  • Page 21: Scan Modes

    Scan and Reconstruction Scan Modes Sequential Scanning This is an incremental, slice-by-slice imaging mode in which there is no table movement during data acquisi- tion. A minimum interscan delay in between each acquisition is required to move the table to the next slice position.
  • Page 22: Quick Scan

    Scan and Reconstruction Quick Scan The data is usually acquired during a full 360° rotation – this is a Full scan. Data acquisition not using a full 360° rotation is called a “Quick scan”. Quick scans are employed to reduce motion artifacts and improve the temporal resolution.
  • Page 23: Ufc Detector

    Scan and Reconstruction UFC detector Siemens’ proprietary, high-speed Ultra Fast Ceramic (UFC) detector enables a virtually simultaneous read- out of two projections for each detector element.

  • Page 32: Head Kernels

    Scan and Reconstruction Head Kernels For soft tissue head studies, the standard kernel is H40s; softer images are obtained with H30s or H20s, H10s, sharper images with H50s. The kernels H21s, H31s, H41s yield the same visual sharpness as H20s, H30s or H40s, respectively.
  • Page 33: Body Kernels

    Scan and Reconstruction 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 acceptable due to a "fine-grained"...
  • Page 34: Extended Fov

    Scan and Reconstruction Extended FoV SOMATOM Emotion 16/6-slice configuration offers the extended field of view. The range can be individually adapted by the user from 50 cm up to 70 cm. To use this feature you have to select the extended FoV checkbox on the Recon subtask card.
  • Page 35: Auto-fov

    Scan and Reconstruction Auto-FoV After scanning a topogram the available ranges are dis- played in the topo segment. They can be automatically adapted according to the patient contours. When mov- ing the scan range over the topogram and press the "ctrl"...
  • Page 36 Scan and Reconstruction Hints • When positioning the arms along the body, the Auto- FoV will also cover the arms. • When scanning two extremities at the same time, the Auto-FoV will also cover both extremities.
  • Page 37: Neuro Modes

    Scan and Reconstruction Neuro Modes In addition to the standard collimations, the SOMA- TOM Emotion 16-slice configuration provides a special mode which is optimized for Neuro applications. Excel- lent low contrast and detail resolution are achieved. For spiral scans 4 x 0.6 acquisition mode is provided in the range of the cerebrum.
  • Page 38: Automatic Bone Correction

    Scan and Reconstruction Automatic Bone Correction The head protocols provide significant improvements regarding image quality for heads. An automatic bone correction algorithm has been included in the standard image reconstruction. Using a new iterative technique, typical artifacts arising from the beam-hardening effect, for example, Hounsfield bar, are minimized without additional post-processing.
  • Page 39: Positioning

    Scan and Reconstruction Positioning In order to optimize image quality versus radiation dose, scans in body regions “Head” and “AngioHead” are provided within a maximum scan field of 300 mm with respect to the iso-center. No recon job with a field of view exceeding those limits will be possible.
  • Page 40: Image Filters

    Scan and Reconstruction Image Filters If you use kernels, the images are reconstructed again with the selected kernel value. If you use image filters, the images are not reconstructed again and the result is much quicker. Three different filters are available: LCE: The Low-contrast enhancement filter enhances low-contrast detectability.
  • Page 41 Scan and Reconstruction "HCE": The High-contrast enhancement (HCE) filter enhances high-contrast detectability. It increases the image sharpness, similar to reconstruction with a sharper kernel. • Increases sharpness • Faster than raw-data reconstruction • Enhances high-contrast detectability • Automatic post-processing Image taken without Image taken with the the HCE filter HCE filter...
  • Page 42: Dose Information

    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 dedicated plastic phantoms – 16 cm diameter for head and 32 cm diameter for body (as defined in IEC 60601 –...
  • Page 43 Dose Information Note: Previously the dose display on the user interface was labeled “CTDI “. This displayed CTDI was also cor- rected for the pitch and was therefore identical to the current CTDI The CTDI value does not provide the entire informa- tion of the radiation risk associated with CT examina- tion.
  • Page 44: Impactdose

    Dose Information ImpactDose For most of the scan protocols, the effective dose num- bers for standard male* and female* are calculated, and listed the result in the description of each scan pro- tocol. The calculation was performed using the commercially available program "ImpactDose"...
  • Page 45: Effective Mas

