more annotation-related films. Each image has pixel data and zero or multiple overwriting planes. You can specify the value of the print parameter to control the appearance of the film. The print parameters are defined at the film session level, film level, image level, and comment level respectively. The parameter level determines the operation range of the print parameter. For example, the image-level print parameter is valid for the corresponding image. Input to the film session management p

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

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

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

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.

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

DICOM medical image processing: WEBPACS 3. PHP extension skeleton background: In the last two column blogs, we have explained how to build a web pacs environment. if the backend of the platform is not related to DICOM, there is actually nothing to do with PACS, so the last few articles seem to have some run-off questions, but don't worry. the establishment of the development environment itself is a huge and

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

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

Key function: dcmobject * dcmitem: nextincontainer (const dcmobject * OBJ), which is a virtual function in dcmobject and implemented by the dcmitem class. Because the dcmdataset class inherits from dcmitem, therefore, the dcmdataset object can use this method to traverse the tag between 0008-7fe0. The original code of this function is Dcmobject * dcmitem: nextincontainer (const dcmobject * OBJ) {If (!
