Achieva, Ingenia, Ingenia CX, Ingenia Elition and Ingenia Ambition MR Systems

Philips' Achieva, Ingenia, and related MR systems are advanced diagnostic imaging tools that utilize magnetic resonance principles to generate detailed anatomical and physiological images for clinical diagnosis and procedural guidance. The key innovation in this R11.0 version is the SmartSpeed AI feature, which employs machine learning combined with Compressed-SENSE to significantly accelerate scan times while preserving or enhancing image quality, supported by hardware upgrades like a new GPU for improved reconstruction.

The Philips Achieva, Ingenia, Ingenia CX, Ingenia Elition, and Ingenia Ambition MR Systems are 1.5T and 3.0T magnetic resonance diagnostic devices designed for trained physicians to obtain cross-sectional images, spectroscopic images, and spectra of the head, body, or extremities. These systems operate on the principle of detecting relaxation signals from atomic nuclei within a strong magnetic field when excited by radio signals, subsequently reconstructing these signals into images. They support diagnostic imaging, therapy planning, and guidance for interventional procedures, with users able to customize scan parameters and synchronize acquisitions with physiological cycles. The core technological components such as magnets, coils, and amplifiers remain consistent with previous iterations, while these systems also support various previously cleared pulse sequences and coils. This R11.0 iteration introduces significant software and hardware enhancements, most notably the SmartSpeed AI feature, which integrates machine learning with the previously cleared Compressed-SENSE technology. SmartSpeed AI aims to achieve higher image acquisition accelerations while maintaining or improving image quality, alongside other software updates like SmartSpeed MotionFree, SmartSpeed 3D FreeBreathing, and MR Workspace. Non-clinical performance testing, including pixel-wise comparisons with ground truth data and a reader evaluation study by US board-certified radiologists, demonstrated that SmartSpeed AI provides comparable or better image quality, especially at high acceleration factors and low SNR levels, often with reduced scan times. Hardware upgrades include a new graphical processing unit in the host reconstruction computer for enhanced image reconstruction capabilities and an additional monitor for the operating console.
