Device Story

PixelShine is a medical imaging application for CT image noise reduction. It receives CT DICOM images over a user network, processes them using a non-linear filter to reduce noise and enhance image quality, and routes the processed images to PACS or diagnostic workstations. The system operates as a network server on customer-provided off-the-shelf PC hardware, requiring no direct user interaction (no mouse/keyboard) after installation by trained personnel. Radiologists view the enhanced images alongside original images on existing workstations to assist in clinical diagnosis. The device benefits patients by providing improved image quality for diagnostic review.

## Technological Characteristics/Principles of Operation

PixelShine is a medical imaging application that runs on an AlgoMedica-specified, customer's Off-the-Shelf Personal Computer (PC) and performs noise reduction processing and transfer of CT DICOM images over a user network. Once installed by AlgoMedica trained personnel, PixelShine operates independently, without the need for I/O devices such as mouse and keyboard. It is indicated for assisting radiologists and other medical specialists in arriving at their own diagnosis. The technology for noise reduction is based on a non-linear filter, which reduces noise in the original image. Figure 5.1 depicts a typical deployment of the PixelShine at a customer site.

## PixelShine Components and Hardware Requirements

The following components and hardware requirements are an integral part of the PixelShine:

- PixelShine Version 1 Software Package; .
- . Linux Operating System;
- DICOM Server software installed on PixelShine provides all DICOM communications: . and
- . AlgoMedica specified off-the-shelf PC Hardware (minimum Requirements) containing:
- -Intel CPU with 4 cores;
- -16GB RAM;
- -500GB hard drive; and
- Two 1 Gigabit Ethernet ports -

### PixelShine Functional Capabilities

{6}------------------------------------------------

The following functions are associated with performance of the PixelShine (reference

## Figure 5.1):

- Operates in a network server mode environment; .
- Functions as a DICOM device on the user network; .
- Capable of receiving CT images from different DICOM devices over the ● network:
- Capable of receiving images from multiple DICOM devices; ●
- Processes the CT images upon receiving them from a DICOM device; and ●
- . Sends the processed CT image to one or more destination DICOM devices.

Figure 5.1 – Pixel Shine Functional Block Diagram (deployment scenario)

Image /page/6/Figure/9 description: The image shows a diagram of a CT scanning process. The CT scanner sends original CT images to PACS and technologists' workstations. The original CT images are also sent to the AlgoMedica PixelShine Server, which enhances the quality of the images. The enhanced quality images are then sent to PACS and diagnostic workstations.

Note: PixeShine receives original CT images, processes them and routes the enhanced quality images to a PACS system. As in current practice, the technologist is able to view both the processed images on his workstation and take appropriate action as necessary. Both the original and processed images can be stored on the PACS server.

### Summary of Non-Clinical Performance and Safety Testing

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

The following non-clinical performance testing was performed with satisfactory results. All of the testing was performed with the use of an approved testing protocol. Details of each test, including protocols and reports are located in Appendix E of this 510(k).

- Unit Integration Testing Pass; .
- PixelShine System-Level-Testing Pass; .
- PixelShine Verification Testing Pass; and .
- PixelShine Validation Testing Pass. .

### Substantial Equivalence Discussion

## Medic Vision Brain Technologies Ltd. – SafeCT (K100372)

The PixelShine is substantially equivalent to the devices previously cleared by FDA (reference 510(k) – K100372). AlgoMedica claims this equivalence because the proposed device has an equivalent intended use, theory of operation, operating principals, and operational specifications as compared to the predicate device. The similarities and differences between the proposed and predicate device have been delineated within a comparison chart which has been included in Section 12 of this 510(k) submission.

## Conclusion Statement

The AlgoMedica PixelShine has the same intended use as the predicate device. Any technological changes to the device do not raise new questions of safety or effectiveness. Performance testing, along with verification and validation activities demonstrate that the AlgoMedica PixelShine is as safe and effective, and performs as well as the predicate device. Therefore, the AlgoMedica PixelShine can be considered substantially equivalent to the predicate device.
