using a first compression scheme having relatively low data information loss and relatively high compression ratio; and
combining the compressed first and second portions of the clinical image data. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

19. A method of compressing clinical image data generated by a device, the method comprising:
-
identifying at least one subregion of clinical interest in the clinical image data;
separating the clinical image into a first portion comprising the subregion of interest and a second portion comprising the clinical image data not in the subregion of interest;
simplifying the first portion of the image using a first scheme that uses various assumptions about the first portion to identify and eliminate redundant data and increase compressibility without affecting clinically important information;
simplifying the second portion of the image using a second scheme using different assumptions than that for the first portion to identify and eliminate redundant data and increase compressibility;
compressing the simplified data of the first portion of the image using a first compression scheme having relatively low information loss; and
compressing the second portion of the image using a second compression scheme having relatively higher information loss.
