    General Concept The scan protocols for adult are defined according to body regions – Head, Neck, Shoulder, Thorax, Abdomen, Spine, Pelvis, Extremities. The pediatric scan protocols are defined under the folder “Children“. The protocols for special applications are defined under “Special“ (please refer to the Application Guide for Special applications).

  • Page 9: Scan Set Up

    (e. g. 16 x 0.75 mm). Slice width is the true thickness of the reconstructed image. With the SOMATOM Sensation 16, you select the slice collimation together with the slice width desired, the slice width is independent of pitch and algorithm, i. e.
  • Page 10 General During scanning the user normally will get “Real time” reconstructed images in full image quality, if the “fast” slice has been selected. In some cases – this depends also on Scan range, Feed/ Rotation and Reconstruction increment – the Recon icon on the chronicle will be labeled with “RT”.

  • Page 11: Pitch

    E. g.: slice collimation = 16 x 1.5 mm, table moves 24 mm per rotation, then the Pitch Factor = 1 With the SOMATOM Sensation 16, you do not need to select pitch. Once the scan range, scan time, slice colli- mation, and rotation time is defined, the software will adapt the table feed per rotation accordingly.

  • Page 12: Kernel

    General Kernels There are 5 different types of kernels: “H“ stands for Head, “B“ stands for Body, “U“ stands for Ultra High Resolution, “C“ stands for ChildHead, and “S“ stands for Special Application, e. g., Osteo CT. The image sharpness are defined by the numbers – the higher the number, the sharper the image;...

  • Page 13: Effective Mas

    The effective mAs takes into account the influence of pitch on both the image quality and dose: Effective mAs = mAs/Pitch Factor To calculate the dose on the SOMATOM Sensation 16, you simply have to multiply the CTDI per mAs with the...

  • Page 14: Dose Information

    General Dose Information The dose as described by CTDI is displayed on the user interface for the selected scan parameters. The CTDI is measured in the dedicated plastic phantoms – 16 cm diameter for head and 32 cm diameter for body (as defined in IEC 60601 –...
  • Page 15 General The concept of effective dose would allow the com- parison of radiation risk associated with different CT or x-ray exams, i. e. different exams associated with the same effective dose would have the same radiation risk for the patient. It also allows comparing the applied x-ray exposure to the natural background radiation, e.
  • Page 16 Sensation 16 has modified shaped filters which might cause slightly different effective dose numbers (differ- ence not expected to be more than 5%). An update of WinDose for the SOMATOM Sensation 16 is currently developed. * The Calculation of Dose from External Photon Exposures Using Reference Human Phantoms and Monte Carlo Methods.

  • Page 17: Care Dose

    General CARE Dose CARE Dose is a clinical application package that pro- vides real-time tube current modulation for Spiral and Sequential Scanning. CARE Dose reduces patient dose significantly, espe- cially in the regions of shoulder and pelvis. It decreases tube load, which extends the capacity for volume scan- ning with thinner slices, larger volumes or Multi-phase studies.
  • Page 18 General Fig. 5: Principle of CARE Dose tube current adaptation. • CARE Dose is pre-selected by default for all standard protocols. It can be switched on/off in the scan card. • The application of CARE Dose does not require any changes in the scan parameters.

  • Page 19: Workflow

    General Workflow Auto Load in 3D and Postprocessing Presets If there are examinations, where you always do some 3D evaluation after the scanning, you can activate on the Examination Card/Auto Tasking for this recon job the Auto load in 3D. Choose from the pull down menu the Postprocessing type.

  • Page 20: Contrast Medium Iv Injection

    General Some of the Scan protocols, mainly for Angio exami- nations, are already delivered with Auto load in 3D. If you do not like, please deselect the Auto load in 3D and save your scan protocol. Some of the Scan protocols are delivered with links to a Postprocessing protocol.

  • Page 21: How To Create Your Own Scan Protocols

    – Do not mix head and body scan protocols: e. g. do not save a head mode in the abdomen directory. – System/Run offers the tool “Restore Default Scan Protocols“ which allows one to remove user specific scan protocols and to restore the Siemens default settings.
  • Page 22 General – System/Edit offers save/delete Scan Protocols. – System/Run also offers the tool “List Scan Protocols“ which generates an HTML table of all available scan protocols. This list can be printed or saved on Floppy (“File/Save As…“).

    Children Overview This folder contains 20 organ specific pediatric proto- cols with 2 to 5 age or weight dependant subgroups. For your convenience, the protocols are numbered according to the body regions, i. e. from head to extre- mities. The scan protocols for Head and Neck regions are defined according to age, and the scan protocols for the other body regions are defined according to body weight.

    Children Hints in General 1.Topograms: 256 mm lateral topograms are defined for the head modes, and 512 mm AP topograms are defined for the body modes. Please keep in mind that the children’s size can be dramatically different. You should press the “Hold Measurement“ button when- ever the range shown on the real time growing topo- gram is long enough, in order to avoid unnecessary radiation.
  • Page 27 Children The proper personnel and equipment must also be readily available at your disposal in the event of a problem. 6.Oral and rectal contrast administration: Depending on the reason for the exam/status of the patient, oral contrast may or may not be given to these patients. In general, oral contrast is recommended to opacify the intestinal tract, as unopacified bowel can have the appearance of abdominal fluid or mass effect.Oral,...
