Intended Use

The WorkstationOne™ Breast Imaging Workstation is intended for use with a regionally approved digital mammography system. The workstation displays images from multiple modalities, which include X-ray mammography MG, breast US and breast MRI. The workstation allows selection, display, manipulation, quantification, markup, print composition and media exchange of breast images. Here, quantification refers to measurements (such as area and distance) within a region of interest that the radiologist manually draws on the images. Similarly, markup refers to graphics that are manually drawn by the radiologist to indicate a region of interest. Note that the region of interest is not automatically generated by the computer. The WorkstationOne™ Breast Imaging Workstation is intended for softcopy reading and interpretation of digital mammography images by Radiologists. The WorkstationOne™ Breast Imaging Workstation when used for interpretation of images acquired using a FFDM image acquisition system shall display the images only on FDA-cleared high-resolution monitors. The images used for primary diagnostic reading must be in a lossless format, unless lossy formats are approved for use in digital mammography.

Indications for Use

Indicated for softcopy reading and interpretation of digital mammography images (MG), breast ultrasound (US), and breast MRI by radiologists. Supports manual quantification and markup of regions of interest.

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).

Predicate Devices

#### 5.4. Device Description

The WorkstationOne™ is a diagnostic breast imaging workstation which consists of a software system that obtains breast imaging screening or diagnosis exams from PACS or Modalities; displays and manipulates the images for radiologists to perform interpretation task. The workstation also supports media exchange and film printing. Optionally, the workstation can interface with a reporting system to generate an interpretation report.

The enterprise workflow of the workstation follows IHE integration profiles, specifically, MAMMO (Mammography Image Profile) and RWP (Reporting Workflow Profile). The workstation can be configured to use mammographic specific hanging protocol and reading workflow. The workstation obtains the source images and CAD reports either as the recipient of the push of that data, or by querying and retrieving them from a PACS archive. In both models, DICOM is used. The images can only be the lossless compressed or non-compressed DICOM images.

Three Palm Software, LLC

The WorkstationOne™ is a software system that can be installed on an off-the-shelf general-purpose computer with one or two aray-scale high-resolution monitors and one color monitor. The high-resolution monitors are used to display digital mammography images and associated overlays for the purpose of primary interpretation by radiologists. The color monitor is used for selecting studies, displaying color images, navigating workflow, and other user interface elements. Optionally, a dedicated keypad or touchpad is included for ergonomic reasons.

## 5.5. Indications for Use

The WorkstationOne™ Breast Imaging Workstation is intended for use with a regionally approved digital mammography system. The workstation displays images from multiple modalities, which include X-ray mammography MG, breast US and breast MRI. The workstation allows selection, display, manipulation, quantification, markup, print composition and media exchange of breast images. Here, quantification refers to measurements (such as area and distance) within a region of interest that the radiologist manually draws on the images. Similarly, markup refers to graphics that are manually drawn by the radiologist to indicate a region of interest. Note that the region of interest is not automatically generated by the computer.
