Please note: Splitting is only allowed for Coverage mode anatomical. Dot Cockpit and Strategies Learn how to proceed to the Dot Cockpit The Whole-Body Dot Engine can be configured in the Dot Cockpit. This video demonstrates how to access the Dot Cockpit icon and navigate to the Whole-Body Dot Engine. In addition, the two strategies standard and motion-insensitive are briefly shown.   Prerequisites for running the Whole-Body Dot Engine: Patient Positioning (HF/FF), Coil positioning depending on needed coverage (HeadArray, Spine Array, PeripheralAngioArray) Successful Patient registration, automatic loading of the Whole-Body Dot Engine to the measurement queue selected The Patient View is open In the Patient View, you can select General (e.g. Scanning strategy), breath-hold parameters, coverage parameters and the Focus region. Parameters of the Patient View Learn more about the parameters of the Patient View Base ImageHotspotsText BlocksImage FileFocus Adaption provides three different options: None: No protocol adaption will be performed, only positioning is assisted. AutoCoverage: FOV, slice coverage, and positioning are automatically adapted. BH+ AutoCoverage: In addition to AutoCoverage, the protocol is adapted to the patient's breath-hold capability.Exam Strategy: two options are available for the patient: Standard: Measurements are performed with the single and multi-breathhold techniques. This approach is optimized for high image quality in short exam times. Motion-insensitive: For uncooperative/moving patients, motion-insensitive protocols are used. They are more robust than Standard protocols, but require longer scans.  Auto Bolus Detection: Select this check box, if you want automatic detection of contrast bolus arrival and fully automatized dynamic scan for the focus region. Please note: This option is only available if the focus region Abdomen is selected.Auto ROI: Select this check box if you want the system to perform automatic positioning for the CareBolus ROI. Please note: This option is only available if the focus region Abdomen is selected.Breath-Hold Capability: Specify the Breath-Hold Capability of the patient.  The Breath-Hold Capability depends on what health conditions the patient has. Therefore, the Breath-Hold Capability can be individually adapted to a patient´s conditions.Auto Breath Hold Commands: Select this option if you want breath-hold commands to be played automatically throughout the entire examination.Pause Between Breath-Holds: Select a language for the breath-hold commands, the pause between breath-holds and pause before the first breath-hold.Coverage Slider: To select a continuous range that determines the coverage scan to be measured in a multi-region examination by moving the Coverage slider.Focus: Select Focus to specify which region should be examined. With additional high-resolution protocols. Please note: Only one focus region can be selected. In the Dot Cockpit, you can configure the protocols for each individual focus region.Fast View: Select the FastView option to extend the FastView range for coverage of the legs.

No interaction from the user site is required. The FastView localizer executes automatic breath-hold commands and the duration normally exceeds the breath-hold capability of the patient. As a result, the "Continue breathing" command will be automatically given after the configured breath-hold capability. At the completion of the FastView localizer, the resulting images are loaded into the GSP. Based on the FastView data, the system performs automatic segmentation of the anatomical regions chest, abdomen, and pelvis.   Automatic inline segmentation Learn more about automatic inline segmentation Tab TitleTextChest With the FastView data, automatic segmentation of the anatomical regions is performed. The calculated volumes or organ boxes visually propose the scan area for the three body regions chest (chest_small, chest_large), abdomen and pelvis. The organ boxes define the positions and field of views of the subsequent measurements. The organ boxes are calculated based on the landmarks detected, as shown in these examples. chest_small                  chest_large                 Abdomen With the FastView data, automatic segmentation of the anatomical regions is performed.

