Artificial intelligence enabled cardiac MRI flow analysis from Arterys. Technology like this is helping make cardiac MRI easier and faster to assess.

Dia provides artificial intelligence for cardiac ultrasound to automate ejection fraction and other functions. In the point-of-care ultrasound market the company can help automate cardiac analysis with AI and get consistent results, even with less experienced sonographers. 

A weightless lead protection apron for use by interventionalists in the cath lab made by the Taiwanese vendor Becquerel & Sievert Co., Ltd. It offers more radiation protection than traditional lead aprons, and the weight is supported by a steel tube frame that is on wheels so the operator can move around the room.

Arineta created a dedicated cardiac CT scanner in partnership with GE Healthcare several years ago. With increased interest in CTA with the new chest pain guidelines, the company decided to also start direct sales of these systems for the first time at RSNA in their own booth.

Change Healthcare CVIS echo report with an automated flag that the measurements are abnormal. This technology can help catch issues in automated measurements where there is something noteworthy in the report, or so the clinician can double check how the measurements were made.

GE's Liver Assist embolization guidance technology at RSNA 2021. They showed an enhancement where a virtual map can be created to show how an embolization will effect the tissue downstream to better plan catheter embolization procedures in the cath lab.

Automated transcatheter aortic valve replacement (TAVR) measurements on TeraRecon's advanced visualization system.

The Spectrum Dynamics Veriton SPECT-CT system at RSNA 2021. It with comes in 16, 64 or 128 slice CT configurations. It has 12 SPECT detector robotic arms that automatically move toward the patient and use a sensor to stop a few millimeters from the skin to optimize photon counts and SPECT image quality. It also uses more sensitive CZT digital detectors, which allows either faster scan times, or use of only half the radiotracer dose of analog detector scans. 

Example from Philips spectral CT system showing the conventional cardiac CT and a spectral image that can better enhance iodine contrast to reveal an area of ischemia or infarct in the myocardium. This may eliminate the need for other functional imaging tests.

The Philips AngioCT system, which brings CT imaging into the cath lab.

Novarad demonstrated augmented reality (AR) technology that can fuse cardiac MRI with a live patient on the table and tools for needle guidance for a pericardiocentesis.

Example of flexible 3D printed heart that can be made to the exact size of a patient from their CT scan from Materialise. It can be used to practice procedures and check device sizing. 

Example of life-like 3D printed cardiac and aortic anatomy available from Materialise. The vendor's software is FDA-cleared for use to print anatomy from CT or MRI studies that will be the exact size as the patient's actual anatomy. This can be used for planning and practicing complex surgical or interventional procedures and the model can aid navigation during procedures. 

GE Healthcare showed its new Allia IGS7 angiography system. It was released in 2020 and the first system is now being installed. It features an all new user interface with a set of controls duplicated on three sides of the detector head. A set of controls for the system are also available on a small cart, a taking up the same amount of floor space as an IV stand so the C-arm can be operated from anywhere in the lab. Read more
