NAEOTOM Alpha - Effectuer la transition depuis des scanners Somaris 7 Dual Source Vidéo (Partie 2)

Neatom Alpha Transitioning from Dual source Somaris 7 scanners Part 2 This video is intended to guide you through the new features in Neatom Alpha that might be particularly relevant for experienced users in our dual source scanners based on the Somaris 7 platform. Topics covered in this video include protocol selection, specific scan modes for the Neatom Alpha. Scan and Recon parameters the reconstruction possibilities in the specific alpha scan modes and the specifics of low dose and tin filter in Niatom Alpha protocol selection when deciding on a protocol. The Somaris 10 software still has a patient model dialogue for all routine protocols. It is implemented in a very similar way as in Somaris 7. Only now in Somaris 10, there is now a specific patient model for vascular studies that has been added to the interface after a protocol is selected. The NEA Tom Alpha offers several scan modes which vary depending on the protocol. By double clicking a scan range in the timeline, the scan parameter dialogue opens in the Skin Modes tab. A drop down lists all possible scan modes available for the selected protocol. Specific scan modes For the NEA Tom Alpha, the naming structure of the scan mode provides additional details on its characteristics. Each scan mode is broken down into specific categories. The first category names the purpose of the scan range. It can be, for example, a routine scan, a cardiac scan, or a monitoring scan. The next category of the scan mode depicts the scan type. Namely, spiral flash, dual source sequence, or topogram. The following category of the scan mode is the patient type. This section indicates if this scan mode is classified as an adult or a child mode. Another category is the organ type, which indicates the body region that will be scanned. For example, angio indicates a vessel examination and thorax A thorax examination. This category controls the specific dose and dose curves applied to the body region selected. The spectral category represents the acquisition to be used during the examination and all the Recon possibilities with quantum plus 120KV or 140KV acquisitions are available for full spectral capabilities. With quantum low dose modes AT70KV or 90KV, such As for child protocols or low dose scanning are available. Finally, quantum SN for the TIN filtered protocols at SN100 or SN140KV, the scan option category provides. Additional information. And it is used to indicate any scan options like high resolution. X care or by segment due to the highly improved detector technology. Routine scans on the alpha have a columnation of 0.4 millimeters. In Somara 7 scanners only the high resolution scans were down to the same at 0.4 millimeters, but a comb filter was needed and had to be scanned at higher doses. The Neo Tom Alpha high resolution mode uses no comb filter, has no dose penalty, and has a columnation of 0.2 millimeters in tin filter Quantum or in Quantum Plus scan modes. Let's go into more detail on the Quantum Plus mode. This is the NEA Tom Alpha signature scan mode. This scan mode allows for full spectral capability required to generate the complete spectrum of dual energy. Reconstructions like VNCVCR, iodine maps, mono energetic Kev images and SPP tube voltages of 120 or 140 KV can be used to ensure full spectral capability. Full spectral information is available for every scan at full field of view. In this mode, columnation is at 0.4 millimeters, which corresponds to that of the high resolution scans on Somaris 7. Quantum plus can be combined in scans that use flash X care and even in all cardiac modes with the 66 millisecond temporal resolution. This means there is no longer a choice to be made between flash cardiac. Dual energy or high resolution as was the case in the past. You can get all these options combined now in the same scan using Quantum Plus. The Nea Tom Alpha keeps the TIN filter scan modes and all its benefits used for optimal Lodo scans and keeps high image quality by hardening the beam. The scan modes can be seen with the keyword SN used. Tin filtration is ideal for high contrast protocols without contrast media, reducing beam hardening artifacts and lowering radiation dose due to hardening the beam and removing the lower end Spectra. It is limited for dual energy exams or exams using contrast injections. Mono energetic reconstructions are limited to levels of 60 Kev and above. No VNC, iodine or SPP recons can be used with tin filtration modes. Now that the scan modes have been broken down, we will discuss the relevant scan parameters. In Somaris 10, each protocol can have multiple scan modes available, unlike in Somaris 7 where an individual protocol was needed for each mode. The Neotem alpha also implements the known Care dose 4D and Care KV features. Now Care Kev has the modes of full manual KV and off, and Care Kev optimized for has a setting similar to the slider bar in Somaris 7. These functions behave similarly to Somaris 7 and can be used in the same way as they were previously, with only minor changes that happen in the background due to photon counting technology. For more indepth information with the care features, please refer to the specific care training for the alpha Recon parameters. The options for Recon parameters available in Somaris 7 can also be found on the Neatom alpha. Here you can see the most common Recon parameters in Somaris 10 and their equivalent in the Somaris 7 user interface. Included are Slice, Thickness and Increment. Windowing values kernels and Admire, which in photon counting is now QIR. Note that in photon counting, beam hardening correction is now always on and set to quantum. All the fast technologies known from Somaris 7 are also available in Somaris 10. Notice that for both Recon parameters and fast technologies, additional functionalities are now available which were not previously present in Somaris 7 systems. More advanced dual energy recons can be performed with more technology than was available on Somaris 7. Spectral Recon replaces fast DE results with additional options such as pure Lumen, which are images on which the calcium is subtracted from the vessels after a CTA scan, and T3D, which generates A reconstructed results series. That provides images generated from all photons registered and therefore look like a conventional CT introduced with Somaris 10 is the option of inline results. Inline results uses a landmark detection technology to generate results based on a given organ characteristic. Inline results have the options to produce parallel or radial ranges