Scan and Reconstruction 21 Scan Modes Sequential Scanning This is an incremental, slice-by-slice imaging mode in which there is no table mo vement during data acquisi- tion. A minimum interscan delay in betw een each acquisition is required to move the table to the next slice position.
22 Scan and Reconstruction Quick Scan The data is usually ac quir ed during a full 360° rotation – this is a Fu ll scan. Da ta acquisition no t using a f ull 360° ro tation is called a “Quick scan”. Quick scans ar e employ ed to reduce mo tion artifacts and improv e the temporal r esolution.

32 Scan and Reconstruction Head K ernels For soft tissue head studies, the st andard k ernel 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, respec tively .
Scan and Reconstruction 33 Body K ernels As standard kernels f or body tissue studies B30s or B40s are recommended; softer images are obtained with B20s or B10s (extremely soft).
34 Scan and Reconstruction Extended F oV SOMA TOM Emo tion 16/6-slice configuration of fers the extended field of view . The range can be individually adapt ed by the user fr om 50 cm up to 70 cm. T o u se this feature yo u have t o select the extended FoV checkbo x on the Recon subtask card.
Scan and Reconstruction 35 Auto- FoV After scanning a topog ram the available ranges ar e dis- play ed in the topo segment. They can be auto matically adapte d according to the patient cont ours. When mov- ing the scan range ov er the topogram and pr ess the " ctrl " key simultaneous, the adaptation will be d one automatically .
36 Scan and Reconstruction Hints • When positioning the arms along the body , the Auto- FoV will also cover the arms. • When scanning two extrem it ies at the same time, the Auto-FoV will also cov er both extremities.
Scan and Reconstruction 37 Neur o Modes In addition to t he standard collimations, the SOMA- TOM Emo tion 16-slice configuration provides a special mode which is optimized f or Neuro applications. Ex cel- lent low contrast and de tail resolution are ac hieved.
38 Scan and Reconstruction Aut omatic Bone Corr ection The head pro tocols pr ovide significant impr ovements regar ding image quality f or heads. An automatic bone correc tion algorithm has been included in the standard image reconstruc tion.
Scan and Reconstruction 39 Positioning In order to op timize image quality versus radiation dose, scans in body regions “Head” and “AngioHead” are pr ovided within a maximum scan field of 300 mm with respec t to the iso-cent er . No r econ job with a field of view exceeding those limits will be possible.
40 Scan and Reconstruction Image F ilters If you use k ernels, the images are r econstruct ed again with the select ed k ernel value. If you use image filters, the images are no t reconstruct ed again and the result is much quicker .
Scan and Reconstruction 41 "HCE": The High-contrast enhancement (HCE) filt e r enhances high-contrast detectability . It increases the image sharpness, similar to reconstruction with a sharper k ernel.
42 Dose Information CTDI W and CTDI Vol The av erage dose in the scan plane is best described by the CTDI W f or the selected scan parame ters. The CTDI W is measured in dedicated plastic phantoms – 16 cm diamet er for head and 32 cm diamet er fo r body (as defined in IEC 60601 – 2 – 44).
Dose Information 43 Note : Previously t he dose display on the user interface was labeled “CTDI W “. This displa yed CTDI W was also cor- rec ted for the pitc h and was therefor e identical to the current CTDI Vol . The CT DI w value does no t pro vide the entire inf orma- tion of the radiation risk associated wit h CT examina- tion.
44 Dose Information Impac tDose For most of the scan pro tocols, the effec tive dose num- bers for standard male* and female* ar e calculated, and listed the r esult in the description of each scan pro- toc ol . The calculation was performed using the commercially availa ble prog ram "Impac tDose" (W ellhoef er Dosime- tr y).
Dose Information 45 Ef f ectiv e mAs In sequential scanning, the dose ( D seq ) applied to the patient is the pr oduct of the tube curr ent-time (mAs) and the CTDI w per mAs: In spiral scanning, howe ver , the applied dose (D spiral ) is influenced by the conventional mAs (mA x Ro t Time) and additionally by the pitch factor .
46 Dose Information For spiral scan pro tocols, t he indicated mAs is the effectiv e mAs per image. The correlation be tween tube current and effec tive mAs of spiral scans on a Multi- slice CT scanne.
Dose Information 47 C ARE Dose 4D C ARE Dose 4D is an aut omated exposur e control, which ensures constant diagno stic image quality o ver all body regions at the lowest pos sible dose.
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.
Dose Information 49 How does CARE Dose 4D work? C ARE Dose 4D combines two types of tube current modulatio n: 1) Axial tube current modulation: Based on a single T opogram (a.
50 Dose Information 2) Angular tube current modulation: Based on the abov e described axial ef f. mAs profiles, the tube current is modulat ed during each tube ro ta- tion.
Dose Information 51 Scan with constant mA Reduced dose level Real-time angular slice position x-ray dose based on topogram dose modulation.
52 Dose Information Principle of automatic tube current adaptation b y C ARE Dose 4D for a spiral scan fr om shoulder to pelvis (very high table feed fo r demonstration): High tube current and strong modulation in shoulder and pelvis, lower tube current and low modulation in abdomen and thorax.
Dose Information 53 Special Modes of C ARE Dose 4D For certain examination pr otocols CARE Dose 4D uses modified tube current modulation, to mee t specific conditions, for ex ample: • for Adult He ad pro tocols the tube current is adap ted to the variation alo ng the pa tient ’s long axis and not to the angular attenuation profile.
54 Dose Information Scanning with C ARE Dose 4D If the settings of Image Quality Ref erence mAs ar e cor- rec tly predefined*, no fur ther adjustment of the tube current is r equir ed to perform a scan. CA RE Dose 4D automatically adap ts the tube current to different patient sizes and anat omic shapes, but it widely ignores me tal implants.
