Methods for Assessing Erythema

The method of any of the preceding claims wherein the erythema value is correlated to the intensity of erythema and/or the gradient between two or more erythema values is correlated to the development of erythema.

The method of any of the preceding claims, wherein the light reflectance is measured in a color space other than the L*a*b* color space, and the L* value and the a* value and the b* value according to the L*a*b* color space are obtained by converting the light reflectance values of said measurement into the corresponding values of the L*a*b* color space.

The method of any of the preceding claims, wherein the erythema value is compared to a reference erythema value.

The method of any of the preceding claims, wherein the light reflectance of a skin or mucosal area of a subject is measured by obtaining an image of said area.

The method of any preceding claim wherein the mobile device is linked to a clinical service system.

The method of any preceding claim wherein the mobile device is a tablet or smartphone.

The method of any preceding claim wherein the mobile device is linked to a cancer irradiation machine.

The method of any of the preceding claims wherein the measured area is a gross area comprising one or more segment areas and wherein any of the calculated values is calculated for each segment area.

The method of any of the preceding claims, wherein the measuring step(s) and/or the obtaining step(s) and/or the calculating step(s) or any combinations thereof, especially all steps, are performed using a mobile device, such as a cell phone or smart phone or tablet.

The method of any of the preceding claims, further comprising obtaining the measured light reflectance, preferably by transmission over a network.

The method of any of the preceding claims, wherein the obtaining step(s) and/or the calculating step(s), especially all of said steps, are performed using web-based or cloud-based processes.
