Intended Use

ZOOM Image Enhancement System is an image processing software that can be used for image enhancement in MRI images. Enhanced images will be sent to PACS server and exist in conjunction to the original images.

Device Story

ZOOM is an image processing software for MRI enhancement; operates on a remote computer. Inputs: DICOM images from MRI host computer. Processing: noise reduction via wavelet decomposition, soft thresholding of wavelet sub-bands, and inverse wavelet transform reconstruction. Outputs: enhanced DICOM images sent to PACS server. Workflow: automated processing of received images; enhanced images stored alongside originals. Benefits: improves signal-to-noise ratio (SNR) by at least 10% without degrading contrast resolution, aiding clinical image quality.

Clinical Evidence

Bench testing only. Validation performed using 64 data sets acquired via ACR MRI phantom on GE 1.5T Excite, Siemens Avanto 1.5T, Philips Intera 1.5T, and Toshiba Titan 1.5T systems. Sequences included spin echo, fast spin echo, and gradient echo. Primary endpoint: SNR improvement of at least 10% in slice 7 of ACR phantom data without degrading high-contrast (slice 1) or low-contrast (slice 11) resolution. All tests passed.

Technological Characteristics

Software-based image enhancement. Operates on PC/PC-compatible hardware (Intel i3, 4GB RAM, 500GB HDD). OS: Windows 7. Input/Output: DICOM. Algorithm: Wavelet-based noise reduction with image-guided filtering. Connectivity: Networked (receives from MRI host, sends to PACS).

Indications for Use

Indicated for image enhancement of MRI images. No specific patient population, age, or gender restrictions are defined.

### 5. Device Description:

ZOOM Image Enhancement System is an image processing software that can be used for image enhancement in MRI images. ZOOM image enhancement software implements a noise reduction algorithm using wavelets and image guided filtering. Original images are decomposed into different wavelet sub bands and noise in each band is soft threshold. De-noised images are reconstructed from softthresholded images using inverse wavelet transform. The software, which is installed on a remote computer, receives DICOM images from MRI host computer, automatically processes the received images and sends the enhanced images to a PACS server. Enhanced images exist in conjunction to the original images.

## 7. Performance Testing:

ZOOM has been designed, verified and validated in compliance with FDA 21 CFR Part 820 requirements. The device has been validated through the use of ACR MRI PHANTOM. A total of 64 data sets were acquired using spin echo, fast spin echo and gradient echo based sequences from the following systems: GE 1.5T Excite, Siemens Avanto 1.5T, Philips Intera 1.5T and Toshiba Titan 1.5T. Parameters (slice thickness, field of view, matrix dimensions and number of averages) that effect the signal to noise ratio (SNR) were varied while acquiring the 64 data sets. These data sets were processed using ZOOM software for image enhancement and results are compared between original and processed images. Performance test results indicate that the ZOOM software improves SNR by at least 10% without degrading high and low contrast resolutions.

#### 8. Safety and Effectiveness:

Based on the ZOOM software performance test results and incorporated risk minimization methods in design, Zetta Medical Technologies concludes that this device is substantially equivalent to the predicate device.

#### 9. Conclusion:

ZOOM is an image enhancement software which has similar indications for use as predicate device. The main difference is that the predicate device is a multimodality image transfer/storage/enhancement system where as ZOOM (as of 7/27/2017) is strictly an MRI image enhancement system. Performance test results and incorporated risk minimization methods demonstrate that ZOOM is as safe and effective as predicate device.
