myNeedle Guide 3D Workflow Video with myNeedle Laser (USA)

Welcome to the My needle guide 3D workflow video with my needle laser. My needle guide 3D simplifies all interventional procedures with powerful 3D guidance. It enables you to plan and navigate double angulated and multiple needle procedures in 3D. Needle paths can be planned in all three dimensions by interacting with NPR in real time. Switch quickly between patient and path align views, accelerate complex procedures with optional entry point and angle guidance of my needle laser. In this video we will introduce to you how to perform an interventional procedure with my needle guide 3D and my needle laser. Please watch the mind needle guide 2D workflow video to be familiar with the setup of the hardware required for an intervention. We will now start the mine needle guide 3D workflow from the console on the control room on the examination monitor. First register a patient as usual. Then select a desired intervention scan protocol in a dedicated folder. 3 factory protocols comprising 3D in the protocol names are available for interventional procedures. In this video we select the abdomen, 3D intervention, factory protocol, press OK to confirm the selection. The mind Needle Guide software opens on the second monitor. To be able to use my needle laser, you must confirm the first step regarding patient weight information. After the protocol is applied, the patient weighed information will be automatically taken over from the risk or you have to manually enter the patient, wait if this entry is not provided and confirmed, the user can still go on with the workflow. However, my needle laser will just not work if an RCP overlay is used on the table. Also select an appropriate RT overlay. From the dropdown list, this information is needed to compensate for table bending effects. Press the confirm button. For demonstration purposes, we will use an intervention Phantom that is correctly placed on the table. We can now perform a Topa scan. In the 3D workflow and I spiral scan can be used for needle path planning which is already included in the factory protocol. You can also change the scan parameters. For example the dose parameters and slice thickness. Adjust the scan range of the eye spiral to cover the area of interest. Perform the eye spiral scan. The reconstructed I spiral images are automatically loaded into the mind needle guide application on the second monitor. The top row in the second monitor shows that 2D axial segments where thick slice images are displayed as in the mind needle. Guides who D application. In addition, thin slice images are produced and loaded into the NPR segments in the bottom row. If you would like to work with vert images, you can select the 3D plus vert layout from the layout gallery. After selecting this layout and additional vert images displayed in the segment at the bottom row to manipulate the 3D images, you can use the standard 3D interaction functionality's like zoom pan. NPR ref lines to move or rotate the reference lines. And scrolling with the mouse wheel. Or by dragging the right mouse button. You can find more functions in the tools and objects menu. Or you can use the context menu in the 3D segments to select for example switching between different 3D types. Or reset all orientations. Let's keep this 3D plus vert layout and continue with the next step of the 3D workflow. Unlike the 2D workflow, the mind needle guide 3D workflow contains 2 steps in the workflow define path and progress needle. Now we're all set for the first workflow step defined path. You can draw the needle path either on the axial image in the 2D segments or on the Murray mentioned. The 3D segments in this video. We will show it in the 3D segment. Scroll through the axial Mer images to find the lesion. Move the crossing point of the reference line to the target position. Rotate the orange reference line in the lateral NPR image to find the best plane for the needle path. Click the add needle path icon on the workflow header. Please note the first click points of find your target, the second click the entry point for the needle path. This order can be changed in the configuration if needed. Click one time to define the target point. Then drag the line like a rubber band and click a second time on the skin to define the needle entry point. As a result on the label you can see the length of the needle, the X angle, which is the angle inside the axial. Can plane as well as the angle which is the angle in the direction. If you randomly scroll to some other images in 3D segments. You can always click the switch to the in Plainview needle, orients it view icon to jump back to the plane where the entire needle path is displayed, whereas in 2D segments you use the same icon to jump to the plane where the entry point is located. Now that we have to find the needle path in the previous steps, we can go to the next step, select the progress needle workflow step on the updated workflow header you will find the mind needle laser icon. It can only be activated when a needle path is selected which is reachable via my needle laser and the weight of the patient has been entered and confirmed at the beginning of the examination. Otherwise, a message in the workflow header will indicate the current status. For example, no needle. Path defined go to previous step for planning or my needle laser cannot visualize the defined path. Proceed without assistance or replan the path. Click the mine needle laser icon. The system displays a move request. Press and hold the move key until the table stops. When the table stops and has reached the mind needle laser operating position for the selected needle path. 2 fan beam lasers are switched on at the same time projecting the needle entry point and the planned trajectory of the needle path on the skin of the patient. Which pair of laser projectors are used depends on the geometry of the planned needle path. In the examination room, we can now position the needle with the help of the laser guidance system. Normally you should do the following under sterile conditions, but we will just stick the needle into the intervention phantom along the path guided by the lasers and check the images of the recent scans for orientation. With the tip of the needle point to the skin of the patient here of the Phantom directly at the laser beam intersection, align the proximal ends of the instrument so that it is centered at the laser beam intersection. A small piece of paper may help to align the needle ends with a laser beam pierced the needle into the skin of the patient. Here of the Phantom at the marked entry point. As we are now in the examination room, let's show you how to perform the control scan using the iPad above the image segment to the right side of the dose information area there is an icon representing the currently selected scan mode. With this button you can switch from their regular mind needle guide screen so the parameter screen on the tablet which gives the user in room control for the next CT control scan. Here you have scan mode selection scan parameters to program with gantry. And range position displayed. It basically provides a subset of the examination UI for in room control. On the system presented the I sequence I spiral and DIFLUORO scan modes are available. Tap on each scan mode. It's a switch between the three intervention scan modes. When switching between the different scan modes, the center of the scan ranges will be kept at the same position, but the scan coverage will be adapted according to the selected mode and slice parameter. You can of course repeat and I spiral scan for the control scan, but to achieve a better dose efficiency. You can use the I sequence scan mode in the slice parameter you can select the desired slice thickness and image number combinations under half or full detector size. Use full detector size to have a bigger coverage. Use half detector size to save more dose. In this demo we will select 13 * 3 millimeter under acquisition. 128 * 0.6 millimeters. You can also change some scan parameters directly on the iPad. Such as mass, KV, slice, thickness in the area above the image segment on the top, a gram. You can also change, for example the fields of view of the scan range. Tap the button above the scan modes. You can switch back to the regular. My needle guide tablet UI. Since the scan mode has been changed to, I sequence, the scan position needs to be defined. Usually a control scan is needed to check the distance from the needle tip to the target lesion. Zero the center of the eye sequence scan should be positioned at the target lesion. To do so, select the center 2D Axial segment, scroll to the target lesion position. Tap the move to selected axial slice position icon under progress needle step. Tab go to load the scan mode. Now you can press and hold the move button on the joystick until the table stops. To start the sequence can you can go back to the control room and press the start button. As an alternative, the scan can be started also from inside the examination room with the X ray foot switch if available. For each control scan both the thick slice images in the top row and the thin slice images in the MERS are updated and show the recent position of the needle. Scroll through the images to check the needle position. The next step is to adjust the needle. Use the joystick to move the table out of the gantry so that you can operate the needle at a comfortable position. Check the image on the in room monitor. Adjust the angle of the needle according to the image display if needed, and then push the needle forward. It is also possible to check the needle position with the mind needle laser again at any time. Press the move button on the AI joystick to move the table back to the last scan position. The mind needle laser icon can also be activated from the iPad. Repeat the control scan. And adjust needle steps until the needle tip reaches the target lesion. By tapping the finalized icon on the iPad, you finished the mind needle guide workflow. Thank you for watching the mind needle guide 3D workflow video.
