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

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

delimiter (the label of an object in the DICOM protocol is in four-byte format, As 0x0002 0010 represents the Transfersyntax UID). The colorful and changeable information world originates from different interpretation standards or interpretation rules. So learn the standards and understand the actual application scenarios.Text files and binaries can be understood as 01 sequences that apply different standard stores, and text files mean that all infor

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

Dicom vr data type table Luo chaohui (http://www.cnblogs.com/kesalin) This article follows the "signature-non-commercial use-consistency" creation public agreement The DICOM Standard defines 27 Basic Data Types in ps3.5, namely the value representation (VR, value representations ). Value representations are used to encapsulate all possible clinical data types. Writing anything in

Simple sample code for creating a DICOM dataset and keeping it to a file: Char uid [100];Dcmfileformat fileformat;Dcmdataset * dataset = fileformat. getdataset ();Dataset-> putandinsertstring (dcm_sopclassuid, uid_secondarycaptureimagestorage );Dataset-> putandinsertstring (dcm_sopinstanceuid, dcmgenerateuniqueidentifier (UID, site_instance_uid_root ));Dataset-> putandinsertstring (dcm_patientname, "doe ^ John ");......Dataset-> putandinsertuint8arra

Background:in making a dicom Web Service, where Wado-rs needs to parse Transfersyntax, then it uses the Dicomfile.changetransfersyntax method in fo-dicom. code similar to:var df = dicomfile.open (SamplesDir + @ "\user submitted\overlays.dcm");df = df. Changetransfersyntax (dicomtransfersyntax.jpeg2000lossless);Problem:The above code is working properly in the console (EXE) and throws an exception in the WEB

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

. Although the bottom of the computer is stored in binary format, we are able to customize different interpretation standards. the same 0 and 1 sequences. interpreted in different ways. The meaning of the expression is different . In fact, the use of different standards to interpret the same sequence of phenomena in the computer field is not common. In a 32-bit machine, the same four-byte 01 sequence. May represent an unsigned integer or a signed integer (in the C + + language) or an IP address

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

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