with the possibility to have the same results in multi energy. Applications like aspect score, Lungcad and Calcium score are also possible. From inline results, the user can select a body region with specific reconstructions that uses this landmark technology for accurate zero click reconstructions. For more information on reconstruction possibilities, please refer to the Reconstruction for Alpha Training. Let's now combine all the information about scanning and reconstructions together. The possible recons depend on the scan mode that was used. Quantum plus mode includes all dual Energy Information and uses 120 or 140 KV. Quantum uses 70 or 90KV and has limited dual energy results. Quantum 10 uses either SN100 or SN140KV. This also has limited dual energy results. A high resolution mode depends on whether you are in a single source mode with only one tube used or dual source mode using both tubes such as a flash or cardiac scan first. We have the quantum plus routine scan mode that has the full dual Energy Information using 120 or 140 KV. Here all spectral images are available for reconstruction. Along with the full capabilities of inline results including all multi energy. Possibilities. This mode is why it is the feature scanned mode of the alpha with the most reconstruction capabilities available. Then we have Quantum plus UHR mode in single source, which again is any scan using just one. Tube. In this mode, spectral results are available in standard reconstruction resolution, such as slice thickness of 0.4 millimeters and kernels up to a 76 sharpness. All high resolution reconstructions of 0.2 millimeters must be a T3D reconstruction. Inline results are also available with the same restrictions for images and standard resolution, and again all high resolution needing to be a T3D. Next. We have the quantum plus UHR dual source mode such as a scan for cardiac or a flash scan. In this mode, due to the amount of information produced, there is no possibility for spectral reconstructions or information and all images will be a T3D. Reconstruction inline results are available for single energy such as parallel radial ranges and applications. Keep in mind that these results will be a T3D reconstruction. There is no. Possibility for D. E Ranges. Or SP. P for dual energy applications. Now we will move on to the Quantum mode. This mode uses 70 or 90KV for all acquisitions. Here you can see that spectral reconstructions are limited to only mono energetic images up to a 130 Kev level and T3D recons. This is due. To a limited spectrum. Range at lower KVP levels. With inline results. The possibilities are. Ranges including parallel and radial along with the applications such as aspect and lung CAD. Notice that no multi energy recons are possible such as an SPP for dual energy applications with the. Quantum UHR scan mode in single source. The spectral reconstructions are limited to standard resolutions to 0.4 millimeters and only mono energetic levels up to 130 Kev. And all high resolution reconstructions at 0.2 millimeters still needs to be a T3D reconstruction. No other spectral results are capable in this mode. Single source inline results are again limited to just radial and parallel ranges and applications. This again follows the standard resolution rules. In dual source UHR mode, no spectral results are possible and all images will be a T3D reconstruction. Inline results are again limited to parallel radial ranges and applications, but only as a T3D reconstruction. Let's look at the possibilities in the Quantum TIN mode. This mode uses TIN 100 or TIN 140KV for all acquisitions. Again, you can see that spectral reconstructions are limited to mono energetic images of 60 Kev and above and also T3D recons. This is due to the hardened spectrum that happens when the TIN filter is applied. With inline. Results the possibilities. Are ranges including parallel and radial along with the applications such as aspect and lung CAD? Notice that no multi energy recons are possible such as an SPP for dual energy applications with the. Quantum tin Uhr scan mode in single source. The spectral reconstructions are limited to standard resolutions to 0.4 millimeters and only mono energetic levels 60 Kev and above. And all high resolution reconstructions at 0.2 millimeters still needs to be a T3D reconstruction. No other spectral results are capable in this mode. Single source inline results are again limited to just radial and parallel ranges and applications. This again follows the standard resolution rules. In dual source UHR mode, no. Spectral results. Are possible and all images will be a T3D reconstruction. Inline results are again limited to parallel radial ranges and applications. But only as a T3D reconstruction. You might have realized that the NEA Tom alpha offers very few scan modes below 120 KV. However, you as users of other non photon counting Siemens Health and EARS CT scanners routinely use low KV settings. This apparent discrepancy can be explained by accounting for the unique properties of the photon counting detectors to illustrate this point. Let's use the example of a CTA exam to explain how counting and non counting scanners reach the same clinical goals. When you tell the scanner to do a vascular scan, both the force and alpha will understand that you want a high contrast to noise ratio CNR to make the iodine bright. Both scanners also understand that to do this they need to get images with low KV energy levels. However, how they attain this lower Kev will be different. The force will drop the KV in the scan to reduce the average Kev of the spectrum. Due to its detector technology, using the lowest KV to maintain the CNR for vascular was needed. However, the effective mas needed to be raised to quite high levels to maintain the dose efficiency at these noise levels. On the other hand, the Nea Tom alpha, using photon counting detectors that capture the entire segregated spectrum, will adjust the reconstructions to be a high CNR mono energetic level of 55 Kev. To maintain the desired CNR at A55K EV level, the effective mas can now be adjusted to a much lower dose. This lower dose value is equivalent to that of the force. So while the force had to drop the KV and raise the MAS to get a good CNR, the alpha will adjust the output reconstructions and use the lowest MAS AT120KV to achieve the desired CNR. To summarize this, the alpha scanner and its new detectors still have the benefits of low KV scanning at the same dose values as before, but now in addition full dual Energy Information is available for interpretation. Thank you for your participation and attention in this training.