    CTDIw Pitch Factor To simplify this task, the concept of the “effective“ mAs was introduced with the SOMATOM Multislice scan- ners. The effective mAs takes into account the influence of pitch on both the image quality and dose: Effective mAs =...
  • Page 46 Dose Information For spiral scan protocols, the indicated mAs is the effective mAs per image. The correlation between tube current and effective mAs of spiral scans on a Multi- slice CT scanner is expressed by the following formula: Effective mAs = mA x RotTime Pitch Factor Pitch Factor = Feed per Rotation nrow x Slice collimation...
  • Page 47: Care Dose 4d

    Dose Information CARE Dose 4D CARE Dose 4D is an automated exposure control, which ensures constant diagnostic image quality over all body regions at the lowest possible dose. CARE Dose 4D combines three different adaptation methods to optimize image quality at the lowest dose level: •...
  • Page 48 Dose Information Based on a user defined Image Quality Reference mAs, CARE Dose 4D automatically adapts the (eff.) mAs to the patient size and attenuation changes within the scan region. With the setting of the Image Quality Reference mAs you can adjust image quality (image noise) to the diagnostic requirements and the individual preference of the radiologist.
  • Page 49: How Does Care Dose 4d Work

    Dose Information How does CARE Dose 4D work? CARE Dose 4D combines two types of tube current modulation: 1) Axial tube current modulation: Based on a single Topogram (a.p. or lateral) the atten- uation profile along the patient’s long axis is measured in direction of the projection and estimated for the per- pendicular direction by a sophisticated algorithm.
  • Page 50 Dose Information 2) Angular tube current modulation: Based on the above described axial eff. mAs profiles, the tube current is modulated during each tube rota- tion. Therefore the angular attenuation profile is mea- sured automatically during the scan and the tube cur- rent is modulated accordingly in real time to achieve an optimum distribution of the X-ray intensity for every viewing angle.
  • Page 51 Dose Information Reduced dose level Scan with constant mA Real-time angular based on topogram dose modulation slice position...
  • Page 52 Dose Information Principle of automatic tube current adaptation by CARE Dose 4D for a spiral scan from shoulder to pelvis (very high table feed for demonstration): High tube current and strong modulation in shoulder and pelvis, lower tube current and low modulation in abdomen and thorax.
  • Page 53: Special Modes Of Care Dose 4d

    Dose Information Special Modes of CARE Dose 4D For certain examination protocols CARE Dose 4D uses modified tube current modulation, to meet specific conditions, for example: • for Adult Head protocols the tube current is adapted to the variation along the patient’s long axis and not to the angular attenuation profile.
  • Page 54: Scanning With Care Dose 4d

    CARE Dose 4D. *For Siemens scan protocols of SW version syngo CT 2007E, the settings of CARE Dose 4D are already pre- defined but may be changed to meet the customer’s...
  • Page 55 Dose Information Outside the topogram range, CARE Dose 4D will con- tinue the scan with the last available topogram infor- mation. Without a topogram, CARE Dose 4D cannot be switched on. Repositioning of the patient on the table and excessive motion of the patient must be avoided between the topogram and the scan.
  • Page 56 Dose Information After the topogram has been scanned, the (eff.) mAs value in the Routine tab card displays the mean (eff.) mAs estimated by CARE Dose 4D based on the topo- gram*. After the scan has been performed this value is updated to the mean (eff.) mAs that was applied.
  • Page 57 Dose Information The Quality reference mAs value is displayed on the Scan tab card. This defines the overall image quality of the scan protocol currently being used. This value can be adapted for each protocol according to the user’s individual requirements of image quality. Here you can also view the effective mAs value that the system is going to use for the current scan range.

    Respiratory Gating Temporal Resolution Temporal resolution, also called time resolution, repre- sents the time window of the data that is used for image reconstruction. It is essential for respiratory CT imaging. The higher the temporal resolution, the fewer the motion artifacts. A temporal resolution of a half of the Rotation Time can be achieved.

    Respiratory Gating Curve Editor The respiration curve editor is used to modify the res- piratory signal. This editing tool is available after spiral scan data has been acquired. By using the right mouse menu on the Trigger tabcard you have access to several modification tools for the respiratory Syncs (purple dots above and below the curve), such as Delete, Dis- able, Insert.

    Respiratory Gating Synthetic Trigger/Sync By default, the "Synthetic Trigger" (Respiratory-trig- gered scanning) or "Synthetic Sync" (Respiratory-gated scanning) is activated for all predefined Respiratory scan protocols. It is recommended to always keep it activated for examinations with contrast medium. In case of Respiratory signal loss during the acquisi- tion, this will ensure the continuation of the triggered scans or allows a Respiratory signal to be simulated for retrospective gating.
