Intended Use
The e-Lung software provides reproducible CT values for pulmonary tissue, which is essential for providing quantitative support in the examination of radiological findings. These radiological findings can then be evaluated by the physician in conjunction with a range of ancillary information to form a potential diagnosis or list of likely diagnoses. The e-Lung software package is intended to be a workflow enhancement and for the assessment of CT thoracic datasets. e-Lung can be used to support the physician when examining the pulmonary and thoracic tissue (i.e. lung parenchyma) in CT thoracic datasets. 3D segmentation, volumetric measurements, density evaluations, and reporting tools are combined with a dedicated workflow.
Device Description
Brainomix 360 e-Lung is a software package compliant with the DICOM standard and running on an off-the-shelf physical or virtual server. e-Lung is a CT processing module which operates within the integrated Brainomix 360 platform. Brainomix 360 e-Lung is a stand-alone software device which uses a set of image processing algorithms to perform evaluation (3D segmentation and isolation of sub-compartments, volumetric measurements, and density evaluations), editing, and reporting tools which are combined with a dedicated workflow. e-Lung can be used to support the physician in the examination of radiological findings that may be indicative of chest diseases e.g. when examining the pulmonary and thoracic tissue (i.e. lung parenchyma) in CT thoracic datasets. These radiological findings can then be evaluated by the physician in conjunction with a range of ancillary information to form a potential diagnosis or list of likely diagnoses. e-Lung is designed to analyze pulmonary CT slice data and display analysis results. Each voxel of the scan is measured by Hounsfield units (HU), a measurement of x-ray attenuation that is applied to each volume element in three dimensional space. The HU are utilized to distinguish between air, water, tissue and bone, such distinction is common in the industry. e-Lung provides computed tomography (CT) viewing, and parenchymal density analysis in one application. e-Lung provides quantitative measurements and tabulates quantitative properties. e-Lung focuses on what is visible to the eye and applies volumetric methods that might otherwise be too time consuming to use. The software does not perform any function which cannot be accomplished by a trained user utilizing manual tracing methods; the software does not reconstruct a 3D rendering image of the lung; the intent of the software is to enhance the workflow by saving time and automating potential error prone manual tasks. e-Lung has functions for loading, and saving datasets, and will generate screen displays, computations and aggregate statistics. e-Lung data output may be exported to a CSV, Excel or PDF file.
More Information

Not Found

No
The document explicitly states that a "(non-Al) image processing approach is applied to CT imaging data".

No.
The device is described as a workflow enhancement and a tool to support physicians in evaluating radiological findings and forming diagnoses; it does not directly treat or prevent a disease.

No

The device is described as a "workflow enhancement" tool that provides "quantitative support in the examination of radiological findings" and helps physicians "form a potential diagnosis or list of likely diagnoses." However, it explicitly states, "The software does not perform any function which cannot be accomplished by a trained user utilizing manual tracing methods" and its "intent... is to enhance the workflow by saving time and automating potential error prone manual tasks." This indicates it aids in the diagnostic process but does not independently make a diagnosis, thus it is not a diagnostic device itself.

Yes

The device is explicitly described as a "stand-alone software device" and runs on off-the-shelf hardware. Its function is image processing and analysis of CT data, with no mention of integrated or proprietary hardware components.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze biological samples: IVDs are designed to examine specimens derived from the human body, such as blood, urine, tissue, etc., to provide information about a person's health.
  • This device analyzes medical images: The e-Lung software processes CT thoracic datasets, which are medical images, not biological samples.
  • The intended use is image analysis and workflow enhancement: The description clearly states the software provides quantitative support for evaluating radiological findings from CT scans and enhances the workflow for physicians examining these images. It does not analyze biological markers or substances from a patient sample.

While the software provides quantitative data that can support a physician in forming a diagnosis, the data itself is derived from image analysis, not from an in vitro examination of a biological specimen.

4. Performance Data

4.1 Clinical Study (lung segmentation)

A retrospective study has been carried out to validate the lung segmentation functionality of e-Lung. The study evaluated the accuracy of the e-Lung lung mask generation compared to a ground truth mask generated from the consensus of three experienced US board certified radiologists, who segmented the lungs following their usual standard of care. The similarity between the device lung masks and the ground truth lung masks was evaluated using Dice Similarity Coefficients (DSC), which index the amount of overlap between the two masks. The acceptability criterion for the study was an average DSC across all cases of over 0.95 (defined by the lower bound of the confidence interval).

The dataset for this validation study comprised tomography (CT) chest studies performed in the clinical context of evaluation of lung disease. Cases were selected from two sources: from a research registry held at Boston Medical Center (N=38) and from a commercial database of clinical imaging data (N=62). The number of cases from different scanner manufacturers and models

is shown in Table 1. A range of convolution kernels and acquisition parameters were included in the dataset, including 24 cases acquired with contrast.

The dataset was enriched to ensure a distribution of clinical and demographic variables (e.g. age, gender, race/ethnicity, clinical site, BMI, smoking history and radiological findings) that allows generalizability to the patient population for whom use is intended. The median age was 61 years (inter-quartile range [IQR]: 52.5-70, total range: 23-100). The number of cases in relevant demographic or clinical subgroups is shown in Table 2.

All cases were successfully processed by the device. All cases showed a DSC of above the acceptability criterion (DSC=0.95). The distribution of DSC is shown in Figure 1. The median DSC was 0.978 (IQR: 0.974-0.980). Hence, the study met the acceptability criterion. Performance was consistent for the left and right lungs (left: median DSC=0.976, IQR: 0.972-0.978; right: median DSC=0.979, IQR: 0.976-0.981). Table 3 reports the median (and IQR) DSC for clinically-relevant subgroups, including age, gender, race/ethnicity, BMI, smoking status, radiological findings, hospital location, scanner manufacturer, slice thickness, KvP and contrast. Lung segmentation performance of the device was consistent across all subgroups.
