Device Description
Genius Al Detection is a software device intended to identify potential abnormalities in breast tomosynthesis images. Genius Al Detection analyzes each standard mammographic view in a digital breast tomosynthesis examination using deep learning networks. For each detected lesion, Genius Al Detection produces CAD results that include the location of the lesion, an outline of the lesion and a confidence score for that lesion. Genius Al Detection also produces a case score for the entire tomosynthesis exam.
Genius AI Detection packages all CAD findings derived from the corresponding analysis of a tomosynthesis exam into a DICOM Mammography CAD SR object and distributes it for display on DICOM compliant review workstations. The interpreting physician will have access to the CAD findings concurrently to the reading of the tomosynthesis exam. In addition, a combination of peripheral information such as number of marks and case scores may be used on the review workstation to enhance the interpreting physician's workflow by offering a better organization of the patient worklist.

Comparison with Predicate Device:
The Summary of Substantial Equivalence Table above details the similarities and differences between the Genius Al Detection 2.0 device and its predicate device, Genius Al Detection, K201019. Both the proposed and predicate devices use the same technology per 21 CFR 892.2090. Both devices aid in the detection, localization, and characterization of disease specific findings on acquired medical images. The outputs of both devices serve to augment the interpretation of digital breast tomosynthesis exams as a concurrent reading tool. The output is used to inform and assist the interpreting physician, supplementing their clinical expertise and judgment.
Genius AI Detection 2.0 is the follow-up release to the initial launch of the product and provides better performance both in terms of improved specificity and fewer false positives. Algorithm enhancements as well as the expanded training data set were used during development of the 2.0 version. These changes do not raise any issues of safety and effectiveness.
Genius AI Detection 2.0 is compatible with the same imaging systems as the predicate device.
Compatible DBT Systems
The following image types have been tested and are compatible with Genius Al Detection 2.0:
- Hologic standard resolution tomosynthesis slices (1 mm)
- Hologic high resolution tomosynthesis slices (1 mm, Clarity HD)
- Hologic high resolution SmartSlices (6 mm, 3DQuorum)
The CAD marks generated by Genius Al Detection 2.0 for the above image types can also be projected on their corresponding synthesized 2D images, providing that the diagnostic review workstation supports such a feature similar to the predicate device.

Summary of Updates of Genius Al Detection 2.0
Genius Al Detection 2.0 has two changes compared to the previously released product aiming to improve performance, mainly in term of improved specificity, particularly for micro-calcification cancer detection.
The first change is an enlarged cancer data set used to train the deep learning Al models. The cancer database for training and evaluation is enlarged by two-fold. Subsequently, all deep learning Al models have been retrained on the enlarged dataset.
The second change in Genius AI Detection 2.0 is the adoption of a more sophisticated Convolutional Neural Network (CNN) model for the key processing step of calcification cluster classification, replacing the previously used, simpler conventional Artificial Neural Network (ANN) model. The significantly expanded dataset made it possible to train this newly introduced more complex neural network model, and to deliver significantly better performance especially for micro-calcification cancer detection.
In addition, Genius Al Detection 2.0 can now operate directly on processed tomosynthesis reconstructed slices, instead of first having to process the raw projections to a for presentation 3D reconstructed volume as it was the case for the previously approved product. This simplifies processing flow and eliminates the dependency on tomosynthesis raw projection data.
Standalone Performance Testing:
Genius Al Detection 2.0 is a software-only device. The level of concern for the device is determined as Moderate Level of Concern.
Verification testing consisted of software unit testing, software integration testing and software system testing. The verification testing showed that the software application satisfied the software requirements.
Validation testing consisted of determining stand-alone performance of Genius Al Detection 2.0 using a sequestered dataset of digital breast tomosynthesis exams acquired from multiple centers. This dataset was not used for training of Genius Al Detection 2.0 and included tomosynthesis exams of asymptomatic women acquired with Hologic Dimensions 3D Mammography systems.
The sequestered dataset consisted of 764 tomosynthesis exams including 106 biopsy proven cancers, 97 biopsy proven benign cases, 81 recalls and 480 screening negative cases all collected using Hologic's Dimensions 3D Mammography systems. The average patient age was 58 years and collected from multiple sites across the United States. The location for ground truth was determined by a radiology expert using radiology reports, pathology reports, and diagnostic and post-biopsy images when available. The truth was verified by another MQSA-qualified, board-certified radiologist to ensure accuracy and consistency.
To evaluate the performance of Genius Al Detection 2.0 in comparison to its predicate device, a standalone study was conducted on the sequestered dataset described above. Comparison of performance between Genius Al Detection 2.0 and its predicate device was conducted using fROC analysis and by comparing key performance metrics including detection sensitivity, and rate of false positive marks per view. The fROC curves demonstrated significant improvement for Genius Al Detection 2.0 over its predicate device, Genius Al Detection (K201019).
