![]() GE machines save 3D/4D ultrasound data in private fields. Wait for loading to complete (may take a few minutes).In the DICOM browser window, select data to load and click Load button.Wait for the import operation to complete, click OK.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).In the popup window click OK (to load directory into DICOM database).Drag-and-drop your image folder to the Slicer application window.To export 3D volumes from your ultrasound system to DICOM, enable 3D export in application settings. 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. 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). 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). The file in NRRD format can be directly loaded into Slicer by drag-and-dropping to the application window. 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.Install the SlicerHeart extension and the Sequences extension in Slicer.Note: Cartesian export does not work on color 3D datasets. Click "Enable Cartesian Export" - enter password that a Philips representative provided.Click on "Save as", scroll down to "Cartesian DICOM (3DDCM)".Click on the image export icon located in the lower left hand corner (icon: film strip with an arrow).Go in to preference to check the Cartesian export under system and click OK.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).Your Philips representative can help you with this. Get Philips QLAB cardiac analysis software with "Cartesian DICOM export" option. 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. 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. Method to extract volumetric images from these fields is not publicly disclosed. Philips machines save 3D/4D ultrasound data in private fields. 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. 3dus and drag-and-dropping to the Slicer application window. File can be read by renaming it so that it ends with. This API can provide access to all kinds of image data and ECG signal. 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). Image3D API can be used to read 3D ultrasound images from GE, Canon, Hitachi, Siemens, and Philips scanners. 3D information is stored in private fields and proprietary algorithms are needed to interpret them. Typically, only 2D screenshots or 2D+t screen capture videos are stored in standard fields. 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.
