Yes
The device description mentions "semi-automatic labeling of normal brain structures and tissues," which, combined with the performance study comparing this feature to manual labeling, strongly suggests the use of an algorithm that learns from data to perform this task, characteristic of ML.
No.
Deep Gray is a software device intended for measurement, visualization, processing, and analysis of brain images. It does not provide treatment or therapy, but rather aids in diagnosis and assessment by providing quantitative information about brain structures.
No
Explanation: A diagnostic device identifies or detects a disease, condition, or health status. While Deep Gray processes and visualizes MR images for volumetric quantification, it does not directly diagnose any disease or condition; rather, it provides measurements for "any brain structure and tissue." This information can aid in diagnosis but is not diagnostic on its own.
Yes
The device description explicitly states "Deep Gray is a software device" and the features listed are all software-based functionalities for image processing, analysis, and reporting. There is no mention of accompanying hardware components that are part of the medical device itself.
Based on the provided information, this device is NOT an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, tissue) to provide information for diagnostic purposes. They perform tests outside of the body.
- Deep Gray's Function: Deep Gray processes and analyzes images of the brain obtained from an MR scanner. It measures volumes of structures within the body based on these images. It does not interact with or analyze biological specimens.
Therefore, Deep Gray falls under the category of medical image processing and analysis software, not an In Vitro Diagnostic device.
No
The input explicitly states "Control Plan Authorized (PCCP) and relevant text: Not Found", which does not meet the criteria for a "Yes" answer.
Intended Use / Indications for Use
Deep Gray is intended to measure the volume of any brain structure and tissue from a set of MR images. It provides visualization tools, basic and advanced regions of interest drawing features and volumetric quantification. Deep Gray is to be used by trained physicians.

Device Description
Deep Gray is a software device that provides the following features:
- Import of MR brain images (DICOM 3.0 format).
- Multi-frame and multi-orientation image display.
- Basic regions of interest drawing tools: free hand drawing, filled polygon drawing. Labels can be associated with drawn objects.
- Advanced drawing tool: semi-automatic labeling of normal brain structures and tissues.
- Generation of a report listing the volumes of labeled structures and tissues.
The operator can choose to manually draw and label brain structures and tissues, or they can chose to perform a semi-automatic labeling, followed by visual inspection and manual adjustment. The Deep Gray system does not have any adverse affects on health. This tool measures and displays the volume of regions of interest. The operator can choose to accept, modify, or reject the volume and/or label suggested by the program.

§ 892.2050 Medical image management and processing system.
(a)
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.(b)
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).
