#### C.8.12.13 Dermoscopic Image Module

C.8.12.13-1 specifies the Attributes that describe dermoscopic images.

Table C.8.12.13-1. Dermoscopic Image Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Recognizable Visual Features | (0028,0302) | 1 | Indicates whether or not the image contains sufficiently recognizable visual features to allow the image or a reconstruction from a set of images to identify the Patient. Enumerated Values: YES NO The value of Recognizable Visual Features (0028,0302) shall be YES if the image contains the patient's fingerprints
Light Source Polarization | (0016,1001) | 2 | Polarization of the dermoscope light source. Enumerated Values: POLARIZED NON_POLARIZED
Emitter Color Temperature | (0016,1002) | 2 | Color temperature of dermoscope light source in Kelvin.
Contact Method | (0016,1003) | 2 | Whether or not the image was acquired with the dermoscope in direct contact with the skin. Enumerated Values: CONTACT NON_CONTACT
Immersion Media | (0016,1004) | 2C | The interface between the dermoscope and the skin surface for images acquired with contact dermoscopy. Enumerated Values: ULTRASOUND_GEL ALCOHOL WATER MINERAL_OIL PLASTIC_CAP Required if Contact Method (0016,1003) is CONTACT
Optical Magnification Factor | (0016,1005) | 2 | Optical magnification factor when the image was acquired. Optical magnification is achieved using the optics of the dermoscope. The number indicates the magnification factor in times (X). The size of an object (e.g., a skin lesion) would appear on the sensor n times larger than the object when imaged with a dermoscope using n X optical magnification.
Partial View | (0028,1350) | 3 | Indicates whether this image is a partial view, that is a subset of a single view of a skin lesion. Enumerated Values: YES NO If this Attribute is absent, then the image may or may not be a partial view.
Partial View Description | (0028,1351) | 3 | Free text description of the portion of the skin lesion captured in a partial view image.
Tracking ID | (0062,0020) | 1C | A text label used for tracking a finding or feature, potentially across multiple reporting objects, over time. This label shall be unique within the domain in which it is used. Required if Tracking UID (0062,0021) is present. ### Note This Attribute allows linkage to Content Items in SR instances with observation context (112039, DCM, "Tracking Identifier") having the same value.
Tracking UID | (0062,0021) | 1C | A unique identifier used for tracking a finding or feature, potentially across multiple reporting objects, over time. Required if Tracking ID (0062,0020) is present. ### Note This Attribute allows linkage to Content Items in SR instances with observation context (112040, DCM, "Tracking Unique Identifier") having the same value.
