How DCM4CHEE stores the bits allocation information of DICOM image

由 混江龙づ霸主 提交于 2020-01-16 19:19:46
问题 We are using DCM4CHEE as replica of PACS server. I have 8 bit and 16 bit images spread across multiple studies. All the images are stored in DCM4CHEE. We are running DICOM DUMP [DCM2TXT] on sample images to identify the bits allocation. It is a lengthy process. Does DCM4CHEE server stores the bits representation in DB?, if so where can I find the information about the bits allocated? Please help me in finding the best solution for this. Thanks, -Anil Kumar.C 回答1: Yes, it is in the database

问题 I'm trying to display a DICOM image in opencv-python.I am using the pydicom library,And then adding API's to create a full fledged DICOM viewer with DOTNET, that runs python(C# calls python with process instance of course!!). I am unable to convert or see the uncompressed DICOM image. whenever i try to load or modify the pixel_array. I get error messges. import dicom import cv2 import numpy df=dicom.read_file("IM-0001-0002.dcm") df.pixel_array Traceback (most recent call last): File "<pyshell

Swagger Yaml schema definition for object without a fixed property list

问题 I am implementing an API-first application with the help of Swagger. One of the most important objects to be returned is a DICOM object, which returns a collection of attributes with flexible names, for example: { "00080005": {"vr":"CS","Value":["ISO_IR 100"]}, "00080020": {"vr":"DA","Value":["20160602"]}, "00080030": {"vr":"TM","Value":["171855.7490"]}, "00080050": {"vr":"SH","Value":["1234"]}, "00080090": {"vr":"PN","Value":[{"Alphabetic":"Parikh MD^Anush^M"}]} } So I cannot know the name

Correct display of DICOM images ITK-VTK (images too dark)

由 风格不统一 提交于 2020-01-14 10:45:08
问题 I read dicom images with ITK using itk::ImageSeriesReader and itk::GDCMImageIO after reading i flip the images with itk::FlipImageFilter (to get right orientation of the images) and convert the itkImageData to vtkImageData using itk::ImageToVTKImageFilter. I visualization images with VTK using vtkResliceImageViewer in QVTKWidget2. I set: (vtkResliceImageViewer)m_imageViewer[i]->SetColorWindow(windowWidthTAGvalue[0028|1051]); (vtkResliceImageViewer)m_imageViewer[i]->SetColorLevel

How to save image as DICOM

由 試著忘記壹切 提交于 2020-01-13 10:36:29
问题 I need to save JPEG image as a DICOM using c# and some free library. I read a lot of topics where it was described how to do the opposite, but I couldn't find anywhere how to perform what I need. The best I could achieve is to save image using ClearCanvas, but it gets distorted. DicomFile dicomFile = new DicomFile(); dicomFile.MediaStorageSopClassUid = SopClass.DigitalXRayImageStorageForPresentation.Uid; dicomFile.DataSet[DicomTags.SopClassUid].SetStringValue(SopClass

how to display dicom image in matlab?

由 青春壹個敷衍的年華 提交于 2020-01-12 07:12:50
问题 I want to ask about this function in matlab dicomread example : a = dicomread ('m.dcm'); imshow(a) the image showed in the screen but it is very dark.....I wonder way it is dark and not normal. I checked with different dicom images but the problem remain. I hope you can help me and thanks in advance. 回答1: If you are dealing with monochrome images, you can set a linear scaling between a minimum and maximum pixel value as follows: img = dicomread('filename'); imshow(img, [minAllowedPixValue

Digital Imaging and Communication in Medicine DICOM 3.0 DICOM是Digital Imaging and Communications in Medicine的英文缩写，即医学数字成像和通信标准。是 ACR （American College of Radiology,美国放射学会）和NEMA（National Electrical Manufactorers Association,国家电子制造商协会）为主制定的用于数字化医学影像传送、显示与存储的标准。在DICOM标准中详细定义了影像及其相关信息的组成格式和交换方法，利用这个标准，人们可以在影像设备上建立一个接口来完成影像数据的输入/输出工作。 DICOM标准以计算机网络的工业化标准为基础，它能帮助更有效地在医学影像设备之间传输交换数字影像，这些设备不仅包括CT、MR、核医学和超声检查，而且还包括CR、胶片数字化系统、视频采集系统和HIS／RIS信息管理系统等。 该标准1985年产生。目前版本为2003年发布的 DICOM 3.0 2003 版本。 DICOM 发展历史 1982 - ACR和NEMA联合成立了一个委员会，制定DICOM标准。 1985 - 公布1.0版本(ACR-NEMA V1.0)。 1988 - 公布2.0版本(ACR-NEMA V2.0)。
