No.
The device is described as a digital image processing system that displays two images side-by-side and performs video scan rate conversion. Its intended use is to combine and display diagnostic images (X-ray, nuclear medicine, MR, ultrasound) from various sources for use on display monitors or other apparatus. It does not exert a therapeutic effect on a patient.

SplitScreen is described as a digital image processing system that displays two images side-by-side and performs video scan rate conversion. Its intended use is to combine and display medical images from various modalities (X-ray, nuclear medicine, MRI, ultrasound) for viewing on monitors or other apparatus. It does not perform analysis, interpretation, or diagnosis based on these images. Its function is to facilitate the display of images for interpretation by a human, rather than performing a diagnostic assessment itself.
No
The device description explicitly states "SplitScreen is a digital image processing systems" and describes hardware components like accepting input signals and outputting video, indicating it is a hardware system with image processing capabilities, not solely software.
Based on the provided text, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The intended use and device description clearly state that SplitScreen processes and displays medical images from modalities like X-ray, nuclear medicine, MRI, and ultrasound. These are imaging techniques that capture images of the body directly, not by analyzing biological samples.
- The device description focuses on image processing and display. The core function is to combine and display two images side-by-side with scan rate conversion. This is a function related to medical imaging display, not laboratory testing of biological samples.
- The performance studies mentioned relate to video standards and image resolution. The testing focuses on compliance with standards like RS-170, RS-343A, and SMPTE RP-133, which are relevant to video signals and image display quality. There is no mention of performance metrics related to diagnostic accuracy based on analyzing biological samples (like sensitivity, specificity, etc.).
In summary, SplitScreen is a medical imaging display and processing device, not a device used for in vitro diagnostic testing of biological specimens.

Intended Use / Indications for Use
The use of SplitScreen is indicated whenever two images are required to be shown together side-by-side in a single image/display, and a high-line rate (e.g., 1049 lines @ 30 frames/sec or 1249 lines @ 25 fps) video signal is required. . . Examples include conversion / combining of X-ray (stationary, C-arm, angiography, etc.), nuclear medicine, magnetic resonance, and/or ultrasound images either directly from their source, or from an intermediate storage device (like a video tape or video disk), for use on display monitors, optical, tape, disk, or other apparatus requiring a high-line rate video signal.

Device Description
SplitScreen is a digital image processing systems that can display 2 pictures side-by-side on a single video monitor. Additionally, SplitScreen has provisions for video scan rate conversion.
SplitScreen accepts two input signals at various scan rates, and it outputs video at high-line rate. Both images share the full video frame by splitting them with a vertical boundary. The position of the boundary can be adjusted right or left (thus adjusting the relative amounts of each image viewed), and each image can be panned horizontally within each split area. The result is two images, each of which is full height but cropped horizontally. The output composite image is compatible with high-resolution monitors capable of displaying high-line rate video which is compatible with EIA standard RS-343A.
When used in conjunction with a Video Scan Converter capable of converting from high-line to low-line rate, such as Merlin's UniScan (submission K953398), the resulting SplitScreen image can be recorded on standard VHS, S-VHS, and other readily available recorder formats, and can be viewed with standard video monitors.

Summary of Performance Studies
SplitScreen was tested to ensure that it meets the appropriate requirements of RS-170 and RS-343A. The data demonstrates that SplitScreen meets these standards, as appropriate to the specific signal, as is the case for the predicate devices.
In addition, SplitScreen was tested in accordance with SMPTE RP-133. The system correctly compensates for aspect ratio changes in accordance with the requirements of the particular scan conversion selected. In addition, the system permits low-contrast imaging resolution at the 1% level.
SplitScreen is electrically compatible with industry standard monochrome video signals. The image quality is preserved (within the limits of standard video technology and the line rates selected).

(a)
Identification. A medical image communications device provides electronic transfer of medical image data between medical devices. It may include a physical communications medium, modems, and interfaces. It may provide simple image review software functionality for medical image processing and manipulation, such as grayscale window and level, zoom and pan, user delineated geometric measurements, compression, or user added image annotations. The device does not perform advanced image processing or complex quantitative functions. This does not include electronic transfer of medical image software functions.(b)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 892.9.

Intended use of the device:
Summary of how the technological characteristics compare to predicate device(s):
Summary of (nonclinical) performance tests and how their results support a determination of substantial equivalence:
Conclusions drawn from the performance tests:
The intended use for SplitScreen is conversion and combining of X-rav (stationary, C-arm, angiography, etc.), nuclear medicine, magnetic resonance, and ultrasound images either directly from their source, or from an intermediate storage device (like a video tape or video disk), for use on display monitors, optical, tape, disk, or other apparatus requiring a video signal.
The use of SplitScreen is indicated whenever two images are required to be shown together side-by-side in a single image/display, and a high-line rate (e.g. 1049 lines (@ 30 frames/sec or 1249 lines @ 25 fps) video signal is required. SplitScreen is not intended to have any patient contact.
SplitScreen and the predicate devices are real-time video processing systems designed to convert monochrome video images from one format to another (e.g., low line-rate to high line-rate, or visa versa) and/or to convert from full size/full view images to other size/other view images. SplitScreen and all of the predicate devices utilize similar technology to perform the scan conversion. These systems all convert the incoming analog video signal to digital form using 8-bit analog-to-digital converters, process the signals in the digital domain, and convert back to analog video using 8-bit digital-to-analog converters for the output.
SplitScreen and one of the other predicates (Perkins IDP-5100) produce outputs where parts of one input image cover parts of the other input. since full sized/full view images must either be sized or cropped to allow multiple images on a single display. The Perkins unit does this by shrinking one of the images to quarter size (covering up an equivalent amount of the second image), while SplitScreen does this by horizontally cropping both images, keeping both of them full height.
SplitScreen was tested to ensure that it meets the appropriate requirements of RS-170 and RS-343A. The data demonstrates that SplitScreen meets these standards, as appropriate to the specific signal, as is the case for the predicate devices.
In addition, SplitScreen was tested in accordance with SMPTE RP-133. The system correctly compensates for aspect ratio changes in accordance with the requirements of the particular scan conversion selected. In addition, the system permits low-contrast imaging resolution at the 1% level.
SplitScreen is electrically compatible with industry standard monochrome video signals. The image quality is preserved (within the limits of standard video technology and the line rates selected).
