ChestView US is a radiological Computer-Assisted Detection (CADe) software device that analyzes frontal and lateral chest radiographs of patients presenting with symptoms (e.g. dyspnea, cough, pain) or suspected for findings related to regions of interest (ROIs) in the lungs, airways, mediastinum/hila and pleural space. The device uses machine learning techniques to identify and produces boxes around the ROIs. The boxes are labeled with one of the following radiographic findings: Nodule, Pleural space abnormality, Mediastinum/Hila abnormality, and Consolidation. ChestView US is intended for use as a concurrent reading aid for radiologists and emergency medicine physicians. It does not replace the role of radiologists and emergency medicine physicians or of other diagnostic testing in the standard of care. ChestView US is for prescription use only and is indicated for adults only.

ChestView US is a radiological Computer-Assisted Detection (CADe) software device intended to analyze frontal and lateral chest radiographs for suspicious regions of interest (ROIs): Nodule, Consolidation, Pleural Space Abnormality and Mediastinum/Hila Abnormality. The nodule ROI category was developed from images with focal nonlinear opacity with a generally spherical shape situated in the pulmonary interstitium. The consolidation ROI category was developed from images with area of increased attenuation of lung parenchyma due to the replacement of air in the alveoli. The pleural space abnormality ROI category was developed from images with: - Pleural Effusion that is an abnormal presence of fluid in the pleural space - Pneumothorax that is an abnormal presence of air or gas in the pleural space that separates the parietal and the visceral pleura The mediastinum/hila abnormality ROI category was developed from images with enlargement of the mediastinum or the hilar region with a deformation of its contours. ChestView US can be deployed on cloud and be connected to several computing platforms and X-ray imaging platforms such as radiographic systems, or PACS. More precisely, ChestView US can be deployed in the cloud connected to a DICOM Source/Destination with a DICOM Viewer, i.e. a PACS. After the acquisition of the radiographs on the patient and their storage in the DICOM Source, the radiographs are automatically received by ChestView US from the user's DICOM Source through intermediate DICOM node(s) (for example, a specific Gateway, or a dedicated API). The DICOM Source can be the user's image storage system (for example, the Picture Archiving and Communication System, or PACS), or other radiological equipment (for example X-ray systems). Once received by ChestView US, the radiographs are automatically processed by the AI algorithm to identify regions of interest. Based on the processing result, ChestView US generates result files in DICOM format. These result files consist of annotated images with boxes drawn around the regions of interest on a copy of all images (as an overlay). ChestView US does not alter the original images, nor does it change the order of original images or delete any image from the DICOM Source. Once available, the result files are sent by ChestView US to the DICOM Destination through the same intermediate DICOM node(s). Similar to the DICOM Source, the DICOM Destination can be the user's image storage system (for example, the Picture Archiving and Communication System, or PACS), or other radiological equipment (for example X-ray systems). The DICOM Source and the DICOM Destination are not necessarily identical. The DICOM Destination can be used to visualize the result files provided by ChestView US or to transfer the results to another DICOM host for visualization. The users are them as a concurrent reading aid to provide their diagnosis. For each exam analyzed by ChestView US, a DICOM Secondary Capture is generated. If any ROI is detected by ChestView US, the output DICOM image includes a copy of the original images of the study and the following information: - Above the images, a header with the text "CHESTVIEW ROI" and the list of the findings detected in the image. - Around the ROI(s), a bounding box with a solid or dotted line depending on the confidence of the algorithm and the type of ROI written above the box: - Dotted-line Bounding Box: Identified region of interest when the confidence degree of the AI algorithm associated with the possible finding is above "high-sensitivity operating point" and below "high specificity operating point" displayed as a dotted bounding box around the area of interest. - Solid-line Bounding Box: Identified region of interest when the confidence degree of the AI algorithm associated with the finding is above "high-specificity operating point" displayed as a solid bounding box around the area of interest. - Below the images, a footer with: - The scope of ChestView US to allow the user to always have available the list of ROI type that are in the indications for use of the device and avoid any risk of confusion or misinterpretation of the types of ROI detected by ChestView US. - The total number of regions of interest identified by ChestView US on the exam (sum of solid-line and dotted-line bounding boxes) If no ROI is detected by ChestView US, the output DICOM image includes a copy of the original images of the study and the text "NO CHESTVIEW ROI" with the scope of ChestView US to allow the user to always have available the list of ROI type that are in the indications for use of the device and avoid any risk of confusion or misinterpretation of the types of ROI detected by ChestView US. Finally, if the processing of the exam by ChestView US is not possible because it is outside the indications for use of the device or some information is missing to allow the processing, the output DICOM image includes a copy of the original images of the study and, in a header, the text "OUT OF SCOPE" and a caution message explaining the reason why no result was provided by the device.

It should not be used instead of full patient evaluation or solely relied upon to make or confirm a diagnosis. The software device is to be used by healthcare professionals trained in radiology.

