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.  #RSNA2021 #RSNA #RSNA21 #POCUS 

Newer enterprise imaging platforms enable storage of all types of non-DICOM data and images. This example from Sectra shows its system can pull up digital pathology slides and available light JPEG images of a suspected skin cancer. Hospitals are looking at enterprise imaging solutions to enable better images and report sharing across various departments beyond radiology and cardiology and into the EMR. #RSNA #pathology #digitalpathology #RSNA21

The first person to even have an MRI performed on the RSNA show floor, while other attendees wait their turn to get a brain scan in the first 15 minutes of the show floor opening on the first day of RSNA 2021. Hyperfine displayed its FDA-cleared Swoop head MRI system, and was among one of the hottest stops of the expo floor this year.

Example of an automated workflow orchestration DICOM worklist on the Sectra enterprise imaging system. The system prevents cherry picking of studies by assigning them to radiologists based on load balancing protocols, the specialties of each reader, the level of read priority and parameters of service level agreements (SLAs) with various hospitals. Workflow orchestration is offered by several vendors as a way to improve radiology workflow and to incorporate rules for priority reads and contract obligations.

Example of an analytics capabilities of the Sectra workflow orchestration system. It can give a clear picture of what radiologists are doing in the system, reads they perform and business metrics for various kinds of exam reads and parameters set in service level agreements (SLAs) with various hospitals.

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's new Definium Tempo fixed, overhead tube suspension digital X-ray system is designed to be a "personal assistant" to radiologists and technologists to improve workflow. This includes a lot of automation to reducing workflow burdens. In patient setup, this includes Auto Positioning, Auto Centering and Auto Tracking, to automate the positioning of system components to maximize overall ergonomic operation for the technologist and improve overall patient experience.

This is the Aspect Imaging Embrace 1T neonate MRI system is a dedicated NICU system. It is self-shielded so it does not require a special imaging room and allows babies to be imaged in the NICU instead of being transported to radiology. The capsule the neonate is placed in is temperature controlled and the noise level is about 65 decibels. It gained FDA in 2017 and also has CE mark. It is installed in 3 U.S. hospitals and one in Israel.

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.

X-ray tube vendor Luxbright is developing a cold-cathode X-ray tube made from zinc-oxide nano crystals. The vendor showed what the crystals look like under a microscope on their phone. They hope to start testing the new tube in 2022. Several companies are working on cold-cathode technology. While working tubes have been made and even commercialized, issue with them appears to be longevity, as they wear out quickly compared to conventional hot-cathode tube technology used for the past 130 years. Luxbright is

An example of a digital pathology microscope slide and a magnified image of the cells beneath it displayed by Sectra. Digital pathology is becoming a bigger part of RSNA as hospitals look at enterprise imaging system to use as a single image repository for all their image-heavy departments.

The Hyperfine Swoop portable MRI system on display at RSNA 2021. The company performed live MRI brain scans on anyone who wanted to be scanned on the show floor. The system is well below 1T and is self shielded so it was safe top operate on the floor. The system has FDA clearance and is designed for use in patient rooms and in the emergency department.

GE Healthcare's new version of its Liver Assist embolization guidance software at RSNA 2021. It uses a rotational angiography sweep to create a cone-beam CT 3D image reconstruction of the liver vessels and the target lesion. The new version also shows the parenchyma (functional area of the anatomy) for a tumor. This can help differentiated the tumor tissue from healthy liver tissue when choosing an embolization site.

This was the first in-person RSNA since 2019 due to the pandemic. Many attendees used the opportunity to get together with distant colleagues and old friends. This was a gathering at the Hyatt after the conference was winding down for the day at RSNA.
