dicom

I would like to read a DICOM file in C#. I don't want to do anything fancy, I just for now would like to know how to read in the elements, but first I would actually like to know how to read the header to see if is a valid DICOM file . It consists of Binary Data Elements. The first 128 bytes are unused (set to zero), followed by the string 'DICM'. This is followed by header information, which is organized into groups. A sample DICOM header First 128 bytes: unused DICOM format. Followed by the characters 'D','I','C','M' Followed by extra header information such as: 0002,0000, File Meta Elements

In C++ I want to read individual pixel values from DICOM images. There are in fact quite a few free libraries. If you prefer a higher-level COM envelope and are willing to purchase it, there are a few others - I'm familiar with RZDCX and DicomObjects , and googling around will get you some others. It's reasonably easy to access pixel values under the free DCMTK. If you want the raw Hounsfield data look here , and if you need the post-LUT (e.g., windowing) values - you can use DicomImage::getOutputData . There this library: http://dicom.offis.de/dcmtk If you're using x86 or x86_64, then the

If we convert a DICOM image to JPEG, what is the way to translate / calculate Image width = 500, Window Level = 2000 of the original DICOM to JPEG's brightness and contrast? There's no direct answer to your question, since DICOM and JPEG have different ways to define brightness/contrast. JPEG stores true color values (RGB), while DICOM have raw pixel values, uncolored most of the time. A DICOM viewer renders it by reading the Window Level and Width and convert this to color. That is, you can say that you want your JPEG to have its pixel colors as if it was rendered by a viewer. In your case

I can set the attributes and create the dicom file, but I can not write the image to the dicom file? I've tried it with an image I have and it works but I expect it won't work for RGB images. Something like this though BufferedImage jpg = ImageIO.read(new File("myjpg.jpg")); //Convert the image to a byte array DataBufferUShort buff = (DataBufferUShort) jpg.getData().getDataBuffer(); short[] data = buff.getData(); ByteBuffer byteBuf = ByteBuffer.allocate(2*data.length); int i = 0; while (data.length > i) { byteBuf.putShort(data[i]); i++; } //Copy a header DicomInputStream dis = new

How we can convert a dicom file(.dcm) to a jpeg image using java? Here is my code: import java.io.File; import java.io.IOException; import org.dcm4che2.tool.dcm2jpg.Dcm2Jpg; public class MainClass { public static void main(String[] args) throws IOException{ Dcm2Jpg conv = new Dcm2Jpg(); conv.convert(new File("C:\\Users\\lijo.joseph\\Desktop\\Dicom\\IM-0001-0001.dcm"), new File("C:\\Users\\lijo.joseph\\Desktop\\Dicom\\IM-0001-0001.jpg")); } } and i am getting the following error while running the project Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli

I have used DICOM using MERGECOM when I was in GE Healthcare in 2005. After that I don't have much knowledge in the DICOM system. Now we have a requirement for implementing PACS system using .NET platform. Can you recommend a decent, good, community supported .NET based DICOM library or framework? or Do you know any commercial libraries for DICOM which support .NET? The ClearCanvas library is a good option. I'm a bit biased because I work on it, but its actively maintained, is used by a number of commercial products, and is used by the other ClearCanvas products. The ClearCanvas products are
