Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

Images, or a digital twin mitral valve of a patient, created from cardiac ultrasound that were used to perform a virtual surgical procedure to test how the intervention would impact the patient prior to actually performing the procedure. The right image shows color coding for sheer stresses on the valve leaflets before and after the virtual surgery. The left image shows the model quantitation of leaflet coaptation at peak systole prior to the the virtual surgery.

In the STOIC study, readers classified CT exams as COVID positive, COVID negative or normal. The readers had access to the CT scans using a 3D image visualization web application, allowing scrolling through the entire lung volume in the coronal, sagittal or axial transverse plane. The CT scan shown here has been classified as COVID positive due to the presence of bilateral ground glass opacities and absence of features such as mucoid impaction, bronchiolar nodules, segmental, lobar consolidation.
