How to get an image from a given dicom file using clearcanvas libraries in c#

问题 Can you please help me in extracting image(binary data) from a dicom file. 回答1: The question is not completely clear. If you want a bitmap for display purposes, then this is basically a duplicate of this question. Please see the accepted answer. If you are just trying to extract the pixel data into a byte array, then you can use code like this: DicomFile theFile = new DicomFile("c:\tmp.dcm"); theFile.Load(); byte[] thePixels = theFile.DataSet[DicomTags.PixelData].Values; 来源： https:/

How can I read and write DICOM images in MATLAB version 7.0?

由 你。 提交于 2019-12-11 03:28:30
问题 I am currently using MATLAB version 7.0. I need to read a DICOM image and write it back out. What functions are available to help me do this? 回答1: You can use the dicomread/dicomwrite functions from the Image Processing Toolbox, but I'll recommend using one of the many functions found in the file exchange. Personally, I use this. 回答2: Look in the code at the bottom of this page http://sites.google.com/site/dicomil/dicomandmatlab 来源： https://stackoverflow.com/questions/5052620/how-can-i-read

Encode JPG image file as DICOM PixelData using ClearCanvas

由 喜你入骨 提交于 2019-12-11 02:43:23
问题 I have a set of JPG images that are actually slices of a CT scan, which I want to reconstruct into DICOM image files and import into a PACS. I am using ClearCanvas, and have set all of the requisite tags (and confirmed them by converting one of my JPG files to DICOM using a proprietary application to make sure they are the same). I am just not sure how I should be processing my JPG file to get it into the PixelData tag? Currently I am converting it to a Byte array, on advice from ClearCanvas

Create DicomImage from scratch using Dcmtk

由 二次信任 提交于 2019-12-11 01:28:44
问题 In order to save CT data I would like to create a DicomImage from scratch, similar like this can be done using DRTImageIOD . However, DicomImage does not have a default constructor. From the documentation it looks like the constructor can only load existing data. Is it possible to use DicomImage directly, or is going low-level through DcmFileFormat the only viable approach? (I am using Dcmtk 3.6.1) 回答1: As you can read in the documentation, the purpose of the DicomImage class is visualization

问题 I am using GDCM to read in DICOM images. Is there an easy way to read in a dicom file with GDCM, and then convert it to a Java BufferedImage? So far I have the following String filename = "C:\\test.dcm"; gdcm.ImageReader reader = new gdcm.ImageReader(); reader.SetFileName(filename); reader.Read(); gdcm.Image image = reader.GetImage(); BufferedImage bufferedImage = new BufferedImage((int)image.GetRows(, (int)image.GetColumns(), BufferedImage.TYPE_USHORT_GRAY); // How do I populate
