“The algorithms provide several different complementary measurements, looking at ground glass opacities and consolidations, along with high-opacity abnormalities across the lung lobes that correlate to severe COVID-19 symptoms,” Shen said.
The algorithms have been trained on CT scans of COVID-specific patients from around the globe.

Just before last year’s RSNA, Siemens Healthineers received FDA clearance for the premium SOMATOM X.cite CT scanner. The scanner has an 82-centimeter gantry bore, which is the largest diagnostic CT bore in the industry, with applications for bariatric imaging, said Matthew Dedman, senior marketing director for the CT business at Siemens Healthineers North America.
The scanner utilizes the myExam Companion intelligent user interface concept, a tool that Dedman said acts as a GPS for the CT technologist, guiding them through how to set up and select the proper exam protocols for each patient.
“Can this patient hold their breath? Is this a screening exam? Does the patient have metal artifacts?” Dedman said. “Based on the response to these questions, the scanner will then automatically navigate through a decision tree and arrive at the proper protocol for that patient, and bring in and apply the proper scanning techniques that are appropriate for that patient. This makes the technologist more efficient and allows them to spend less time setting up exams and more time with the patient.”
This past August, the company received FDA clearance for its mobile SOMATOM On.site CT scanner
This is the first entry into the mobile CT market for Siemens Healthineers. The most common use is for head imaging in the neuro ICU, though Dedman believes there’s the potential for the technology to be used in stroke imaging.
“Without a mobile CT product, transporting the patient from the ICU to radiology requires personnel and creates an increased risk of complications, and the ICU is left understaffed,” Dedman said. “The radiology department also has to block the scanner out for up to an hour.”
The product has the same detector technology, X-ray tube technology and reconstruction software as other Siemens Healthineers CT scanners. The gantry of the system is self-shielded and lead lined, which dramatically reduces the amount of X-ray scatter, Dedman said.
“There’s only one other manufacturer in this space,” Dedman said. The current products have limitations, including degraded image quality, workflow challenges and challenges with radiation scatter in the room. We believe we’ve overcome these.”
