    General Concept The scan protocols for adult are defined according to body regions – Head, Neck, Shoulder, Thorax, Abdomen, Pelvis, Spine, 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. 6 x 1.0 mm). Slice width is the true thickness of the reconstructed image. With the SOMATOM Emotion 6, 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 If Metrorecon is not selected you will get routinely “Real Time” reconstructed images in full image quality. The Recon icon on the chronicle will be labeled with “RT”. After the scan the Real Time displayed image series has to be reconstructed. The following tables show you the possibilities of image reconstruction in spiral and sequential scanning.

  • Page 11: Pitch

    E. g.: slice collimation = 6 x 1.0 mm, table moves 6 mm per rotation, then the Pitch Factor = 1 With the SOMATOM Emotion 6, you do not need to select pitch. Once the scan range, scan time, slice collimation, and rotation time is defined, the software will adapt the table feed per rotation accordingly.

  • Page 12: Kernels

    General Kernels There are 5 different types of kernels: “H“ stands for Head, “B“ stands for Body, “U“ stands for High Reso- lution, “C“ stands for ChildHead, and “S“ stands for Special Application, e. g., Osteo CT. The image sharpness is defined by the numbers – the higher the number, the sharper the image;...
  • Page 13 General Reconstruction with PFO filter. Reconstruction without PFO filter. ASA: The Advanced Smoothing Algorithm (ASA) filter reduces noise in soft tissue while edges with high con- trast are preserved. LCE: The Low-contrast enhancement (LCE) filter enhances low-contrast detectability. It reduces the image noise.

  • Page 14: 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 Emotion 6, you simply have to multiply the CTDI per mAs with...

  • Page 15: Dose Information

    General Dose Information CTDI and CTDI The average dose in the scan plane is best described by the CTDI 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 60601-2 -44).
  • Page 16 General The CTDI value does not provide the entire information of the radiation risk associated with CT examination. For this purpose, the concept of the “Effective Dose“ was introduced by ICRP (International Commission on Radiation Protection). The effective dose is expressed as a weighted sum of the dose applied not only to the organs in the scanned range, but also to the rest of the body.

  • 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 19: Workflow

    General Workflow Auto Load in 3D and Postprocessing Presets You can activate the “Auto load in 3D” function on the Examination Card/Auto Tasking and link it to a recon job. For example, the 2 recon job with thinner slice width in some of the examination protocols. If the post- processing type is chosen from the pull down menu, the reconstructed images will be loaded automatically into the 3D Card on the Navigator with the correspond-...

  • Page 20: Contrast Medium Iv Injection

    General Some of the Scan protocols, primarily for Angio exami- nations, are already preset in the protocol with Auto load in 3D. If you prefer not to use this preset, please de- select the Auto load in 3D and save your scan protocol. Some of the Scan protocols are preset in the protocol with links to a postprocessing protocol.

  • Page 21: How To Create Your Own Scan Protocols

    General How to Create your own Scan Protocols User-specific scan protocols can be saved with the following basic procedure: • Register a test patient, patient position must be Head First – Supine • Select a scan protocol. • Set the table position to 0 (either at the gantry panel, or on the topogram routine card).
  • Page 22 – System/Run offers the tool “Restore Default Scan Protocols“ which allows you to remove user specific scan protocols and to restore the Siemens default settings. – System/Edit offers save/delete Scan Protocols.

    Children Overview This folder contains 24 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“...
  • Page 27 Children The proper personnel and equipment must also be readily available 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.
  • Page 28 Children Note: these injector guidelines are based on an antecubital injection site. These guidelines may need to be adjusted if the site is more peripheral. Needle Size (gauge) Flow Rate (ml/sec.) 2.0 – 3.0 3.0 – 5.0 Central lines and ports may need to be hand injected or power injected at a very low flow rate (1 ml/sec.).

  • Page 29: Head Kernels

    Children Head kernels: • For head scans of small children, the kernels C20s, C30s (e. g. for soft tissue studies) and C60s (e. g. for sinuses) should be chosen instead of the ”adult” head kernels H20s, H30s and H60s. • For soft tissue head studies, the standard kernel is H40s;...

  • Page 30: Body Kernels

    Children Body kernels: • As standard kernels for body tissue studies B30s or B40s are recommended; softer images are obtained with B20s or B10s (extremely soft). The kernels B31s or B41s have about the same visual sharpness as B30s, respectively, B40s, the image appearance, however, is more agreeable due to a ”fine-grained”...
  • Page 31 Children The special kernels are mostly used for ”physical” measurements with phantoms, e. g. for adjustment procedures (S80s), for constancy and acceptance tests (S80s, U90s), or for specification purposes (U90s). For special patient protocols, S80s and U90s are chosen, e. g. for osteo (S80s) and for high resolution bone studies (U90s).
