Each learner uses their own computer or other compatible device. Participants can be geographically dispersed and also individually connected. While DICOM standard specifies how 3D and 4D (3D+t) ultrasound volumes can be stored in standard fields, most ultrasound manufacturers do not follow this standard.Virtual training is a facilitator-led, live online learning event that is delivered in a virtual environment. Typically, only 2D screenshots or 2D+t screen capture videos are stored in standard fields. Image3D API can be used to read 3D ultrasound images from GE, Canon, Hitachi, Siemens, and Philips scanners.ģD information is stored in private fields and proprietary algorithms are needed to interpret them. This API is only avaialble on Windows and a reader library must be obtained from the scanner's manufacturer and installed on the system (by registering the reader by running regsvr32 (loaderlibraryname).dll as an administrator). ![]() This API can provide access to all kinds of image data and ECG signal. File can be read by renaming it so that it ends with. 3dus and drag-and-dropping to the Slicer application window. Philips Import Philips 4D cardiac images: GE 3D ultrasound images can be also loaded using the DICOM module (then the files do not have to be renamed).Įxample import of 4D ultrasound sequence and ECG imported from GE system:Īdditional vendor-specific file reading options are described below. Philips machines save 3D/4D ultrasound data in private fields. Method to extract volumetric images from these fields is not publicly disclosed. However, Philips QLAB cardiac analysis software can export images to a DICOM format variant, which stores volumetric images in standard fields, which can be interpreted without proprietary methods. Unfortunately, these DICOM files are not fully DICOM compliant (required fields, such as SOP instance UID, patient name, ID, study instance UID, and series instance UID fields are missing), therefore they need to be fixed up before they can be imported into a DICOM database. Get Philips QLAB cardiac analysis software with "Cartesian DICOM export" option. Your Philips representative can help you with this.Right-click, choose Analyze with Q-App, select any 3D Q-App, i.e., 3DQA, 3DQ or MVN (note that you do not have to Analyze, just open with the application).Go in to preference to check the Cartesian export under system and click OK.Click on the image export icon located in the lower left hand corner (icon: film strip with an arrow).Click on "Save as", scroll down to "Cartesian DICOM (3DDCM)".Click "Enable Cartesian Export" - enter password that a Philips representative provided.Note: Cartesian export does not work on color 3D datasets.Install the SlicerHeart extension and the Sequences extension in Slicer.Use Philips DICOM patcher module in Slicer to make the DICOM file standard compliant and/or directly export to a 4D file in NRRD format.The file in NRRD format can be directly loaded into Slicer by drag-and-dropping to the application window. The fixed DICOM file can be loaded into Slicer using the DICOM module (first need to be imported into Slicer's database and then it can be loaded into the scene). Philips Affinity systems can export acquired 3D ultrasound volumes in DICOM format, but slice spacing is not stored in private DICOM fields (see more information here). If SlicerHeart extension is installed and data is loaded using DICOM module (as described below) then Slicer will retrieve this information from these private fields and the volume will be loaded correctly. To export 3D volumes from your ultrasound system to DICOM, enable 3D export in application settings.Drag-and-drop your image folder to the Slicer application window.In the popup window click OK (to load directory into DICOM database).Click Copy (to make a local copy of the folder into the Slicer database) or Add link (to not copy data files, data will not be available if the original folder is removed).Wait for the import operation to complete, click OK.In the DICOM browser window, select data to load and click Load button.Wait for loading to complete (may take a few minutes).GE machines save 3D/4D ultrasound data in private fields. They can be decoded using Image3dAPI DLL obtained from GE. Loading various 3D/4D ultrasound images using Image3dAPI Some older versions of GE systems, typically used for obstetrics, used a simple file format (KretzFile) which was reverse-engineered and a publicly available importer was created and made available in SlicerHeart. Obtain Image3dAPI loader from GE: sign up to the Edison Developer Program (just filling out a short web form) and wait for GE's response.
