DERMATOLOGY INFORMATION
Among other things, in connection with scanning a lesion on the skin of a subject, the location of the lesion on the subject is automatically determined. The scan and the location are stored on a portable memory device. And the memory device is included in a physical patient record of the subject for later use.
1 . A method comprising
in connection with scanning a lesion on the skin of a subject, automatically determining the location of the lesion on the subject,
storing the scan and the location on a portable memory device, and
including the memory device in a physical patient record of the subject for later use.
2 . The method of claim 1 in which the scanning includes deriving image information corresponding to the lesion.
3 . The method of claim 1 in which the scanning is performed in a manner that reduces the effects of ambient light on image information generated by the scan.
4 . The method of claim 1 in which the location is determined using triangulation.
5 . The method of claim 4 in which the triangulation comprises sending signals between transceivers located in fixed locations relative to the subject and a device located on or near and at a fixed location relative to the subject.
6 . The method of claim 1 in which the portable memory device comprises flash memory.
7 . The method of claim 1 also comprising automatically determining an orientation of the lesion on the subject.
8 . The method of claim 1 also including scanning the lesion again at a later time.
9 . The method of claim 1 in which the lesion comprises a pigmented skin lesion.
10 . The method of claim 8 also comprising
automatically analyzing changes in the lesion represented by the scans of the lesion, and
reporting the changes to a clinician.
11 . The method of claim 1 also including receiving an indication that the lesion is of interest to be later scanned for changes.
12 . The method of claim 11 also including
at a later time identifying to a clinician that the lesion is of interest.
13 . The method of claim 12 in which the identifying comprises a graphical indication on a depiction of the subject's body.
14 . A method comprising in the presence of ambient light having a first set of characteristics, capturing first image information about a lesion on the skin of a subject using a scanner that screens the ambient light from the lesion,
later, in the presence of ambient light having a second set of characteristics, capturing second image information about the lesion using the scanner, and
by machine, analyzing the first image information and the second image information to infer changes in characteristics of the lesion.
15 . The method of claim 14 in which the lesion comprises a pigmented skin lesion.
16 . The method of claim 14 in which the machine analyzes changes in at least one of the size, color, or shape of the lesion.
17 . The method of claim 14 in which the machine analyses changes in the lesion based on multi-spectral properties of the lesion.
18 . The method of claim 14 also including displaying the results of the analysis to a clinician.
19 . The method of claim 14 in which the image information is in an RGB format.
20 . A method comprising
receiving image scans of a pigmented skin lesion of interest on a patient at two different times during which at least one of the color, size, shape, or non-visible multi-spectral characteristics of the pigmented skin lesion may have changed,
by machine performing an analysis of the changes of the pigmented skin lesion, and
reporting the result of the analysis to a clinician through a user interface.
21 . A method comprising
storing on a portable memory device two images of a pigmented skin lesion acquired at two different times,
storing on the portable memory device information about the location of the pigmented skin lesion on the patient,
storing on the portable memory device an indication that that pigmented skin lesion is of interest, and
displaying the images, location information, and indication of interest information to a clinician in connection with a pigmented skin lesion mapping procedure.
