From Philips Medical Systems;
Philips continues to expand the frontiers of utra high field MRI with the introduction of the new Intera Achieva 3.0T™. Its powerful future-safe platform shares all the advantages of the Achieva family and covers applications throughout the whole body.

The owner of MRI equipment has to ensure that the equipment does fulfill the local requirements.
In some countries, the requirements are more stringent than in others; in other countries, they are nonexistent.
The user in general is unable to check power output, gradient strength, or even field strength. The manufacturer has to cover authorized hardware and software updates after the initial installation and has to give guarantee for the requirements. Specially designed computer programs usually supervise the power output of MRI devices and will not allow or will interrupt any imaging or spectroscopy procedure exceeding those limits considered safe.

From Siemens Medical Systems;
the MAGNETOM Concerto is easy to site and has low life cycle costs due to the permanent magnet. The powerful gradient system with 20 mT/m and a slew rate of 40 T/m/s permits high field applications on a low field open MRI system. The three-sided fully open magnet results in maximum acceptance of claustrophobic or anxious patients and patient access.

Received FDA clearance in 2007.
The MAGNETOM Essenza is designed to combine high system performance with simple installation and power requirements to provide optimal operating costs for limited budgets. The standard system has up to 25 integrated coil elements and 8 independent radio frequency channels. Tim allows the combination of up to 4 different coils that reduce patient and coil repositioning.
The 1.5 Tesla system is designated for a complete range of clinical applications, including neurology, orthopedics, body imaging, angiography, cardiology, breast imaging, oncology and pediatric MRI.

From Siemens Medical Systems; Received FDA clearance in 2013.
The MAGNETOM Prisma is the 3T PowerPack for exploration that offers most demanding clinical and research challenges of today and the future. The latest parallel transmit technology, TimTX TrueShape, enables zooming into specific body regions for enhanced image quality. Furthermore, the Tim 4G integrated coil technology offers remarkable imaging flexibility and supports complex examinations across the whole body.
Onsite upgrades to the MAGNETOM Prisma for customers who have already installed the 3 Tesla MAGNETOM Trio are possible.
