Indications for Use

Vantage Orian 1.5T systems are indicated for use as a diagnostic imaging modality that produces cross-sectional transaxial, coronal, sagittal, and oblique images that display anatomic structures of the head or body. Additionally, this system is capable of non-contrast enhanced imaging, such as MRA. MRI (magnetic resonance imaging) images correspond to the spatial distribution of protons (hydrogen nuclei) that exhibit nuclear magnetic resonance (NMR). The NMR properties of body tissues and fluids are: ·Proton density (PD) (also called hydrogen density) ·Spin-lattice relaxation time (T1) ·Spin-spin relaxation time (T2) ·Flow dynamics ·Chemical Shift Depending on the region of interest, contrast agents may be used. When interpreted by a trained physician, these images yield information that can be useful in diagnosis.

Device Story

Vantage Orian 1.5T is a 1.5 Tesla MRI system utilizing Pianissimo scan noise reduction technology; features 1.4m short magnet; maximum field of view 55x50cm. Includes AiCE Reconstruction Processing Unit for MR, a deep learning-based image reconstruction algorithm. System acquires proton density, T1, T2, flow dynamics, and chemical shift data to produce cross-sectional images. Operated by trained clinicians/technicians in clinical settings. AiCE processes raw MR data to enhance image quality; output viewed by radiologists for diagnostic decision-making. Benefits include improved image quality and diagnostic confidence. This submission expands AiCE application to additional anatomical regions (spine, MSK, pelvis, abdomen, breast, cardiac) without hardware/software changes.

Clinical Evidence

Bench testing included a model observer study for low contrast detectability, SNR, and contrast performance. A human observer study involved 6 board-certified radiologists evaluating 55 studies, demonstrating a statistical preference for AiCE compared to standard performance filters. Results indicate performance is equivalent or superior to the predicate device.

Technological Characteristics

1.5T MRI system; 1.4m short magnet; 55x50cm FOV. Includes Pianissimo noise reduction. AiCE Reconstruction Processing Unit utilizes deep learning reconstruction. Complies with IEC 60601-2-33:2010+A1:2013+A2:2015 for SAR and dB/dt limits. Designed under 21 CFR 820 and ISO 13485.

Indications for Use

Indicated for diagnostic imaging of head or body anatomic structures in patients requiring cross-sectional transaxial, coronal, sagittal, or oblique MRI, including non-contrast MRA. Contraindications include presence of ferromagnetic objects or conditions incompatible with MRI.

Regulatory Classification

Identification

A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).

Special Controls

*Classification.* Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

#### 22. SUMMARY OF DESIGN CONTROL ACTIVITIES

No change from the previous predicate submission, K193021. A declaration of conformity with design controls is included in this submission.

#### 23. SAFETY

This device is designed and manufactured under the Quality System Regulations as outlined in 21 CFR § 820 and ISO 13485 Standards.

This submission is a modification that expands the clinical regions for the AiCE Deep Learning Reconstruction. There are no changes to the software and hardware from the previous Pre-Market Notification 510(k) K193021.

{7}------------------------------------------------

## 24. TESTING

AiCE deep learning reconstruction underwent performance (bench testing) using a model observer study to determine that image low contrast detectability was maintained or improved, accompanied with other bench testing of SNR and contrast performance. Additionally, a human observer study was conducted with 6 board certified radiologists and 55 studies that demonstrated a statistical preference of AiCE when compared to other performance filters. The results of the testing demonstrated that AiCE performed either at the same level or above the performance of the commercially available predicate device.

### 25. SUBSTANTIAL EQUIVALENCE

Canon Medical Systems Corporation believes that the Vantage Orian 1.5T, MRT-1550, V6.0, Magnetic Resonance Imaging (MRI) System with AiCE Reconstruction Processing Unit for MR is substantially equivalent to the previously cleared predicate device, Vantage Orian 1.5T, MRT-1550, V6.0, As there is no change to the hardware and software of the predicate device. Additionally, the testing conducted demonstrates that the device performance is equivalent to the predicate device for the anatomical regions that are stated above.

#### 26. CONCLUSION

The Vantage Orian 1.5T, MRT-1550, V6.0 with AiCE Reconstruction Processing Unit for MR does not have any change for the indications for use or the intended use of the device. Bench testing and volunteer clinical imaging additionally conducted does not change the conclusion that the subject device is safe and effective for its intended use.