BoneMetrics US is intended to analyze radiographs using machine learning techniques to provide fully automated measurements of cobb angles during the review of frontal spine radiographs. BoneMetrics US can be deployed on cloud and be connected to several computing platforms and X-ray imaging platforms such as radiographic systems, or PACS. More precisely, BoneMetrics US can be deployed in the cloud connected to a DICOM Source/Destination with a DICOM Viewer, i.e. a PACS. After the acquisition of the radiographs on the patient and their storage in the DICOM Source, the radiographs are automatically received by BoneMetrics US from the user's DICOM Source through intermediate DICOM node(s) (for example, a specific Gateway, or a dedicated API). The DICOM Source can be the user's image storage system (for example, the Picture Archiving and Communication System, or PACS), or other radiological equipment (for example X-ray systems). Once received by BoneMetrics US, the radiographs are automatically processed by the Al algorithm without requiring any user inputs. The algorithm identifies the keypoints corresponding to the corners of all the vertebras that are seen on the images and calculates all possible angles between vertebras. Only Cobb Angles that are above 7° are retained. Based on the processing result, BoneMetrics US generates result files in DICOM format. These result files consist of annotated images with the measurements plotted on a copy of all images (as an overlay) and angle values displayed in degrees. BoneMetrics US does not alter the original images, nor does it change the order of original images or delete any image from the DICOM Source. Once available, the result files are sent by BoneMetrics US to the DICOM Destination through the same intermediate DICOM node(s). Similar to the DICOM Source, the DICOM Destination can be the user's image storage system (for example, the Picture Archiving and Communication System, or PACS), or other radiological equipment (for example X-ray systems). The DICOM Source and the DICOM Destination are not necessarily identical. The DICOM Destination can be used to visualize the result files provided by BoneMetrics US or to transfer the results to another DICOM host for visualization. The users are then able to use them as a concurrent reading aid to provide their diagnosis. The displayed result for the BoneMetrics US is a summary in a unique Secondary Capture with the following information: The image with the angle(s) in degree drawn as an overlay (if any), A table with the angle(s) measurement(s) and value(s) in degree (if any), At the bottom, the "Gleamer" logo and the "BoneMetrics" mention.

BoneView is intended to analyze radiographs using machine learning techniques to identify and highlight fractures during the review of radiographs. BoneView can be deployed on-premises or on cloud and be connected to several computing platforms and X-ray imaging platforms such as X-ray radiographic systems, or PACS. More precisely, BoneView can be deployed: - In the cloud with a PACS as the DICOM Source - . On-premises with a PACS as the DICOM Source - On-premises with an X-ray system as the DICOM Source After the acquisition of the radiographs on the patient and their storage in the DICOM Source, the radiographs are automatically received by BoneView from the user's DICOM Source through an intermediate DICOM node (for example, a specific Gateway, or a dedicated API).

The DICOM Destination can be used to visualize the result files provided by BoneView or to transfer the results to another DICOM host for visualization. The users are then able to use them as a concurrent reading aid to provide their diagnosis. The general layout of images processed by BoneView is comprising: (1) The "summary table" – it is a first image that is derived from the detected regions of interest in the following result images and that displays the results of the overall study along with the Gleamer – BoneView logo. This summary can be configured to be present or not. (2) The result images – they are provided for all the images that were processed by BoneView and contain: - . Around the Regions of Interest (if any), a rectangle with a solid or dotted line depending on the confidence of the algorithm (see below) - . Around the entire image, a white frame showing that the images were processed by BoneView - . Below the image: - o The Gleamer BoneView logo - o The number of Regions of interest that are displayed in the result image - (if any) The caution message if it was identified that the image was not part of o the indication for use of BoneView The training of BoneView was performed on a training dataset of 44,649 radiographs, representing 151,096 images (52.4% of males, with age: range [0 – 109]; mean 42.4 +/- 24.6) for all anatomical areas of interest in the Indications for Use and from various manufacturers. BoneView has been designed to solve the problem of missed fractures including subtle fractures, and thus detects fractures with a high sensitivity. In this regard, the display of findings is triggered by a "high-sensitivity operating point" (DOUBT FRACT) that will enable the display of a dotted-line bounding box around the region of interest. Additionally, the users need to be confident that when BoneView identifies a fracture, it is actually a fracture. In this regard, an additional information is introduced to the user with a "high-specificity operating point" (FRACT). These two operating points are implemented in the User Interface as follow: - Dotted-line Bounding Box: suspicious area / subtle fracture (when the level of . confidence of the Al algorithm associated with the finding is above "high-sensitivity operating point" and below "high-specificity operating point") displayed as a dotted bounding box around the area of interest - . Solid-line Bounding Box: definite or unequivocal fractures (when the level of confidence of the AI algorithm associated with the finding is above "high-specificity operating point") displayed as a solid bounding box around the area of interest BoneView can provide 4 levels of results: - . FRACT: BoneView identified at least one solid-line bounding box on the result images, - . DOUBT FRACT: BoneView did not identify any solid-line bounding box on the result images but it identified at least one dotted-line bounding box in the result images, - . NO FRACT: BoneView did not identify any bounding box at all in the result images, - NOT AVAILABLE: BoneView identified that the original images are out of its Indications for Use
