#Sample dicom files how to
“Whoever understands how to do a kindness when he fares well would be a friend better than any possession.” ~ Sophocles However, DICOM files don’t necessarily have to be about images as most people assume and may be used to store other information such as reports, ECG signals and even audio (which we will cover later) as well. Most DICOM files (sometimes seen with a '.dcm' extension - see footnote of this article) usually contain image data, and may sometimes even contain multiple images (or “frames” as they are often referred to in DICOM) to enable what is called a cine-loop which allows a DICOM viewer to visualize the entire sequence of images as a movie. This minimizes the risk of attributing some critical healthcare information to a wrong patient. This dictionary (see page 23 of this document) to get an idea how comprehensive it is) which contains several thousand of these tags helps us encode information such as when and where the image was taken, who it belongs to, referring physician and even diagnosis information along with core image data. However, the information stored in the DICOM file is far more structured and diverse than other standards in the form of a DICOM Dictionary. Please keep the official DICOM standard document at this link handy as many things I cover in this tutorial are explained in more detail there.Īs you recall from my introductory DICOM tutorial, a DICOM file often contains image data and data about the patient in the same file using the concept of tags (to be explained later) like other image formats such as TIFF.
#Sample dicom files series
I thought I will start this programming tutorial series on DICOM with an very high-level introduction to the DICOM file format. Please note that this tutorial assumes that you know C# (or any equivalent object-oriented language such as Java or C++). Before we get started on this tutorial, have a quick look at my earlier article titled “Introduction to the DICOM Standard” for a short and quick introduction to the standard. This is part of my series of articles on the DICOM standard.
