A woman in her 50s, complaining of paroxysmal chest pain for one month and presenting with left ventricular hypertrophy, was referred to CT for triple-rule-out after a vasovagal episode related to stress.
Thanks to the 160 mm coverage, this exam was performed with two axial volumes for optimal visualization of pulmonary arteries, thoracic aorta and motion free coronaries. The new generation of iterative reconstruction ASiR-V delivers diagnostic image quality at half a milliSievert.
Revolution CT puts the next generation of iterative reconstruction, ASiR-V, up to 160 mm of multivolume axial scanning and up to 80 mm collimation for helical scanning in your hands, helping you acquire high-definition images at lower doses.
ASiR-V1 was designed to deliver reduced noise levels and improve low-contrast detectability so you can routinely reduce dose up to 82% relative to FBP at the same image quality3 for patients of all ages.
Revolution CT introduces the groundbreaking Gemstone Clarity Detector that gives you 160 mm whole organ coverage with best-in-class spatial resolution. The focally-aligned, miniaturized detector modules and 3D collimator are designed to reduce electronic noise by 25% which may improve image quality and reduce artifacts in low signal conditions, for example in large patients or when scanning at low kV and mA.
Revolution CT features also the latest Smart Dose technologies designed to help you acquire high quality images using lower doses of radiation. Smart Dose technologies may help you make a more accurate diagnosis and lower exposure for patients across routine and advanced exams, including dynamic acquisitions for perfusion and 4D studies. Smart Dose technologies include kV Assist that helps you select the right settings for the patient being scanned. It recommends tube voltage and current to achieve the lowest dose while meeting your image quality goals.
Finally, Revolution CT allows 70 kV scanning so you can develop low-dose protocols, which are especially suitable for pediatric imaging.
