The indications for use of the product is to remove the cold from the bucky by placing this sheet between patient's breast and the image receptor plate allowing the patient to feel more comfortable and less cold without interfering with image quality.

Device Description

Comfort Cover is a single-use disposable cover placed between the patient's breast and the image receptor plate during mammography. The purpose of this product is to allow the patient to feel more comfortable and less cold during the mammographic examination without interfering with image quality. Comfort Cover will allow for artifact-free images in both Field Digital Mammography (FFDM) and Digital Breast Tomosynthesis (DBT), patient radiation dose is equivalent to that when using no Comfort Cover and the Image quality is equivalent to images exposed without Comfort Cover.

Comfort Cover is designed to fit small and large image receptor plates of all leading mammographic equipments. The product is constructed of a fabric material with a purple printed design and has adhesive backing with a paper liner. Both the material and adhesive backing of the product do not affect imaging.

The product is directly applied wrinkle free to the image receptor plate of the mammographic machine by the adhesive backing exposed by peeling off the liner. After the patient's mammogram, the product is peeled off the image receptor plate and disposed. As the product removes cleanly without leaving behind any residue, the image receptor plate does not need to be cleaned between Comfort Covers nor between patients.

2. Sample size used for the test set and the data provenance
The document does not provide specific sample sizes (e.g., number of covers, images, or participants) for the test sets. It states that "a number of non-clinical performance tests" were completed.

Biocompatibility: Testing was conducted per ISO 10993-5 and ISO 10993-10 on the subject device.
Mechanical Testing: Performed on "both the subject and the predicate devices."
Radiological Studies: Phantom image testing was performed "as per MQSA regulations and with relevant International Electro technical Commission (IEC) standards (62220-1-2:2007 and 61223-3-2)." This implies the use of standardized phantoms, not patient data.
Usability Studies: Included "radiologists, radiology technologists and patients." The number of each group is not specified.

Data provenance (country of origin, retrospective/prospective) is not specified, but given the nature of the tests (lab-based, phantom studies, usability feedback), it is likely all internal data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not provided. For the usability studies, "radiologists" and "radiology technologists" were involved, but their number and specific qualifications (e.g., years of experience) are not detailed. For radiological studies, phantom images were used, implying objective measurements rather than expert human interpretation for ground truth.

4. Adjudication method for the test set
Not applicable or not described. The tests are primarily objective measurements (e.g., passing a specific ISO standard, conforming to ASTM methods, measuring radiation dose, image quality metrics from phantom images). For usability, it simply states that user needs were fulfilled, but no adjudication method for consensus is mentioned.

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
No MRMC study was done, nor is this device related to Artificial Intelligence (AI). The Comfort Cover is a physical accessory for patient comfort during mammography.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is not an algorithm or AI.

7. The type of ground truth used

Biocompatibility: In-vitro and in-vivo (skin irritation/sensitization) test results against ISO standards.
Mechanical Testing: Objective measurements (e.g., ASTM standards, in-house developed test for residue).
Radiological Studies: Objective measurements from phantom images (e.g., presence/absence of artifacts, radiation dose measurements, image quality metrics) compared to baselines (without Comfort Cover) and regulatory/IEC standards.
Usability Studies: User feedback (radiologists, technologists, patients) on comfort and impact on positioning.

8. The sample size for the training set
Not applicable. This device is not an AI/machine learning model and does not have a "training set."

9. How the ground truth for the training set was established
Not applicable.

(7) PERFORMANCE DATA

As part of demonstrating safety and effectiveness of Comfort Cover and in showing substantial equivalence to the predicate device, Precision Dynamics Corporation completed a number of non-clinical performance tests. The Comfort Cover met all the requirements for overall design, biocompatibility, and radiologic safety confirming that the design output meets the design inputs and specifications for the device.

Summary and Conclusions of Biocompatibility Testing

Biocompatibility testing was conducted in accordance with ISO 10993-5, Biological evaluation of medical devices - Part 5: Tests for in vitro Cytotoxicity, and ISO 10993-10, Biological evaluation of medical devices - Part 10: Tests for irritation and skin sensitization.

The subject device passed all of the above tests.

{6}------------------------------------------------

Summary and Conclusions of Comparative Testing

The following mechanical tests were conducted on both the subject and the predicate devices.

Visual and Dimensional examination ●
Thermal Conductivity Test
- This testing was performed per ASTM D5470-12 which is a test method for O measurement of thermal conductivity of materials.
Ink Smear Test
- This test was performed as per ASTM D5264-98 which is a standard test method o for abrasion resistance of printed materials by the Sutherland Rub Tester to test if the ink from the printed graphics smears.
. Peel Adhesion Test
- This test was performed as per ASTM D6252-98 which is a standard test method O for peel adhesion of pressure sensitive label Stocks at a 90° Angle to test the peel adhesion of the device.
Removes Cleanly Test
- o This test was an in-house developed method to test if the product removes cleanly from the mammographic equipment without leaving behind any residue.

The subject device passed all of the above tests.

Summary and Conclusions of Radiological Studies

Phantom image testing was performed as per MQSA regulations and with relevant International Electro technical Commission (IEC) standards (62220-1-2:2007 and 61223-3-2) to verify that,

Comfort Cover will allow for artifact-free images in both FFDM and DBT.
. Patient radiation dose is equivalent to that when using no Comfort Cover.
. Image quality is equivalent to images exposed when using no Comfort Cover.

The subject device passed all of the above tests.

Summary and Conclusions of Usability Studies

Usability studies included radiologists, radiology technologists and patients testing all of the user need requirements. The Comfort Cover fulfilled its design requirements of making the mammography examination more comfortable and did not negatively impact patient positioning.

Summary of Animal Studies

No animal testing was necessary.

Summary of Clinical Studies

No clinical testing was necessary.

{7}------------------------------------------------

8) CONCLUSIONS

The subject device Comfort Cover and the predicate device Bella have the same technological characteristics and intended use.

Both devices have similar design of having rectangular shape with adhesive backing which allows easy application and removal from the image receptor plate and with floral graphics printed on the top of the sheet using FDA approved ink. Both devices are presented as single use, non-sterile and non-compressible.

Both devices remove the cold from the image receptor plate of the mammographic equipment and provide comfort during routine mammographic examinations without affecting image quality. Both devices do not negatively affect patient positioning.

Minor difference in the Comfort Cover material as compared to the predicate device. Bella does not affect safety and effectiveness of the device when used as labeled as shown by safety and efficacy studies. Therefore, Precision Dynamics Corporation believes that Comfort Cover is substantially equivalent to the existing legally marketed predicate device, Bella.
