MI Segmentation and Contouring - USA

As MI General is intended for the image interpretation of NM, SPECT, SPECT, CT, PET CT and PET Mr. procedures, it also provides tools for segmentation and contouring through the tool gallery the. Anatomy segmentation tool allows you to automatically segment multiple organs. This is. Possible within an anatomical or fused image segment displaying CT data. The Voyciconter tool allows you to segment the volume of interest on 3D image data based on the defined threshold value. The Lesion Scout tool can be used to automatically detect and segment regions of high radio pharmaceutical uptake. It works with PET or 3D. Tomographic expect studies. Please keep in mind that the user interface may differ slightly on different host systems. Automatic anatomy segmentation of multiple organs can be done in CT images or fused functional CT images. Click the Anatomy Segmentation icon from Favorite Tools. The Anatomy segmentation window displays the list of organs available for segmentation. Please note the organs that can be segmented depend on your product license. Please contact your local Siemens Health and Ears Representative to purchase a. Each organ is assigned a color to help distinguish between organ contours. You can choose the color of the segmented organ contour in the preview. Simply click the color box adjacent to the organ specified in the list. Choose. A color from the list of predefined colors. Then select the checkbox adjacent to the organs you wish to segment and click OK. Auto contouring starts. It runs in. The background and the tool is disabled. During this time, you can continue with further evaluation of your study after. Finalization The checked organs are segmented and the contours are displayed in the selected color. In addition, the evaluation results, volume and cubic centimeters are displayed in the Findings panel. You can use the nudge tool and or the Edit Segmentation tool to refine the segmentation boundaries. Note that activities performed on the contours will be reflected simultaneously in all loaded images. You can include additional body regions. Add the required body regions to the list from the Add Body Region drop down menu available at the bottom of the Findings panel. To start with the contouring, select an image segment which contains 3D PET or spec data. From Favorite tools, select. VOI ISO contour. The mouse pointer will change its shape to navigate click. The lesion you would like to quantify. The scroll wheel can be used so that the mouse pointer does not move off the lesion of interest. Click and drag the mouse until the sphere has the desired size, then. Release the mouse button alternatively to encompass an ellipsoidal lesion. Press and hold the shift key and click and drag the mouse over the lesion. The contour of the segmented region is marked in a specific color. The lesion findings are displayed providing values for the Max peak and threshold. The VOI is drawn using the selected threshold value. By default it is 40% unless defined differently by the user. Adjust the threshold as required. The measurements created are also. Saved in the Findings panel to edit what is. Displayed in the findings. Right click. VOI isa contour. Then click VOI Isocontour Properties. Properties now include the ability to configure the default threshold as well as which metrics are quantified. Select or adjust the. Relevant options and then click OK. The Lesion Scout tool helps you to automatically detect and segment regions of high radio pharmaceutical uptake. Select lesion Scout Segmentation from Favorite Tools If the selected lesion Scout preset includes persist criteria, the tool requires a liver or aorta persist reference region in. Case it has not yet been generated, the Lesion Scout tool prompts you to generate the region via the appropriate icon. Select the liver icon or the aorta icon to generate the persist reference region. Lesion Scout now generates a preview image and. Displays all segmentations. Click to accept the segmentations the. Evaluation results are displayed in the Findings panel. To change the presets or the properties of the tool, right click on Lesion Scout Segmentation. To learn the full handling of the tool, watch the single via VB50MM ONCO Lesion Scout Eclip the. Findings Assistant is divided into body parts. The findings are shown under the appropriate body part or subregion. The VOY isocontours and Lesion scout results are automatically localized to surrounding organs. Details at the organ level show derived quantification calculated from the lesions that are located within that organ, values quantified. From the organ segmentation are also shown. Tumor burden metrics are summarized at the organ level in the findings details.
