Yes. GratiView is an Indian DICOM viewer designed for modern medical imaging workflows. It supports Windows, macOS, and Linux and includes features such as multiplanar reconstruction (MPR), GPU-based volume rendering, and advanced image viewing tools.

Can a DICOM viewer connect to a PACS server?

Yes. A PACS DICOM viewer can connect to a PACS server to access and review medical imaging studies. PACS stands for Picture Archiving and Communication System, which is used to store, manage, retrieve, and share medical images within healthcare organizations.

What does DICOM stand for?

DICOM stands for Digital Imaging and Communications in Medicine. It is a standard used to store, transmit, and manage medical images and related information. DICOM supports different DICOM file types used for CT, MRI, X-ray, ultrasound, and other imaging studies.

What is the difference between a DICOM viewer and PACS?

A DICOM viewer is mainly used for image viewing and analysis, while PACS is a complete system for storing, managing, retrieving, and sharing medical imaging studies. A viewer can connect to a PACS server so radiologists can access studies without manually transferring each image file.

How do I choose the right DICOM viewer?

Choosing the right DICOM viewer depends on your workflow and requirements. Look for features such as MPR, 3D visualization, measurements, fast image viewing, PACS connectivity, supported operating systems, and ease of use.
