ChestGlass [explainer video] is a search engine that finds similar-looking radiographs in a given database.

The similarity is identified by a neural network, which judges both the pathology present as well as other features in the image (such as the location of the pathology, its severity etc.).

When implemented into a PACS/local system/cloud service ChestGlass empowers the user to quickly find retrospective cases with similar radiological appearance. This allows to study the report/final diagnosis/outcome of the patient.

Benefits:

workflow: facilitate the diagnostic process and improve accuracy
teaching: reduce the learning curve for radiology residents
research: find cases that stand out

ChestEye [explainer video] is a fully automatic computer-aided diagnosis (CAD) solution. It currently supports 75 radiological findings, and is able to localize these features on a radiogram in terms of a heatmap. ChestEye is under constant improvement with the goal to generate preliminary reports, that incorporate all the radiologically relevant information present in a chest X-ray radiograph.

The following radiological findings are supported: Linear Atelectasis, Lobar Collapse, Enlarged Heart, Edema, Pleural Effusion, Loculated Effusion, Fissural Thickening, Bullous Emphysema, Pulmonary Emphysema, Subcutaneous Emphysema, Consolidation, Pneumothorax, Tuberculosis, Hypoventilation, Lymphadenopathy, Hypertension, Granuloma, Lymph Node Calficiation, Elevated Diaphragm, Dislocated Mediastinum, Widened Mediastinum, Congestion, Fibrosis, Interstitial Markings, Pleural Adhesion, Hilar Prominence, Mass, Cyst, Pulmonary Cavity, Sarcoidosis, Hernia, Removed Lung, Enlarged Aorta, Goitre, Thymus, Aortic Sclerosis, Respiratory Distress Syndrome, Retrosternal Airspace Obliteration, Pleural Thickening, Pneumomediastinum, Pericardial Effusion, Pleural Plaque, Pneumoperitoneum, CV Catheter RA Placement, CV Catheter SVC Placement, HD Catheter RA Placement, HD Catheter SVC Placement, Catheter Malposition, Intubation, Intubation Malposition, Chest Tube, Sternal Wires, Endovascular Stent, Tracheael Stent, Esophageal Stent, Artificial Heart Valve, Intra Aortic Balloon, Ventricular Assist Device, Nasogastric Tube, Pacemaker, Spinal Implant, Azygos Lobe, Gastric Bubble, Bowel Gas, Barium Swallow, Abnormal Rib, Rib Resection, Spinal Compression Fracture, Spinal Degenerative Changes, Spondylosis, Osteoporosis, Kyphosis, Scoliosis, Ligament Ossification, Spinal Enthesopathy.

Integration with several PACS/DICOM viewers is under way. Cloud and local (non-cloud) deployment is also possible.

ChestEye is applicable to chest X-ray PA and AP images. LAT image support is in development.

Performance: area under curve (AUC) averaged over all the features is 0.91.


QEye is a radiological queue management/patient prioritization solution, which automatically prioritizes potentially unhealthy patients. Currently, queues of images awaiting description by the radiologist can be sorted by exam time, patient name, modality, the imaging site (device), and possibly a priority column, where the priority is currently set by a radiographer. In our proposed solution, the priority column would be provided by our QEye solution (see figure, indicated by a red rectangle).

Problem and Focus

Medical imaging (radiology) is a highly-trained-labour intensive profession. This results in

Shortage of radiologists: everywhere but especially remote areas
Subjectivity: even the best specialists often disagree
Timing: in certain problems (for example, brain stroke) the slowness of human image reading contributes to increased patient mortality
Our deep learning (also known as artificial intelligence, machine learning, artificial neural networks) expertise and data from our partners (hospitals and healthcare companies) allow us to alleviate these problems by reducing routine work and increasing diagnostic accuracy.
