The description focuses on traditional image processing algorithms (segmentation, registration, thresholding, classification) and does not mention AI or ML. The testing described is also focused on verifying these algorithmic functions against predicate devices and existing datasets, not on training or evaluating an AI/ML model.
No
The device is a software for image post-processing and analysis to support diagnosis, not for direct treatment or therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that the software "can be used to support the diagnosis and documentation of pulmonary tissue images." This indicates that its purpose is to aid in the diagnostic process.
Yes
The device description explicitly states that the Imbio CT Lung Density Analysis Software is a "set of image post-processing algorithms" and a "command-line software application" that analyzes existing DICOM datasets. It does not include or interface directly with any hardware for data collection or processing.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood and tissue donations, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or a congenital abnormality, or to determine the safety and compatibility with potential recipients, or to monitor therapeutic measures.
- Device Function: The Imbio CT Lung Density Analysis Software processes images of the lungs obtained from a CT scanner. It does not analyze specimens (like blood, tissue, or other bodily fluids) derived from the human body.
- Intended Use: The intended use is to provide quantitative support for diagnosis and follow-up examinations by analyzing CT images. This is image analysis, not in vitro testing of biological samples.
Therefore, while it is a medical device used to aid in diagnosis, it falls under the category of medical image analysis software, not an In Vitro Diagnostic device.

Device Description
The Imbio CT Lung Density Analysis Software (Imbio LDA) is a set of image post-processing algorithms that perform image segmentation, registration, thresholding, and classification on CT images of human lungs.
The algorithms within the Imbio CT Lung Density Analysis Software are combined into a single command-line executable program that may be run directly from the command-line or through scripting. The Imbio CT Lung Density Analysis Software program performs segmentation, then registration, then thresholding and classification. The program reads in DICOM datasets, processes the data, then writes output DICOM files to a specified directory.
The Imbio CT Lung Density Analysis Software is a command-line software application that analyzes DICOM CT lung image datasets and generates reports and DICOM output that show the lungs segmented and overlaid with color-codings representing the results of its thresholding and classification rules. It has simple file management functions for input and output, and separate modules that implement the CT image-processing algorithms. Imbio CT Lung Density Analysis Software does not interface directly with any CT or data collection equipment; instead the software imports data files previously generated by such equipment.

The following testing was conducted on Imbio CT Lung Density Analysis Software by analyzing CT datasets available upon request from the COPDGene study (www.copdgene.org) and the DIR-Lab (www.dir- lab.com): Direct predicate comparison for scan processing completion, segmentation, and thresholding. This was done to verify that the software functions according to its specifications and to support substantial equivalence. Software verification and validation testing for each requirement specification. Software verification and validation testing for each algorithmic function. Software verification and validation testing at the unit, integration, and system level.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Testing: Direct predicate comparison for scan processing completion, segmentation, and thresholding using CT datasets from COPDGene study and DIR-Lab. Software verification and validation testing for each requirement specification, algorithmic function, and at the unit, integration, and system level.
Clinical Testing: Not considered necessary, as the technology is not new and the indications for use are equivalent to the predicate device. Substantial equivalence is supported by non-clinical testing.
Conclusion: The results of testing show the Imbio CT Lung Density Analysis Software to be substantially equivalent to the predicate device. It has the same technological characteristics, similar intended use, same general operating principle, and same technology. Testing shows similar results are produced. Differences do not raise questions regarding safety and effectiveness.

| 510(k) Summary (As required by Section 21 CFR 807.92(c)) | | |
| Summary of Technical Comparisons | Similarities:
Both the predicate device and the Imbio CT Lung Density Analysis Software are software applications that import CT DICOM data files, analyze them, and produce reports with quantitative and graphical results. The functionality of Imbio CT Lung Density Analysis Software is substantially equivalent to the predicate device. Direct quantitative comparisons using the same CT lung scans yielded similar results.
Differences:
The Imbio Lung Density Analysis Software provides a command-line interface, while the predicate device provides a graphic user interface. The Imbio Lung Density Analysis Software provides automated registration of the Inspiration / Expiration image pairs, while this registration is manual (i.e., visually performed by the radiologist) with the predicate device. The predicate device provides an interactive visualization of the reconstructed three-dimensional volume, low-density cluster analysis, and an airway report. These features are not part of the Imbio CT Lung Density Analysis Software. These differences do not affect the efficacy and safety of the Imbio CT Lung Density Analysis Software. | |
| Non-Clinical Testing | The following testing was conducted on Imbio CT Lung Density Analysis Software by analyzing CT datasets available upon request from the COPDGene study (www.copdgene.org) and the DIR-Lab (www.dir- lab.com): Direct predicate comparison for scan processing completion, segmentation, and thresholding. This was done to verify that the software functions according to its specifications and to support substantial equivalence. Software verification and validation testing for each requirement specification. Software verification and validation testing for each algorithmic function. Software verification and validation testing at the unit, integration, and system level The following quality assurance measures were applied during software development: Software Development Life Cycle Software Risk Assessment. Risk Assessment of Off-the-Shelf (OTS) Software. Software Configuration Management and Version Control. Software issue tracking and resolution | |
| 510(k) Summary (As required by Section 21 CFR 807.92(c)) | | |
| Design Validation | Design validation was performed using the Imbio CT Lung Density Analysis
Software in actual and simulated use settings. The results support
substantial equivalence to the predicate device and demonstrate that the
Imbio CT Lung Density Analysis Software is safe for its intended use. | |
| Clinical Testing | This technology is not new, therefore a clinical study was not considered
necessary prior to release. Additionally, there was no clinical testing
required to support the medical device as the indications for use is
equivalent to the predicate device. The substantial equivalence of the
device is supported by the non-clinical testing. | |
| Conclusion: | We conclude that the results of testing show the Imbio CT Lung Density
Analysis Software to be substantially equivalent to the predicate device.
The Imbio CT Lung Density Analysis Software has the same technological
characteristics as the predicate device in that it has a similar intended use,
same general operating principle, and same technology. The specific
details of the predicate device may vary from those of Imbio CT Lung
Density Analysis Software, but testing shows that similar results are
produced.
It has been shown in this 510(k) submission that the differences between
the Imbio CT Lung Density Analysis Software and the VIDA PW2
(K0832277) do not raise any questions regarding safety and effectiveness.
The Imbio CT Lung Density Analysis Software, as designed and
manufactured, is substantially equivalent to, and as safe and effective as,
the referenced predicate device. | |
