Intended Use
SubtleHD is an image processing software that can be used for image enhancement of all body parts MRI images. It can be used for noise reduction and increasing image sharpness.
Device Description
SubtleHD is Software as a Medical Device (SaMD) consisting of a software algorithm that enhances images taken by MRI scanners. As it only processes images for the device has no user interface. It is intended to be used by radiologists and technologists in an imaging center, clinic, or hospital. The SubtleHD software can be used with MR images acquired as part of standard of care and accelerated MRI exams as the input. The outputs are the corresponding images with enhanced image quality. Original DICOM images are passed onto the SubtleHD software as an input argument and the enhanced images are saved in the designated location prescribed when running the SubtleHD software. The functionality of SubtleHD (noise reduction and sharpness enhancement) is identified from the DICOM series description and/or through configuration is specified as configuration files and OS environment variables.
SubtleHD software implements an image enhancement algorithm using a convolutional network based filtering. Original images are enhanced by running through a cascade of filter banks, where thresholding and scaling operations are applied. A single neural network is trained for adaptive noise reduction and sharpness increase. The parameters within the neural network were obtained through an image-guided optimization process. Additional nonlocal mean based denoising and unsharp masking based sharpening filters are applied to the deep learning processed image.
The software operates on DICOM files, enhances the images, and sends the enhanced images to any desired destination with an AE Title (e.g., PACS, MR device, workstation, and more). Enhanced images coexist with the original images.

Intended Use
The device is intended to provide entirely non-invasive electromagnetic stimulation of pelvic floor musculature for the purpose of rehabilitation of weak pelvic muscles and restoration of neuromuscular control for the treatment of male and female urinary incontinence.
Device Description
The BTL-398 is a non-invasive therapeutic device that delivers magnetic pulses to stimulate the pelvic floor muscles for the treatment of urinary incontinence in adult population. The BTL-398 device is intended for professional use in healthcare facilities as a prescription use only. The BTL-398 consists of a main unit and a Chair Applicator. The main unit consists of the electromagnetic field generators, the microprocessor-driven control unit, and the touch-screen control panel. The Chair Applicator is designed for non-invasive treatment of urinary incontinence. The magnetic coil is in the center of the seat, and its position is user-adjustable during therapy. Ongoing therapy is indicated by illuminated segments. The Chair Applicator is designed for precise patient positioning, ensuring the most appropriate posture before and during therapy. Prior to High-Intensity Focused Electromagnetic (HIFEM) therapy, the seat height and coil position can be adjusted using an attached remote controller. The Dynamic HFEM Technology (DHT) feature ensures the coil is optimally positioned at the right location beneath the patient before starting therapy. At the start of therapy, air is circulated through the seat cushion with the Pressure Wave Technology (PWT) feature (intensity of the PWT function is set based on patient feedback). The PWT feature helps patients maintain the correct therapeutic position during therapy. Both the PWT and DHT features can be readjusted, and the PWT feature can be turned off, at any time during the session. The touch screen display guides the user step-by-step through the entire therapy procedure. During therapy, the screen displays information about the applied therapy, remaining therapy time, and main therapy parameters. Therapy is administered through clothing.

Device Description
The BTL-754 is a medical device containing two laser wavelengths. A laser is a device that can generate light in the visible or invisible part of the electromagnetic spectrum. The generation of radiation occurs by means of so-called stimulated emission, thanks to which its beam has specific properties - the laser beam is well directed and can propagate over long distances without much divergence. It can also be focused into a very small spot where a very high intensity is achieved.
The BTL-754 consists of a main unit, articulated mirror arm and applicator. The main unit is equipped with a color touch screen with a wide that makes the device easy to use. The onscreen information informs the operator through the entire therapy procedure. The therapeutic parameters are easily set using the touch screen. During therapy, the screen displays information about therapy parameters. The device is equipped with the Emergency laser stop button for immediate termination of the laser emission.

Intended Use
AiMIFY is an image processing software that can be used for image enhancement in MRI images. It can be used to increase contrast-to-noise ratio (CNR), contrast enhancement (CEP), and lesion-to-brain ratio (LBR) of enhancing tissue in brain MRI images acquired with a gadolinium-based contrast agent. It is intended to enhance MRI images acquired using standard approved dosage per the contrast agent's instructions for use.
Device Description
The AiMIFY device is a software as a medical device consisting of a machine learning software algorithm that enhances images taken by MRI scanners. AiMIFY consists of a software algorithm that improves contrast-to-noise ratio (CNR), contrast enhancement (CEP), and lesion-to-brain ratio (LBR) of Gadolinium-Based Contrast Agent (GBCA) enhanced T1-weighted images while maintaining diagnostic performance, using deep learning technology. It is a post-processing software that does not directly interact with the MR scanner and does not have a graphical user interface. It is intended to be used by radiologists in an imaging center, clinic, or hospital. The AiMIFY software uses T1 pre and post-contrast MR images acquired as part of standard of care contrast-enhanced MRI exams as the software input. The outputs are the corresponding images with enhanced contrast presence. AiMIFY enhances DICOM images.
AiMIFY image processing software uses a convolutional network based algorithm to enhance the AiMIFY-contrast images from pre-contrast and standard-dose post-contrast images. The image processing can be performed on MRI images with predefined or specific acquisition protocol settings as follows: gradient echo (pre- and post-contrast), 3D BRAVO (pre- and post-contrast), 3D MPRAGE (preand post-contrast), 2D T1 spin echo (pre- and post-contrast), T1 FLAIR/ inversion recovery spin echo (pre- and post-contrast).
The AiMIFY image is created by AiMIFY and sent back to the picture archiving and communication system (PACS) or other DICOM node by the compatible MDDS for clinical review.
Because the software runs in the background, it has no user interface. It is intended to be used by radiologists in an imaging center, clinic, or hospital.
Note, depending on the functionality of the compatible MDDS, AiMIFY can be used within the facility's network or remotely. The AiMFY device itself is not networked and therefore does not increase the cybersecurity risk of its users. Users are provided cybersecurity recommendations in labeling.

SubtleSYNTH is a software as a medical device consisting of a software machine learning algorithm that synthesizes a SynthSTIR contrast image of a case from T1-weighted and T2-weighted spine MR images.
Device Description
The SubtleSYNTH device is a software as a medical device consisting of a machine learning software algorithm that synthesizes a SynthSTIR contrast image of a case from T1-weighted and T2-weighted MR images. It is a post-processing software that does not directly interact with the MR scanner. Once a MR scan is acquired, a technologist sends the study from the scanner to a compatible medical device data system (MDDS) via the DICOM protocol. The compatible MDDS, then, makes the images available to SubtleSYNTH for processing.
SubtleSYNTH uses a convolutional network-based algorithm to synthesize an image with desired contrast weighting from other, previously obtained sequences such as T1- and T2-weighted images. The image processing can be performed on MRI images with predefined or specific acquisition protocol settings.
The SynthSTIR image is created by SubtleSYNTH and sent back to the picture archiving and communication system (PACS) or other DICOM node by the compatible MDDS for clinical review.
