Philips Achieva 1.5 T MRI Machine

Philips Achieva 1.5T XR MRI Machine

The Achieva 1.5T XR by Philips is the only 1.5T MRI Scan Machine that can be upgraded to a 3.0T without swapping the magnet. This allows a clinic or hospital to install an advanced 1.5T system for use today and providing the flexibility to transition into a 3.0T MRI machine in the future. This MRI machine also provides physicians a simple way to transition to 3.0T that makes economic sense. It is more cost effective and efficient than a traditional “forklift” upgrade, which requires system down time, possible construction and the “heavy lifting” associated with room reconfigurations to install a new magnet, power system and gradients.

The Achieva 1.5T XR is equipped with proven X-series technology. It provides high resolution at maximum speed to cover advanced applications. This MRI machine includes all of the advanced tools and features of the Achieva 1.5T (SmartExam, expanded multi-channel SENSE coil portfolio, & FreeWave platform) plus much of the same sophisticated technology of the Acheiva 3.0T X series. 

The Philips Achieva 1.5T A-Series MRI machine offers premium performance for advanced clinical applications such as 3D cardiac imaging and 4D imaging. The Philips Achieva 1.5T A-Series MRI machine also features Philips' SmartExam technology which provides automated scanning, planning and processing for increased productivity.

The Philips Achieva 1.5T SE MRI machine is a low-cost, compact MR imaging system with a patient-friendly design. A scalable RF receiver, parallel imaging, powerful gradients and a large field of view are standard. The Philips Achieva 1.5T SE MRI also features PowerSave, which ensures the machine uses energy only when needed. PowerSave can reduce your energy costs as much as 50% over comparable MRI systems.

The Philips Achieva 1.5T MRI scanner is a very powerful system featuring high intrinsic homogeneity and a lightweight design. FreeWave digital data acquisition platform comes standard with the Philips Achieva 1.5T MRI scanner, providing it access to Philips' latest and most innovative clinical applications.
