Secular equilibrium occurs when the number of atoms of a daughter isotope essentially becomes constant after some time. It occurs when the parent half life is much longer than the daughter half life. The following are different ways to look at the physical phenomenon of secular equilibrium in radioactive decay.
When a DICOM file is read and if the encoding is not explicit VR style, the computer is at the mercy of its DICOM dictionary to look up the VR type of each element. If the dictionary is not complete, or if private tags are being read, this can pose a problem. Evil DICOM still reads the elements, but categorizes them into Unknown VR types and stores the data as a list of bytes.
Sometimes when working with 3D graphics in C# or WPF, it is handy to read in and write out common 3D formats to open in programs like MeshLab, Blender, or one of the Autodesk Suite. With the use of some LINQ and lambdas, I was able to whittle down some code to the bare minimum of reading vertices and faces out of an Wavefront .OBJ file. Read More
This is an introduction to how to get setup with Evil DICOM in Visual Studio and how to do some basic operations. It is intended for new users of Evil DICOMM and also new programmers interested in processing the medical format.
I have posted a video to show how to use ESAPI (Eclipse Scripting API) from within Windows Forms. It is a beginner video if you are just getting started with the framework.
When using open air ion chambers for radiation measurements, it is well known that temperature and pressure correction is needed to account for the varying air content (available for ionization) as compared to calibration conditions. In this post I hope to show you some useful tools on how to check your local barometer for accuracy.
I was changing servers last month moving from .NET hosting to wordpress….eesh. Actually I am loving it. I have simplified the getting started documentation. I have been making Evil DICOM stronger and have added some new features that I will blog about in the future. In the meantime, the standard docs are up on the new site. Also, I have moved from the subdomain evildicom.rexcardan.com to rexcardan.com/evildicom. It should forward if you happen to go to the old one, but the new one is the one to be used for the foreseeable future.
