The SIAscope is a non-invasive skin analysis system, which provides color bitmaps called 'SIAscans' that show the relative location of blood, collagen and pigment.
CAUTION : This device should only be used to scan the patient's skin.

The SIAscope is a quick, non-invasive device for imaging skin conditions. It uses a technique known as 'Spectrophotometric Intracutaneous Analysis' (SIAscopy) to identify and display graphically the separate components of the skin. SIAscopy uses a digital camera and light (both visible and near-infrared) to investigate the skin's interior structure.
The SlAscope operates by illuminating the skin with LEDs and measuring the intensity of remitted light. The intensity of the illumination is similar to the emission from a typical hand held torch or remote control unit.

Here's the analysis of the provided text regarding the SIAscope V device, focusing on acceptance criteria and supporting studies:

The provided text is a 510(k) Summary for the SIAscope V, and it primarily focuses on establishing substantial equivalence to a predicate device (SIAscope II). It does not contain information about specific acceptance criteria, a standalone study proving the device meets acceptance criteria, sample sizes for test or training sets, ground truth establishment methods, or Multi-Reader Multi-Case (MRMC) comparative effectiveness studies.

The document states that "Where alterations have been make this have been design to improve the imaging performance, reliability and safety of the device over and above the predicate device." However, no specific performance metrics or studies are provided to substantiate these improvements, nor are there acceptance criteria defined.

Therefore, many of the requested sections will be marked as "Not Available in Document."

Acceptance Criteria and Study Information for SIAscope V

1. A table of acceptance criteria and the reported device performance

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

• Sample Size for Test Set: Not Available in Document
• Data Provenance: Not Available in Document (The document focuses on device design and comparison, not clinical study data).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

• Number of Experts: Not Available in Document
• Qualifications of Experts: Not Available in Document

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

• Adjudication Method: Not Available in Document

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• MRMC Study Done?: No, an MRMC study is not mentioned or described in the document. The SIAscope is described as providing "SIAscans" to show relative location of blood, collagen, and pigment, implying it's an imaging tool for analysis, not an AI-assisted diagnostic tool for human readers in the context usually implied by MRMC studies of AI.
• Effect Size of Improvement: Not Applicable / Not Available in Document.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

• Standalone Study Done?: Not Available in Document. The document mentions "software algorithms" for SIAscopy, but it does not describe a standalone performance study. The device provides "color bitmaps" or a "synthesized image" for analysis, suggesting it's an image acquisition and processing system rather than an algorithm producing a diagnostic output without human interpretation.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

• Type of Ground Truth: Not Available in Document. As no study is described to validate the device's diagnostic performance, no ground truth is mentioned. The device's output is "relative location of blood, collagen and pigment," which is an imaging characteristic rather than a definitive diagnosis requiring a ground truth like pathology.

8. The sample size for the training set

• Sample Size for Training Set: Not Applicable / Not Available in Document. The document states that the "software algorithms and theory of SIAscopy is the same as found in the predicate device." This suggests the algorithms were developed prior to this submission and are not described as being subject to a new training phase for the SIAscope V.

9. How the ground truth for the training set was established

• Ground Truth Establishment for Training Set: Not Applicable / Not Available in Document. As noted above, the algorithms are stated to be the same as the predicate, and no training data or ground truth establishment is described for this submission.
