Free Online DICOM Viewer

Yes, you can email DICOM images, but you must use proper encryption and security measures. DICOM files contain sensitive patient information, so sending them without encryption can break privacy laws like HIPAA. Use secure email platforms or encrypted ZIP files for safe and compliant transfer.

DICOM images are medical images saved in the DICOM (Digital Imaging and Communications in Medicine) format. They include both the image, such as an X-ray, CT, or MRI, and important patient data like name, ID, and scan details. It provides safe and standard image sharing and viewing across healthcare systems.

Uncompressed DICOM images can range from 5 MB (X-ray) to over 500 MB (MRI or CT series). Compressed DICOM files that use JPEG 2000 or lossless formats are usually 30–70% smaller, depending on the modality and resolution. Compression lowers storage costs without affecting diagnostic image quality significantly.

Several free DICOM viewers support 3D imaging, including Medicai free DICOM Viewer, RadiAnt (with a free trial), Weasis, and Horos (for Mac users). These tools help view CT and MRI scans in various planes or as 3D images, ideal for radiology review, education, or research without a license fee.

A PACS system uses the DICOM standard to manage medical images. It helps healthcare providers store, retrieve, view, and share images from different devices. DICOM makes sure that images from CT, MRI, X-ray, and ultrasound machines are saved consistently. It provides seamless communication among imaging devices, workstations, and healthcare providers.

The DICOM standard is used for medical images like X-rays, CT scans, MRIs, ultrasounds, PET scans, and radiation therapy images. These files contain both the images and important patient information. It helps doctors and healthcare providers easily view, store, and share these images across different medical systems.

DICOM handles storing and sharing medical images. HL7 and FHIR manage patient data and clinical processes. Together, they offer safe and complete sharing of images. DICOM manages the images, while HL7 or FHIR links patient records, orders, and reports in healthcare systems.

You can download DICOM images from a hospital or PACS system, but only authorized users can access them. Patients can request copies through a patient portal or the medical records department. Downloads usually come in DICOM format, that are viewable with free DICOM viewer software for personal or clinical use.

Yes. You can encrypt DICOM files using TLS (Transport Layer Security) to keep data safe during transmission. It keeps patient information and medical images private and protected when shared over networks. It also helps meet compliance standards like HIPAA and supports safe teleradiology and remote diagnostics.

Yes, you can convert DICOM files into JPEG, PNG, PDF, NIfTI, STL, and other formats using specific software or tools like the Medicai DICOM viewer. These conversions help you to share, view, or process medical images outside of clinical systems while keeping their diagnostic quality intact.

Online DICOM viewers rely on stable internet connections and modern browsers, which can affect performance with large datasets or high-resolution images. Free versions may lack advanced features like 3D rendering or PACS integration. Security risks exist if the platform lacks encryption or compliance with HIPAA/GDPR. Many viewers are not FDA-cleared for diagnostic use, limiting clinical applications. Additionally, they may not scale well for large organizations, and some platforms have a learning curve for new users. Selecting the right viewer depends on your specific functionality, security, and integration capabilities needs.

• No software installation required
• Cross-platform compatibility (Windows, macOS, Linux)
• Secure local processing of files
• Accessibility from any device with an internet connection

Yes, your medical images are secure as long as the platform processes files locally on your device without uploading them to external servers. Many professional-grade viewers comply with HIPAA and other privacy standards to ensure patient data security. Some platforms include tools for anonymizing sensitive patient information in compliance with privacy regulations.

A stable internet connection and a modern web browser (e.g., Chrome, Firefox) are typically sufficient. Advanced features may require higher hardware specifications. No special hardware is needed; most viewers work on standard devices like desktops or laptops with internet access. Most platforms are compatible with popular browsers like Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge.

Most online viewers support MRI, CT scans, X-rays, PET scans, ultrasound images, and other modalities stored in the DICOM format. Some online DICOM viewers offer advanced features like 3D rendering and MPR (multi-planar reconstruction) for enhanced analysis.

An online DICOM viewer is a web-based application that allows users to view and analyze medical imaging files (e.g., MRI, CT, and X-ray) directly in their browser without installing additional software. The viewer processes DICOM files locally on the device through the browser, ensuring data privacy and security while enabling features like zooming, windowing, and annotations.
