What is DICOM?
DICOM, which stands for Digital Imaging and Communications in Medicine, is a standardized format that enables medical professionals to access and share medical images regardless of their location or the devices they use. DICOM images require specific software known as DICOM viewers to read and display the format. These images are typically stored in a large database called the Picture Archiving and Communication System (PACS), along with corresponding patient data. The purpose of a DICOM application is to store information about the imaging examination and patient details in the PACS, and then retrieve and interpret (and potentially edit) medical images when needed. DICOM images are unique in that they contain both image data and patient information.
DICOM viewers are essential tools for medical professionals to view and analyze medical images in DICOM format. They offer a range of features to make it easier to interpret medical images, such as zooming, panning, measurement tools, and more.
DICOM viewers can securely share medical images and patient information with other medical professionals, allowing remote access to patient images and information. Overall, DICOM viewers play a critical role in accurately diagnosing and treating medical conditions based on medical images.
Open-source DICOM Viewers
There are many DICOM viewing software options available, with a variety of features, pricing plans, and add-ons. This can make it challenging for healthcare professionals to select the best software for their needs. In this article, we aim to make this decision easier by presenting some popular DICOM viewers with useful features and very affordable pricing plans. Most of these viewers are even available for free for basic use.
