dicom radiology

DICOM3.0 images, produced by medical imaging devices to produce standard medical image images, dicom is widely used in radiation medicine, cardiovascular imaging and radiological diagnosis equipment (X-ray, CT, MRI, ultrasound, etc.), and in the field of ophthalmology and dentistry and other medical fields are more and more widely used. In tens of thousands of medical imaging devices, DICOM is one of the mo

Background:The previous post introduced the Leader/follower thread pool model used in Dcm4chee, the main purpose of which is to save context switching and improve operational efficiency. This blog is the "Dicom Open Source Library multithreaded Analysis" series, highlighting the threadpoolqueue thread pool used in fo-dicom.Threadpoolqueue in fo-dicom:Let's take a look at the custom data structure in the Threadpoolqueue code.

The DICOM file content is defined in Part 3 dicom iod. CT, Mr, Cr, Dr, US, nm, pet, XA and so on have their own content definitions, composed of a common proprietary part (ie and modules.Dicomdir is defined by Part 10. Is a mini variable-length database file structure. In the past, I was handed down to a computer-wise Indian who asked me: isn't the image file format BMP, GIF, Tif, and JPEG? Why do we need

Tags: wado dicom restful API Orthanc DCMTKbackground:The previous blog post simply translated the CodeProject "using Orthanc Plugin SDK to develop Wado plugin" on the Orthanc website. It mentions that Orthanc supports fast queries from the 0.8.0 version, whereas the original Wado request needs to be positioned directly with the rest API in Orthanc. So why did the previous Orthanc have to step up to locate the instance of the Wado request? How is the n

background:Orthanc is one of the best open source software for DICOM and HTTP services found by bloggers, and some of the basic uses of Orthanc were described in the previous sections. Orthanc from the 0.8.0 release of the plugin SDK, through which the Orthanc built-in rest API to implement the Wado service, the following reference to the official website gives a description of how to use the SDK to implement the Wado service, and to update the offici

Preface: As the image storage and transmission of medical imaging equipment is gradually moving closer to the DICOM standard, during our medical image processing process, you often need to write various program modules related to DICOM images to complete your processing functions. It is a huge project to understand the DICOM protocol from the beginning and write

Background:Orthanc is a new DICOM server introduced in this column, with a lightweight, rest-enabled feature that turns any computer running Windows and Linux systems into a dicom server, or Minipacs. Orthanc embedded in a variety of modules, database management is simple, and does not rely on third-party software. So through the analysis of Orthanc source code can learn to build a

downloaded miraculously ".On-site troubleshooting: The figure end and the PACS server have checked the connectivity between the network and the port by Using Ping and talnet commands respectively. Therefore, the network hardware environment can be ruled out. Most of the problems are the DICOM server and graph configuration. The worst is the internal system bug (the most undesirable is the system bug, ^_^ ). First, copy the log files on the PACS serve

there are three categories, based on DCMTK, Java-based Dcm4che, and C #-based fo-dicom (MDCM). Here again Dcm4chee is based on the DCM4CHE14 version, using the ejb2.x technology to develop a DICOM Archiving service framework that relies on JBoss, can be easily understood as an open-source PACs system. There are different maintenance agencies and people for each library, which can result in different versio

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

However, when the DCMSCP class is extended, it is expected that the simulation implements its own Storescp.exe tool when there is a problem, the client prom

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.

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

The format of any image file is composed of two parts: the header of the parameter and the pixel data ).The headers in BMP, JPEG, And Tiff formats only describe the basic parameters of the image, such as the number of rows and columns, the number of digits used for each vertex, whether the image is compressed, and the color palette. Headers are usually fixed in length.Medical Imaging also requires many other parameters, such as basic patient data, basic exam data, series data, and location data.

DICOM (digital Imaging and Communications in Medicine) is the international standard for medical imaging and related information (ISO 12052), which is medical imaging and communication. The following article mainly introduces the python to dicom image reading related data, the need for friends can refer to, the following to see together. DICOM Introduction DICOM

Relying on Mongoose, this lightweight web Server,orthanc is a good implementation of the RESTful API and traditional DICOM service integration, which
