Intended Use

The Barco Demetra Analytics Toolkit is a non-invasive skin analysis system. The Barco Demetra Skin Parameter Maps Tool provides maps that show the relative location of blood and pigment. The Barco Demetra Skin Parameter Maps Tool is intended only to complement dermoscopy.

Device Story

Demetra Analytics Toolkit is a software application for analyzing dermoscopic images captured by the Barco Demetra BDEM-01 dermatoscope. It processes multispectral image sets to generate grayscale two-dimensional 'Skin Parameter Maps' visualizing blood and pigment patterns; 'Scatter Contrast Maps' highlight surface contours. Used in professional clinical environments by dermatologists/medical practitioners to complement standard dermoscopy. The software transforms multispectral input data using the Beer-Lambert principle to estimate skin parameters. Clinicians view these maps alongside standard dermoscopic images to assist in evaluating skin lesions, potentially aiding in the assessment of suspicious skin cancer lesions. The device does not provide a diagnosis but serves as an adjunctive visualization tool.

Clinical Evidence

Multiple clinical studies were conducted: 1) Retrospective reader study (n=28) with four dermatologists evaluating subjective ratings of skin parameter maps. 2) Comparative study (SIAscope vs. Demetra) evaluating signal contribution. 3) Prospective study (n=15) correlating maps with pathology H&E images. 4) Validation study (n=15) of skin structures. 5) Retrospective reader study (n=28) validating maps with/without liquid interface. Studies utilized subjective ratings and qualitative analysis to demonstrate clinical utility and safety.

Technological Characteristics

Software-only application; compatible with Barco Demetra BDEM-01 dermatoscope. Sensing principle: multispectral imaging using amber, deep red, green, cyan, blue, royal blue, far red, and red-orange LEDs. Analysis based on Beer-Lambert principle. Output: grayscale 2D maps. Regulatory class II.

Indications for Use

Indicated for use by medical practitioners as a non-invasive skin analysis system to complement dermoscopy by providing maps showing relative blood and pigment locations in skin lesions.

| | Test performed | Result |
| | Software Verification<br>Testing | PASS |
| | Usability Engineering<br>Testing | PASS |
| | Design Validation, which<br>includes integration testing<br>with BDEM-01 device | |
| | The Demetra Analytics Toolkit software has a moderate level of concern. | |
| | Several clinical validation activities have been performed to support safety and<br>effectiveness of the device. This included: | |
| | - A retrospective clinical study "Clinical validation of Demetra Skin Parameter Maps".<br>This retrospective reader study was performed by four board certified<br>dermatologists from different sites in the USA. The selected dataset contains a mix<br>of 28 cases, representing various dermatology conditions for which a dermatologist<br>can use a dermatoscope during evaluation, with a focus on skin lesions suspicious<br>for skin cancer. For each of the cases, all readers provided a subjective rating of<br>the skin parameter maps corresponding to these cases. Statistical analysis was<br>performed on the collected ratings. In addition qualitative feedback from the readers<br>was also collected. | |
| | - A retrospective study "SIAScans vs. Barco Analytics Toolkit" performed by a board<br>certified dermatologist from OHSU Dermatology Clinic, Portland. This study<br>compared performance of the Barco skin parameter maps with performance of the<br>predicate device (Siascope) for a representative set of specific types of cases.<br>Contribution of 'other' signals to the maps (for both Siascope and Barco) was also<br>included in the performance comparison. | |
| | - A prospective clinical study performed by a board certified dermatologist from<br>Washington DC; and a dermato pathologist from Maryland. The study "Correlation<br>of structures visualized in the Skin Parameter Maps with pathology findings" directly<br>compared skin parameter maps with pathology H&E images for collected 15 cases.<br>Subjective rating as well as qualitative case analysis was performed. Statistical<br>analysis was performed on the collected ratings. | |
| | - A clinical study performed by a dermatologist from University Hospital Leuven in<br>Belgium. This study "Validation of skin structures imaged in the Skin Parameter<br>Maps" included 15 cases for which a dermatologist would typically use the skin<br>parameter maps. Subjective rating as well as qualitative case analysis was<br>performed. Statistical analysis was performed on the collected ratings. | |
| | - A clinical study performed at Charité Universitätsmedizin Berlin, Germany; and at a<br>dermatology practice in Oregon, USA. Four observers participated in this<br>retrospective reader study. 28 representative cases were collected from an existing<br>database. Purpose of this study was to validate the skin parameter maps, and more<br>specifically also to validate the device when used with and without liquid interface.<br>All observers provided subjective ratings for every case. Statistical analysis was<br>performed on the collected ratings. | |
| 10.<br>Conclusion | Demetra Analytics Toolkit was found to be as safe, as effective, and performs as well as the legally marketed predicate device, due to the following reasons:<br>a) Device and predicate device have a similar intended use<br>b) The technological characteristics differences from the predicate device do not affect safety or effectiveness<br>c) Bench testing showed that the device has similar characteristics compared to the predicate device and did not reveal new issues of safety and performance. | |
