Method and device for evaluating evolution of tumoural lesions

A device for evaluating evolution of tumoural lesions, said device comprising:

• means for receiving a first image of said tumoural lesions, said first image being made at a first time instant;
• means for receiving a second image of said tumoural lesions, said second image being made at a second time instant later than said first time instant;
• means for delineating a border of said tumoural lesions in said first image and said second image;
• means for registration of said tumoural lesions in said first image and said second image;
• means for segmenting said tumoural lesions in said first image and said second image into concentric areas;
• means for quantifying changes of at least one functional parameter between said concentric areas in said first image and respective corresponding concentric areas in said second image;
• means for visualizing said changes in a two-dimensional or three-dimensional model of said tumoural lesions, said means for visualizing comprising means for colouring two-dimensional or three-dimensional concentric shapes in said two-dimensional or three-dimensional model using colours depending on said changes of said at least one functional parameter, wherein said colours comprise:
• a first colour for changes of said at least one functional parameter indicative for regressive tumour lesions or regressive tumour area within one lesion;
• a second colour for changes of said at least one functional parameter indicative for stable tumour lesions or stable tumour area within one lesion;
• and
• a third colour for changes of said at least one functional parameter indicative for progressive tumour lesions or progressive tumour area within one lesion;
• and
• means for determining a first percentage of regressive tumour lesions, a second percentage of stable tumour lesions, and a third percentage of progressive tumour lesions.
