Managing Low Dosage in Imaging

Dose management continues to gain significance in safe and effective CT imaging and applies equally to the intraoperative setting. IMRIS iCT features a suite of software and hardware applications and protocols that follow the “As Low as Reasonably Achievable” (ALARA) principle to reduce radiation dose to the lowest possible level without compromising image quality. Meeting 100 percent of the American Association of Physicists in Medicine (AAPM) recommendations for dose reduction, the dose controls provide automated and patient specific scan settings for each exam – this is especially important if multiple scans are desired. Among the scan protocols, 68 percent are below the annual natural background radiation of 2.4 mSv. These scans are fully reimbursed imaging CT since it’s compliant with MITA Smart Dose requirements.

In addition, IMRIS  iCT uses a fan beam to limit dose exposure compared to the cone beam of other systems which also have less image contrast and more noise. The IMRIS iCT also features faster rotation speed for quicker scanning further lowering dose exposure for desired images.