Dose Information 55 Outside the topogram range, C ARE Dose 4D will con- tinue the scan with the last a vailable topogram inf or- mation. Without a topogram, CARE Dose 4D cannot be switched on. Repositioning of the patient on the table and exces sive motion of the patient must be avoided between the to pogram and the scan.
56 Dose Information After the topogram has been scanned, the (eff.) mAs value in the Routine tab card displa ys the mean (eff.) mAs estimated b y C ARE Dose 4D based on the t opo- gram*. After the scan has been per formed this va lue is updated to the mean (eff.
Dose Information 57 The Quality ref erence mAs value is displayed on the Scan tab card. This defines th e ov erall image quality of the scan prot ocol currently being used. This value can be adapted f or each pr otocol accor ding to the user ’s individual requir ements of image quality .
58 Dose Information Adjusting the Image Noise The correlation be tween attenuation and tube curr ent is defined by the analytical func tion described above. This function ma y be adjusted t o adapt th e image qual- ity (image noise) accordi ng to t he diagnostic r equir e- ments and the individual pref erence of t he radiologist.
Dose Information 59 If you change the quality r ef. mAs, a pop-up window is displayed. • T o change the configurat ion of C ARE Dose 4D, please open the Examination Configuration dialog box under Op tions > Configuration . In the window that then appears, please double-click the Examina- tion icon to displa y the configuration window .
60 Dose Information – i f the automatic dose increa se for obese patients (or patient sections) has to be mor e moderate than the prese t (ch oose obese: w eak increase ), resulting in more image noise and a lower dose for those images.
Dose Information 61 Activating and Deac tivating C ARE Dose 4D ma y be activat ed or deactiva ted f or the current scan in the Scan tab card. If CARE Dose 4D is activated as default, the Imag e Quality Reference mAs value is se t to the default value of the pro tocol.
62 Dose Information If you ar e unsure about the co rrect Image Quality Ref- erence mAs v alue, f ollow this sim ple pr ocedure: • Enter the (eff.) mAs value used for that type of pro- tocol without CA RE Dose 4D. • There is a simple way of ascertaining what ef f.
Dose Information 63 Additional Import ant Information For ideal dose application it is very impor tant to posi- tion the patient in the isocente r of the gantr y .

122 Contrast Medium Contrast Medium The Basics The administration of intrav enous (IV) contrast mate- rial during spiral scanning impr ov es the tissue and lesion charact erization, as well as the opacity of ves- sels.
Contrast Medium 123 The dynamics of the contrast enhancement is det er- mined by: • Patient cardiac output •I n j e c t i o n r a t e • T otal volu me of contrast medium inje cte d • Concentration of the contrast medium • T ype of inject ion – un i-phasic or bi-phasic • Patient pathology Aortic time-enhancement cur v es after i.
124 Contrast Medium Injection rate: 2 ml/s, 120 ml, 300 mg I/ml Injection rat e: 4 ml/s, 120 ml, 300 mg I/ml T o tal volume of contrast medium injected: 80 ml, 4 ml/s, 30 0 mg I/ml T o tal volume of c.
Contrast Medium 125 IV Injection* The administration of a contrast medium depends on the indication and on the delay times t o be used during the examination.
126 Contrast Medium Bolus T racking An automatic Bolus T racking program is av ailable which enables triggering of the spiral scanning a t the optimal phase of the contrast enhancement. Additional Important Information 1. This mode can be used in combination with any spi- ral scanning prot ocol.
Contrast Medium 127 – Move the monit oring scan line toward the optimal position and release the mouse button, it will be snapped automatically . (T rick: if you move the mon- itoring scan line away from the op timal position the snapping mechanism will be inactive).
128 Contrast Medium T est Bolus using C ARE Bolus Y o u can use the CARE Bolus option as a T est Bolus . Method 1. Inser t a Bolus T racking via the context menu prior to the spiral. 2. Inser t contrast from the context menu. Note : By inser ting contrast you are int errupting the Auto rang e function pre venting an automa tic star t of the spiral.
Contrast Medium 129 T est Bolus This is a low dose sequential pro tocol without table feed used t o calculate t he star t dela y of a spiral scan to ensure optimal enhancement after the contrast medium injec tion. The syngo Dynamic Evaluation function may be used t o generate the time density cur ve.
130 Contrast Medium 6. Load the images into the DynEva task card and det ermine the time to peak enhancement. Alterna- tively , on t he image segment, click select series with the right mouse button and position an ROI on the first image. This ROI will appear on all images in the test bolus series.
Contrast Medium 131 Wor k fl ow T o star t a contrast enhanced examination in coupled mode: • Select the Scan subtask card. • Selec t under the menu field Scan Start either the entr y Injector cou.
132 Contrast Medium After the inject or is armed the scan and the injector can be star ted b y pressing either the Star t button/ Footswitc h at the scanner , or the St a r t button at t he inject or panel outside of the scan room or dir ectly at the inject or inside the scan room.
Contrast Medium 133 Additional Important Information •I f Coupled Mode is select ed the CT checks if ther e is an injector a vailable. The scan mode cannot be loaded if a connec tion can- not be established or if the injector does no t accept coupling (The injector will no t accept coupling while injecting).
134 Contrast Medium The injector r eports a tec hnical problem: The connection be tween scanner and injec tor is int er- rupt ed, or the injection was stopped due t o technical problems. In this ca se the scan continues and an erro r message pops up. The user can decide if he wants t o stop the scan or if he would lik e to continue.
