Abstract

The present invention is a system and method for analyzing medical images and image-derived data. Before the medical image procedure is accomplished, the present invention analyzes and reports on the appropriateness of the proposed procedure based upon known client data. After image and image-derived data is received from an image acquisition device, the present invention validates the data against data validation rules. Once the data is validated, it is analyzed against a knowledgebase to create a proposed diagnosis based on the validated data. The knowledgebase is preferably embodied in a binary cascade system.

Claims

1. A computerized method of analyzing medical cardiographic image-derived data comprising:

a) receiving, at a computerized system, patient data containing data concerning the health and identity of a patient;

b) receiving, at the computerized system, a proposed imaging procedure;

c) analyzing, using a computerized knowledgebase at the computerized system, the proposed imaging procedure in light of the received patient data to determine the appropriateness of the proposed imaging procedure;

d) receiving, at the computerized system, image-derived data;

e) applying, at the computerized system, data validation rules against the image-derived data to determine data accuracy and develop validated data by;

i) applying structural rules to the image-derived data;

ii) applying data comparison rules to the image-derived data; and

iii) applying frequency distribution rules;

f) analyzing, at the computerized system, the validated data against a diagnostic knowledgebase in order to develop higher-level diagnosis information.

2. The computerized method of claim 1, wherein the diagnostic knowledgebase is implemented using a binary cascade.

3. A computerized system for analyzing medical cardiographic image-derived data comprising:

a) means for receiving patient data containing data concerning the health and identity of a patient;

b) means for receiving a proposed imaging procedure;

c) means for analyzing using a computerized knowledgebase the proposed imaging procedure in light of the received patient data to determine the appropriateness of the proposed imaging procedure;

d) means for receiving image-derived data;

e) means for applying data validation rules against the image-derived data to determine data accuracy and develop validated data by;

i) applying structural rules to the image-derived data;

ii) applying data comparison rules to the image-derived data; and

iii) applying frequency distribution rules; and

f) means for analyzing the validated data against a diagnostic knowledgebase in order to develop higher-level diagnosis information.
