Used by clinicians to facilitate image presentation on monitors; aids diagnostic workflow by enhancing image quality and managing patient data. Benefits include improved visualization of medical images and streamlined data handling.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Software-only device for off-the-shelf PC. Features DICOM connectivity, image processing algorithms (frequency, equalization, hybrid, integral), and grid suppression. Operates on standard PC hardware. No specific materials or energy sources defined as it is software.

Indications for Use

Indicated for processing and display of medical images from X-ray, CT, MRI, Ultrasound, Nuclear Medicine, and other DICOM modalities. Contraindicated for primary image diagnosis in mammography.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

### 9. Description of Device

REGIUS Unitea is a software which is intended for installation on an off-the-shelf PC meeting or exceeding minimum specifications. REGIUS unitea software controls and manages the cassette type CR (Computed Radiography) such as REGIUS MODEL 170,190 and 110 that is connected via the network. REGIUS Unitea receives and displays images from other DICOM compliant modalities connected via the network and whole use digital media such as DVD/CD-R, DSC and USB memory cards connected as disk drives

REGIUS Unitea software has the following set of features.

{1}------------------------------------------------

- 1. Feature to automatically obtain patient demographic information (Name, Age, Sex, Date of Birth, etc) from Hospital Information Systems.
- 2. Feature to specify the reading condition (Sampling Sensitivity of the sensor and so on) of the connected CR device.
- 3. Receive and store image data from REGIUS MODEL 170, 190 and 100 CR, other DICOM compliant modalities and digital media (such as DVD/CD-R, DSC and USB memory cards).
- 4. Display image data received from the REGIUS MODEL 170, 190 and 100 CR, other DICOM compliant modalities and digital media (such as DVD/CD-R, DSC and USB memory cards).
- 5. Feature to apply image processing to images received from REGIUS MODEL 170. 190 and 100 CR.

Image processing applied includes:

- 1) Contrast and Density Adiustments.
- 2) F-processing: Frequency processing that highlights fine details in the image, or enhances detail that has been blurred, without affecting density.
- 3) E-processing: Equalization processing that improves the image quality that cannot be fully expressed by the film latitude due to wide distribution of the subject.
- 4) H-processing: Hybrid processing which combines frequency enhancement processing and equalization processing based on multi-resolution analysis.
- 5) 1- processing: Integral processing that automatically adjusts luminance (film density) and contrast of an image.
- 6) Masking: Filis black on the area of the frame where X-ray is not irradiated.
- 7) Rotating/Flipping: Rotate/Reverse an image.
- 8) Re-sampling and Resizing: Function that re-samples and resizes the image data.
- 9) Stitching: Function that manually or automatically recognizes long body part and stitch multiple images to create a composite image. The stitched image can be divided into several small images before outputting to a storage device or film printer.
- 10) Grid Suppression Function to suppress the grid and moire patterns within the image exposed with the grid
- 11) Function to add digital marker for patient information and to add annotations to the image data
- 12) Function that outputs image data to a printer, other DICOM devices and digital media.

#### 10. Intended Use

The REGIUS Unitea software is intended for installation on an off-the-shelf PC meeting or exceeding minimum specifications. The REGIUS Unitea software primarily facilitates processing and presentation of medical images on display monitors suitable for the medical task being performed. The REGIUS Unitea

{2}------------------------------------------------

software can process and display images from the following modality types: Plain X-ray Radiography, X-ray Computed Tomography, Magnetic Resonance imaging, Ultrasound, Nuclear Medicine and other DICOM compliant modalities. The REGIUS Unitea must not be used for primary image diagnosis in mammography.

#### 11. Substantial Equivalence to Predicate Device

REGIUS Unitea is substantially equivalent to our REGIUS CS-2000 and CS-3000, 510(k) number: K051523. Comparison of the principal characteristics of these devices is shown in the Section 3.

#### 12. Safety Information

REGIUS Unitea introduces no new safety and efficacy issues other than those already identified with the predicate device. The results of a hazard analysis, combined with the appropriate preventive measure taken indicate that the device is of minor level of concern as per the May 11, 2005 issue of the "Guidance for the Content of Premark Submissions for Software Contained in Medical Devices".
