![]() Where are radiotherapy contours saved in DICOM?Ĭontours drawn for radiotherapy are saved as DICOM RT Structure Set (“RT” stands for radiotherapy.) in DICOM Standard, and usually as a single file. One of the first extensions was applied to radiation therapy and is known as DICOM-RT. It has also been extended for use in various sub-specialties. The Digital Imaging and Communications in Medicine (DICOM) standard is now widely implemented in radiology as the standard for diagnostic imaging. Is the DICOM standard used in radiation therapy? Examples include the exchange of images for a publication and mailing a patient imaging study for remote consultation. It turns out that the easiest approach to fill this contour is simply draw a filled polygon and cast that into a boolean 2D array.ĭICOM standardizes a common file format, a medical directory, and a physical media. Luckily, the DICOM-RT file exported by treatment planning systems preserve the “connectivity” between the points, that is, they are saved consecutively either clockwise or counter-clockwise. Select the images to be exported - All images, Marked images, or Specific images. The Export as DICOM Images dialog appears. Right-click the data you want to export in the Data Properties and Settings panel and then choose Export > As DICOM in the pop-up menu. How Can Patients Send Physicians an Existing DICOM Medical Imaging Study? This enables patients to electronically send their images to physicians in distant locations who are then immediately able to view and diagnose conditions from their cloud picture archiving and communications system (PACS). Select JPEG Format as the save as type.In the Save As window box, select the location you wish to save the image to.Click on the Image so it is highlighted.To read a group of DICOM files that contain a series of images that comprise a volume, use dicomreadVolume. X = dicomread( filename ) reads the image data from the compliant Digital Imaging and Communications in Medicine (DICOM) file filename. What is the command used to read DICOM images?ĭescription. By extracting data from these tags one can access important information regarding the patient demographics, study parameters, etc. The information within the header is organized as a constant and standardized series of tags. What is DICOM file format?Ī DICOM file consists of a header and image data sets packed into a single file. You can either send them as an email attachment or copy them to a pen drive or an external hard disk and hand that over to the desired recipient. Sharing a batch of snapshots in the JPEG format or Word documents is a fairly simple process. ![]() How can I send a DICOM file?ĭICOM images cannot be shared as you would other files. The focus for this Radiotherapy Structure Set IOD (RT Structure Set IOD) is to address the requirements for transfer of patient structures and related data defined on CT scanners, virtual simulation workstations, treatment planning systems and similar devices.
