Background:Radiotherapy is a complex process that requires multiple roles involving oncologists, analog location technicians, dosimetry, physiotherapists, therapists, nurses, and more. The whole process involves the imaging system, positioning System, planning system, treatment system, quality control QA system, information management system and other independent subsystems , compared to the conventional medical information system (such as his, RIS, LIS, PACS, etc.) there is a " low degree of in

Tags: Io AR, use SP strong file on, CTI Keywords: DICOM Itk CT unclear window width Fragment: I recently used Itk to read DICOM. Before hearing the task, I didn't even know what Itk and DICOM are. of course, when I first heard the task, I only had the "what is this code? "" What is this code? "... After being disgusted with the progress for a few days, I

1. Data bit storage (dcm_bitsstored), Data bit allocation (dcm_bitsallocated), data symbol type (dcm_pixelrepresentation), grayscale offset (dcm_rescaleintercept) Relationship to the data value (Dcm_pixeldata) itself:(1) dcm_bitsallocated is the number of bytes allocated for each pixel, such as a single byte is 8, two bytes is 16 ...., it is best to use the corresponding dcm_bitsallocated data type to read the DICOM data and save it to the computer me

The DICOM data in the hospital is not easy to copy, so here are some medical data, but not limited to dicom data URLs for everyone to download.Stanford University Body Database (RAW data)http://graphics.stanford.edu/data/voldata/The DICOM data provided by OsiriX is mostly compressed and VTK cannot be resolved by default. Available DCMTK parsinghttp://www.osirix-v

Recently, when processing CT images, CT images scan the human body layer by layer, and there are many unnecessary parts in the image, such as the ribs, as a result, there are many unnecessary parts of the 3D reconstruction image. Very difficult to handle. As a result, I thought of a simple method to set unnecessary pixels to black for a dicom image. Originally intended to be implemented with VC ++ 6.0 + VTK, debugging is too troublesome, it is easy t

This article mainly introduces the Python read the dicom header file instance, has a certain reference value, now share to everyone, the need for friends can refer to Open dicom image with Dicompyler software, header file: Of course, you can read it directly: ds = Dicom.read_file (' h:\data\data\\21662\\2.16.840.1.113662.2.0.105002416.1489146183.701\ct\\ct#0#2

file: dicomdir.rar the compressed file is a sample of two dicomdir files. dicomdir is a micro-database in a tree structure. The file structure of the CD is recorded. the dicomdir tree directory is a special directory structure specified in the DICOM standard, from the top layer to the bottom layer, the thumbnail is the scaled down image. Dicomdir and thumbnails can be used to conveniently and batch Import images to prevent incorrect image op

Background:The DICOM-RT Series blog focuses on the complementary criteria for radiotherapy in the DICOM3.0, namely Dicom-rt. In order to facilitate the follow-up on the dicom-rt of the relevant IoD, SOP concept of understanding, the column has recently done radiation-related knowledge points of popularization.PS: Of course, I am not a radiation professional, the

Transferred from: http://www.cnblogs.com/assassinx/p/3649103.htmlLook at the standard more and more paste, the root cause: Dicom abstraction is very serious, is "expert" to get. No way.What is the service class is what SOP, I believe you see the DICOM standard head most do not know how to start. It's not the socket, it's hard. First you have to understand that God is called PDU, from the PDU, I can only say

The more you look at the standard, the more obscure it is. The root cause is that dicom is very abstract, which is obtained by "experts. No way. What kind of service is and what kind of sop, I believe you don't know how to start with the dicom standard. Isn't it socket? How hard is this. First of all, you have to understand that the magic horse is called a pdu. Pdu is the pdu protocol data unit. You can un

The Unit of CT value is Hounsfield, referred to as Hu, the range is-1024-3071. It is used to measure the absorption rate of X-rays in human tissues, and to set the water absorption rate at 0Hu.In the dicom image reading process, we will find that the pixel value of the image may not be this range, usually 0-4096, which is the pixel value we often see or grayscale value, which requires us to the image pixel value (gray value) into the CT value.First, y

Background:The representative of GIT and GitHub as a distributed version control system has become the preferred version Control tool for most developers. Because of its different and SVN centralized version management, so in a slightly different way to work together, let's compare and analyze (here in my DICOM3.0 standard Chinese version of open source books, for example):Merge others ' GitHub repositories (merge other's Repo on Github): 1.
