Abstract

A medical diagnostic system comprises a monitoring device juxtaposable to a patient for collecting individualized medical data about the patient'"'"'s condition, and a digitizer operatively connected to the monitoring device for digitizing the data. A computer is operatively connected to the digitizer and a memory which stores medical data for a multiplicity of previously diagnosed medical conditions. The computer is operated to compare digitized data about the patient'"'"'s condition with the data stored in the memory and for deriving a diagnosis as to the patient'"'"'s condition. The computer is connected to an ooutput device, e.g., a printer, for communicating the derived diagnosis to a user.

Claims

1. A medical diagnostic method comprising the steps of:

providing a video camera;

aiming said video camera at a skin surface of a patient;

operating said video camera to generate a digitized video signal encoding an image of the skin surface of the patient;

automatically analyzing said video signal to derive digitized data pertaining to visually detectable characteristics of the skin surface of the patient;

automatically comparing the digitized data with data stored in an electronic memory to derive a diagnosis as to a skin condition of the patient; and

communicating the derived diagnosis to a user.

2. The method defined in claim 1 wherein said step of automatically analyzing includes the step of automatically deriving a parameter abstracting information about the image.

3. The method defined in claim 2 wherein said step of analyzing includes the step of automatically determining a percentage of skin covered by an abnormal condition.

4. The method defined in claim 2 wherein said step of analyzing includes the step of determining a range of sizes of individual ulcers on the skin surface of the patient.

5. The method defined in claim 2 wherein said step of analyzing includes the step of determining a range of color variation of the skin surface of the patient.

6. The method defined in claim 1, further comprising the steps of:

measuring a predetermined physiological parameter of the patient to determine a value for said parameter;

automatically digitizing the determined value of the physiological parameter,

said step of comparing including the step of automatically comparing the digitized value of the physiological parameter with data stored in the electronic memory.

7. The method defined in claim 6 wherein said step of measuring includes the step of monitoring a physiological paratmer taken from the group including temperature, blood pressure, pulmonary function, and cardiac function.

8. The method defined in claim 1 wherein said step of comparing includes the step of operating a computer to compare the digitized data with data stored in said memory, further comprising the step of feeding to said computer information pertaining to medical history, past diseases and genetic predispositions of the patient.

9. A medical diagnostic method comprising the steps of:

scanning the patient to generate a digitized electrical signal encoding an image of an organic part of the patient;

automatically analyzing said video signal to derive digitized data pertaining to structural characteristics of the organic part of the patient;

measuring a predetermined physiological parameter of the patient to determine a value for said parameter;

automatically digitizing the determined value of the physiological parameter;

automatically comparing the digitized data and the digitized value of the physiological parameter with data stored in an electronic memory to derive a diagnosis as to the patient'"'"'s condition; and

communicating the derived diagnosis to a user,

said step of scanning including the steps of aiming a video camera at a skin surface of the patient and operating said video camera to generate in electrically encoded form a visually readable image of the skin surface of the patient, said electrical signal being a video signal, said visually readable image being encoded in said video signal.

10. The method defined in claim 9 wherein said step of measuring includes the step of monitoring a physiological paratmer taken from the group including temperature, blood pressure, pulmonary function, and cardiac function.

11. The method defined in claim 9 wherein said step of comparing includes the step of operating a computer to compare the digitized data and the digitized value of the physiological parameter with data stored in said memory, further comprising the step of feeding to said computer information pertaining to medical history, past diseases and genetic predispositions of the patient.

12. A medical diagnostic system comprising:

scanning means juxtaposable to a patient for collecting image type data about the patient and for generating a first digitized electrical signal encoding said image type data;

monitoring means juxtaposable to the patient for collecting data about a physiological characteristic of the patient and for generating a second digitized electrical signal encoding said data about said physiological characteristic;

memory means for storing medical data for a multiplicity of previously diagnosed medical conditions;

computing means operatively connected to said memory means, said scanning means, and said monitoring means for comparing data encoded in said first electrical signal and in said second electrical signal with the data stored in said memory means and for deriving a diagnosis as to the patient'"'"'s condition; and

output means operatively connected to said computing means for communicating the derived diagnosis to a user.

13. The system defined in claim 12 wherein said scanning means includes a device taken from the group consisting of an NMI apparatus, a CAT scanner, an X-ray machine, an ultrasonography apparatus, and a video camera.

14. The system defined in claim 12 wherein said monitoring means includes a device taken from the group including an electronic thermometer, an electronic blood pressure gauge, a pulmonary function apparatus, a doppler study apparatus, an EEG machine, an EKG machine, and an EMG machine.