The Field-of-View (FOV) is adjusted to properly cover the anatomy.The FOVs for the different regions are always aligned and set to the maximum. FOV in the read and phase direction is propagated. Coverage modes Learn more about Coverage modes Tab TitleTextanatomical In anatomical Coverage Mode, measurement volumes are adapted according to the segmented anatomical regions, with different sizes in the H-F direction. Examples for anatomical coverage mode Coronal     Sagital     Splitting within a region is perfomed if the configured maximum extension along the H-F direction is exceeded and splitting is allowed for this region.  uniform Uniform Coverage mode is characterized through equal measurement volume sizes in the Head to Foot direction. This coverage mode is more suitable for whole-body diffusion scans. Examples for uniform coverage mode include coronal planes sagital planes      The separation of the measurement volumes according to the different regions is not relevant: the system determines the optimal size and the minimum number of individual measurement volumes needed to cover the selected anatomy. No splitting is available for the uniform coverage mode.   Measurement queue How to repeat a sequence in the measurement queue Hint:  If the image quality of a specific coverage station is poor (due to patient movement, suboptimal breath-holding, …),  measurements can easily be repeated by adding them again to the measurement queue. Have a look at the video to see how it works.   Performing focus region scans is optional. Dynamic scans for lesion characterization are depending on the selected focus region: Focus chest: coronal T1-weighted VIBE-TWIST sequence Focus abdomen: liver dynamics with ABLE workflow Focus pelvis: transverse T1-weighted VIBE and TWIST sequence In order to perform focus region scans, a single focus region (such as Chest, Abdomen or Pelvis) can be selected. If necessary, at the end of the Whole-Body workflow and after a contrast injection, a multi-stage T1-weighted measurement will be performed as described above. Examples of focus scans Examples of focus scans Displayed are some examples of focus scans in the regions of the chest, abdomen and pelvis*.  *images were acquired on volunteer. Focus Chest (T1_VIBE, axial)   Focus Abdomen (T1_VIBE, axial)   Focus Pelvis (T1_VIBE, axial)   If contrast media was administered, optional post contrast coverage scans can be performed.                         Since the Whole-Body Dot Engine has two possible strategies, Standard and Motion-insensitive, please remember that the selection of the post contrast protocol will be different for each strategy.

You have completed the Whole-Body Dot Engine Online Training course. Listed below are the key points that have been presented. Take time to review the material before you proceed to the final quiz.   Concept of the Whole-Body Dot Engine   The Whole-Body Dot Engine enables you to combine multi-regions scans covering the regions chest, abdomen, pelvis, and extensions towards the head and legs with contrast enhanced examination of focus scans. The Whole-Body Dot Engine comprises typical workflows: Completing the Whole-Body Dot Engine Patient View Performing the FastView Localizer Performing coverage scans Performing scans in the selected focus region (optional) Performing postcontrast coverage scans (optional) Please note that some of the workflows are optional.   Benefits of the Whole-Body Dot Engine   The Whole-Body Dot Engine provides workflow support (e.g. for fast, robust and standardized multi region MR examinations, for reading or for adaption to patients breath-hold capability or breathing characteristics). Key features of the Whole-Body Dot Engine are step-by-step user guidance, AutoCoverage, AutoTiming, Auto segmentation, the combination of multi-regions scans and preconfigured protocol parameters. In addition, the Whole-Body Dot Engine can be tailored to meet site-specific requirements. Steps of the Whole-Body Dot Engine   Several prerequisites are necessary to run the Whole-Body Dot Engine: the right positioning of the patient (HeadFirst/FeetFirst) and the coils depending on needed coverage (Head Array, Spine Array, Peripheral Angio Array) the successful patient registration and automatic loading of the Whole-Body Dot Engine to the measurement queue selected the Patient View is open The completion of the Patient View covers the first step. In the Patient View, you can select General (e.g. Scanning strategy), breath-hold and coverage parameters as well as the Focus region. After setting up the Patient View, the measurement of the FastView localizer starts automatically and is the second step of the Whole-Body Dot Engine. The FastView localizer executes automatic breath-hold commands. In the third step coverage scans are performed. Two Coverage Modes are available: anatomical and uniform. The coverage modes define how the anatomy will be covered for the measurement step and can be adapted manually. To perform scans in the selected focus region is the fourth step and optional. Dynamic scans for lesion characterization are depending on the selected focus region. The fifth step considers the performance of postcontrast coverage scans and is optional. To perform postcontrast coverage scans, contrast media needs to be administered. Please remember also that the Whole-Body Dot Engine has two possible strategies: standard and motion-insensitive. Based on the selected strategy, the post contrast protocol will be different.   Dot Cockpit and Dot-Add in Configurator of Whole Body   You can configure the measurement step in the tab “Whole Body” of the Dot-Add in Configurator. In addition further configurations with regards to Series Label, Auto Load, MPR Planning etc. can be made.
