dicom

I am looking forward to visualize a 3D matrix into matlab from dicom files. As I am not quite familiar with matlab, i managed to get help from this post : The difference is that my matrix is not made of 1 and 0 but negative numbers that are correctly red with imshow(dicomeread(dicomFile)) How can I get to the same contrast but with a 3D rendering ? My code : dicomFilesZm = dir(fullfile(myDcmFolder, 'SLZ-*.dcm')); %Get files name dicomFilesZp = dir(fullfile(myDcmFolder, 'SLZ+*.dcm')); %~ Z = dicomFilesZm(end:-1:1); % sort dicomFilesZ = [Z ; dicomFilesZp]; % recompose final array with files name

主要原理：调整dicom的窗宽，使之各个像素点上的灰度值缩放至[0,255]范围内。 使用到的python库：SimpleITK 下面是一个将dicom（.dcm）图片转换成jpg图片的demo： import SimpleITK as sitk import numpy as np import cv2 def convert_from_dicom_to_jpg (img , low_window , high_window , save_path): lungwin = np.array([low_window* 1. , high_window* 1. ]) newimg = (img-lungwin[ 0 ])/(lungwin[ 1 ]-lungwin[ 0 ]) #归一化 newimg = (newimg* 255 ).astype( 'uint8' ) #将像素值扩展到[0,255] cv2.imwrite(save_path , newimg , [ int (cv2.IMWRITE_JPEG_QUALITY) , 100 ]) if __name__ == '__main__' : # 下面是将对应的dicom格式的图片转成jpg dcm_image_path = '/DICOM_image/lung001.dcm' #读取dicom文件 output_jpg

I'm in need of some sample DICOM files that I can use to test out multiple overlays. I have looked everywhere, maybe i'm not searching for the right thing idk, but could anybody help me with this?? The real reason I want the DICOM files is to better understand the Overlays data structure hands on... I need to examine the files. Links to sites would be appreciated. This link answered my question for the most part as I needed to just understand something about overlay grouping. http://www.medicalconnections.co.uk/wiki/Number_of_Overlays_in_Image 来源： https://stackoverflow.com/questions/4939364

I have a DICOM image loaded as a matrix in matlab. My question is, how do I show specific slices of that image in each orthogonal direction? Like view slice x at position 100, y=0, z=0 If your matrix is M, and has d dimensions (3, or what have you) and you want to plot a 1-D "slice" of one of the dimensions then: plot(squeeze(M(n1,n2, ...,:,...)); where n1,n2,... are the positions of dimension x,y,... where you want to slice, and the operator (:) is the dimension you want to plot. for example, given a 5 dimensional matrix M=rand(10,10,10,10,10), lets slice the 4-th dimension around some points

I have to pick all valid DICOM Files from folder. I can recursively pick all the files from the folder which have *.DCM extension. But any file with *.DCM also picked up and such file is not valid DICOM File. What is best way. I thought of reading few byte of the file and validating. Or Any Other Method or any other EXEs we have which validates. Thank you, Harsha Edit: Solution for the problem: I finally used the dcmftest.exe for verification. Hope I am on right track. -Harsha Validating a DICOM file is not as easy task considering the different mandatory and optional tags present in different

I started working in a new project with a big challenge. I am working in a medical project and in that I have to read DICOM images and process the image with its properties. I gathered some basic knowledge on DICOM and PACS. As I worked on WPF around 2 years of my career so I choose to do this project using C# and WPF. I googled a lot and even I went through many articles in SO and also in codeproject, every where I found they used some libraries/ third party tools like: gdcm , LEADTOOLS , ClearCanvas Can any body suggest me any alternate way of doing DICOM Image processing without using any

We are writing an importer for dicom files. How does one generally deceide if a series of images forms a 3D-Volume or is just a series of 2D images? Is there a universal way to decide this for most vendors? I looked a the DICOM tags and could no find an apparent solution. The DICOM standard defines UIDs for describing the hierarchy. These are from top to bottom: Study UID - Identifier of the study or scanning session. Series UID - The same within a series acquired in one scan. Image UID - Should be unique for any image. A DICOM image saved by a standard-conforming implementation should have

I'm currently trying to make an android dicom app Following code opens pictures drom res/drawable in "ussual" image formats, but it doesn't work with .dcm public class BitmapView extends View { public BitmapView(Context context) { super(context); } @Override public void onDraw(Canvas canvas) { Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.test); canvas.drawColor(Color.BLACK); canvas.drawBitmap(bmp, 10, 10, null); } } in the main activity: protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new BitmapView(this)); }
