The description details a noise reduction algorithm using wavelets and image guided filtering, which are traditional image processing techniques, not explicitly AI or ML. There is no mention of AI, ML, or related concepts like neural networks or training data for model development.
No
The device is an image processing software designed to enhance MRI images by reducing noise, not to diagnose, treat, or prevent a disease or condition.
No
The device is described as image processing software for image enhancement and noise reduction in MRI images. It improves image quality (SNR) but does not provide diagnosis or clinical decision support. Its output is enhanced images sent to PACS, alongside original images, to aid human interpretation rather than make a diagnostic determination itself.
Yes
The device is explicitly described as "image processing software" and its function is to enhance MRI images. The description details the software's algorithms and how it receives, processes, and sends images, without mentioning any associated hardware components that are part of the device itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The ZOOM Image Enhancement System processes MRI images, which are generated from the human body using external energy (magnetic fields and radio waves). It does not analyze biological specimens.
- Intended Use: The intended use is for image enhancement in MRI images, not for analyzing biological samples.
The device is clearly an image processing software for medical imaging, specifically MRI. This falls under the category of medical devices, but not specifically In Vitro Diagnostics.

Intended Use / Indications for 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 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.

Description of the test set, sample size, data source, and annotation protocol
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.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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.
Results for various sequences:
- For spin echo large phantom protocol in ACR quality control 2015, the software shall increase SNR by at-least 10% in slice 7 ACR data without compromising high contrast resolution in slice 1 and low contrast resolution in slice 11. (Result: Pass)
- For fast spin echo sequences with slice thickness in the range 2-5mm and in-plane resolution in the range 0.6-1.4 mm, the software shall increase SNR by at-least 10% in slice 7 ACR data without compromising high contrast resolution in slice 1 and low contrast resolution in slice 11. (Result: Pass)
- For gradient echo sequences with slice thickness in the range 2-5mm and in-plane resolution in the range 0.6-1.4 mm, the software shall increase SNR by at-least 10% in slice 7 ACR data without compromising high contrast resolution in slice 1 and low contrast resolution in slice 11. (Result: Pass)
- For spin echo small phantom protocol in ACR quality control 2015, the software shall increase SNR by at-least 10% in slice 7 ACR data without compromising high contrast resolution in slice 1 and low contrast resolution in slice 11. (Result: Pass)

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.
