Intended Use

SwiftMR is a stand-alone software solution intended to be used for acceptance, enhancement and transfer of all body parts MR images in DICOM format. It can be used for noise reduction and increasing image sharpness for MR images. SwiftMR is not intended for use on mobile devices.

Device Story

SwiftMR is a stand-alone software (SaMD) that enhances MRI images. It receives DICOM images from PACS or MRI scanners; processes them in the background using a deep learning model and sharpening filters; and outputs enhanced DICOM images back to PACS or the MRI device. Operated by radiology technologists in clinical settings, the device allows adjustment of denoising (levels 0-8) and sharpening (levels 0-5). It automates image quality enhancement, allowing for potential scan time reduction up to 50%. The system includes a user interface for monitoring processing status and system administration. By improving signal-to-noise ratio and image sharpness, the device assists clinicians in viewing diagnostic images, potentially improving diagnostic confidence.

Clinical Evidence

Bench testing only. Validation used retrospective clinical images across various manufacturers (Siemens, GE, Philips, etc.), field strengths (0.25T-3.0T), and anatomical regions. Noise reduction performance: SNR increased by ≥40% for ≥90% of the dataset at level 1. Sharpness performance: FWHM decreased by 0.13% (DL model) to 4.5% (filter level 5) for ≥90% of the dataset. Dataset included adults (22-93 yrs) and pediatrics (0-21 yrs).

Technological Characteristics

SaMD operating on off-the-shelf PC hardware. Uses a convolutional neural network-based filtering algorithm for noise reduction and sharpening. Processes DICOM-compliant images. Connectivity via PACS/MRI integration. No specific materials or energy sources as it is software-only.

Indications for Use

Indicated for patients of all ages (pediatric and adult) undergoing MRI scans of any body part (including neuro, musculoskeletal, cardiac, abdomen, pelvis, and breast) to enhance image quality via noise reduction and sharpness adjustment.

PREDICATE DEVICE Primary Predicate Device: SwiftMR - K220416 by AIRS Medical, Inc., Class II, CFR 892.2050, classification with product code LLZ. ### IV. DEVICE DESCRIPTION SwiftMR, is software used as a Medical Device (SaMD) consisting of a software algorithm that enhances images taken by MRI scanners. The device only processes DICOM images for the end User and is intended to be used by radiology technologists in an imaging center, clinic, or hospital. The device's inputs are MRI images in DICOM format. The deep learning algorithm produces enhanced images as outputs with reduced noise and increased sharpness in DICOM format. The deep learning algorithm performs noise reduction with the ability of adjusting the denoising level 0 to level 8, and sharpening filter performs the sharpening function with the ability of adjusting the sharpness level from level 0 to level 5. SwiftMR provides an automatic image quality enhancement function for MR images acquired in various environments. SwiftMR can only be used for professional purposes and is not intended for use on mobile devices. SwiftMR 's automation procedure is as follows: - . Receive MR images that are in DICOM format from PACS or from MRI - Image quality enhancement using Deep Learning model and sharpening . filter - Transfer enhanced MR image as DICOM format to PACS or to MRI . There is one deep learning model that can be applied to images from any MRIs with field strength of 0.25T, 0.6T, 1.5T, 3.0T. After integration with the facilities PACS. SwiftMR performs image processing in the background automatically.

The logo consists of a large blue letter "A" with a curved line extending from the middle of the left side of the "A". To the right of the "A" are the words "AIRS" and "MEDICAL" stacked on top of each other in black font. The logo is simple and modern, and the use of blue and black gives it a professional look. the same time. SwiftMR allows logged-in users to use its functions and view the processing status. When logged in as the System Admin, the function is available to the control automation procedure and system change settings. On the User side. the User can retrieve the results of image processing in the form of a worklist by login to the user account. The software provides three main functions, which are image processing, quality check and progress monitoring. The software is intended to run automatically in the background so that it does not interrupt the workflow of users. When the user executes MR scans as he/she usually does, the newly acquired images are automatically uploaded to the server and registered in the database (DB) for image processing. Once image processing is complete, the images are sent to PACS or to MR device. If the user wishes to monitor this automated workflow to check on the status of image processing, he/she can check the main page of the client application or toast messages will appear on the bottom right corner upon completion of each processing. After using the software, they should log out for security reasons. A settings menu is provided in the form of a user interface to enable system admin to modify software settings as required by the institution or respective user. #### V. INDICATIONS FOR USE SwiftMR is a stand-alone software solution intended to be used for acceptance, enhancement and transfer of all body parts MR images in DICOM format. It can be used for noise reduction and increasing image sharpness for MR images. SwiftMR is not intended for use on mobile devices. #### VI.

Validation testing indicated that as required by the risk analysis, designated individuals performed all verification and validation activities and that the results demonstrated that the predetermined acceptance criteria were met. {6}------------------------------------------------ Image /page/6/Picture/0 description: The image contains the logo for AIRS Medical. The logo consists of a large, stylized letter "A" in blue, with a curved line extending from the left side of the "A". To the right of the "A" are the words "AIRS" and "MEDICAL" stacked vertically, both in black, sans-serif font. The logo is simple and modern in design. The following tests were conducted for SwiftMR: - 1) Verification testing: Unit test. Integration/system test conducted. These tests passed. - 2) Validation testing: Performance test was conducted using retrospective clinical images for both noise reduction and sharpness increase functions. - A. For the noise reduction performance, acceptance criteria were defined that the signal-to-noise ratio (SNR) of the SwiftMR-processed image series is increased by 40% or more for at least 90% of the dataset for level 1 with an incremental 1% increase per each level. This test passed. - B. For the sharpness increase performance, acceptance criteria were defined that the FWHM of a selected region of interest (ROI) is decreased bv 0.13% (deep learning model). 0.43% (filter level 1). 1.7% (filter level 2). 2.3% (filter level 3), 3.6% (filter level 4), 4.5% (filter level 5) or more for at least 90% of the dataset. This test passed. The validation dataset consists of data of the following conditions: 1. Manufacturer: SIEMENS, GE, PHILIPS, CANON, ESAOTE, FONAR, FUJIFILM 2. Field Strength: 0.25T, 0.6T, 1.5T, 3.0T 3. Anatomical region: Body (breast, abdomen, and pelvis), Cardiac, Neuro (head, neck, and spine), Musculoskeletal (shoulder, wrist, hip, knee, and ankle) 4. Protocol: T1, T2, T2*, FLAIR, PD, DWI, MRA - 5. Demographics - age: Adults (22~93 yrs, 88.4%), Pediatrics (0~21 yrs, 11.6%) - gender: Male (44.8%), Female (55.2%) - 6. Time reduction range for reduced scan time images: up to 50% To show that the performance of the device is not hindered by site variability, in the validation dataset, we included data from sources not included in the training dataset. Therefore, it was demonstrated that SwiftMR performance was shown to be substantially equivalent to the predicate device. ### VIII. CONCLUSION The information presented in the 510(k) for SwiftMR contains adequate information, data, and nonclinical test results to demonstrate substantial equivalence to the predicate device. SwiftMR was shown to be substantially equivalent to the predicate device in the areas of technical characteristics, general function, application, and does not raise different questions of safety and effectiveness.
