“Without adequate temporal resolution, increased motion can make CT motion unreliable for accurate diagnosis,” Silverman said. “Cardio StillShot is the solution.”
GE Healthcare
Last fall, GE Healthcare launched the Revolution Ascend CT system, which is designed to improve operational efficiencies.

The scanner comes with Effortless Workflow, AI-based software that automates patient positioning and exam settings, saving the technologist time over the course of the exam, said Sonia Sahney, chief marketing officer for molecular imaging and CT at GE Healthcare.
“As we talk about staff shortages and we talk about resource needs, I think this is going be a great step for that,” Sahney said.
The scanner has a 75-centimeter-wide gantry with a lower table position that increases space inside the bore to accommodate larger patients.
Also last fall, GE introduced its new modular Revolution Apex platform, which is scalable and upgradable to meet facilities’ needs.
“You can buy it at a 40-millimeter detector and upgrade it to an 80- or 160-millimeter system, as your clinical needs evolve,” Sahney said. “It gives huge flexibility to buy the technology you need today, but also have the promise of being able to expand that system over the life of the scanner from both hardware and software perspective. We were seeing sites that are keeping our systems much longer than they did 10 years ago.”
The new Revolution Apex platform also offers a gantry speed of 0.23 seconds per rotation, which Sahney says is the fastest in the industry, and 19.5 millisecond effective temporal resolution to freeze cardiac motion.
GE Healthcare is also entering the photon-counting CT arena, and a year after acquiring Prismatic Sensors AB, a Swedish startup specializing in silicon detectors for photon counting CT, it has a clinical evaluation unit in place at the Karolinska Institutet and MedTechLabs. The device has the company's patented Deep Silicon detectors, which has the potential to deliver high spatial resolution without compromising count rate or spectral resolution.
“We've been scanning there and getting some really great results with our deep silicon detector technology,” Sahney said.
iCRco
iCRco recently released a 31-inch, large-bore, 18-kilowatt, portable cone beam CT scanner. The scanner is being deployed, along with X-ray and fluoroscopy systems, in a 16-foot trailer, to create a fully mobile imaging clinic.
The CT scanner comes with an 85-micron voxel size and volume of interest selection to visualize extremely small features, and allows integration of the Anatomage 3D software suite, said Stephen Neushul, president and chief executive officer of iCRco. Advanced artifact rejection and geometric calibration provide clear bone detail and there is new lung nodule tracking capability and early COVID-19 assessment.
