Abstract
Abstract A new method for detection of lesions and benign and malignant tumors of portions of the human body such as the female breast is described which comprises (a) coating the skin of that portion of the body which is to be evaluated for tumors with a heat sensitive color responsive chemical such as cholesterol (b) heating that portion of the body so coated with penetrating radiation such as diathermy in either the microwave or radio wave frequency and (c) scanning the color coated skin over that portion of the body so treated as to identify by color change that "hot spots" which indicate the location of possible tumors or lesions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
A method for the detection of tumor sites in vivo in human tissue which comprises: (a) coating a portion of the skin tissue surface of the body with a thin film of a heat sensitive liquid which changes color in response to thermal energy input into the tissue (b) heating the entire portion of the body subadjacent to the coated tissue surface uniformly to elevate the normal tissue of the portion of the body heated to a temperature of not more than 104° F and the abnormal tissue of the same portion to a temperature in excess of this temperature so as to cause a color differential in the surface coating and (c) scanning the skin tissue so color coated to identify hot spots thereon as possible sites of underlying tumors
Claim 2
Independent Claim
131 words
A method for the detection of tumor sites in vivo in human tissue which comprises: (a) coating a portion of the skin tissue surface of the body with a thin film of a heat sensitive liquid which changes color in response to thermal energy input into the tissue (b) heating the entire portion of the body subadjacent to the coated tissue surface uniformly to elevate the normal tissue of the portion of the body heated to a temperature of not more than 104° F and the abnormal tissue of the same portion to a temperature in excess of this temperature so as to cause a color differential in the surface coating and (c) scanning the skin tissue so color coated to identify hot spots thereon as possible sites of underlying tumors
Claim 3
Dependent Claim
31 words
A method according to claim 1 wherein the portion of skin tissue is coated with liquid crystals of cholesterol which change color in response to temperature changes in the underlying substrate.
Claim 4
Dependent Claim
19 words
A method according to claim 1 wherein the portion of a body is heated by the application of diathermy.
Claim 5
Dependent Claim
32 words
A method according to claim 3 wherein the portion of the body treated is heated with diathermy for from 10 to 30 minutes at from 50 to 150 watts of input energy.
