1 CT General FC reconstruction filters Reconstruction function comparison table: Aquilion 16-slice system () vs. Aquilion 4-slice system () We have prepared simplified comparison tables of the reconstruction functions for the and the. Use these tables as reference data when changing exam Plans etc. Note that data concerning image noise and MTF characteristics for each reconstruction function for the will be provided separately. [Applicable system software] : V1.30 or later : V1.7 or later
2 <Abdominal functions with BHC processing (in the FC00 range)> FC04 FC04 FC05 FC05 FC01 FC01 FC02 FC02 FC03 FC03 Figure 1 vs. : Comparison table of the abdominal functions with BHC processing Figure 1 shows the relationships between the abdominal functions with BHC processing for the and those for the. The functions near the top provide sharper images, while the functions near the bottom provide smoother images. FC01 to FC05 for the have been optimized so that they provide approximately the same level of image quality as FC01 to FC05, respectively, for the.
3 <Abdominal functions without BHC processing (in the FC10 range)> FC13 FC13 FC14 FC14 FC10 FC10 FC11 FC11 FC12 FC12 Figure 2 vs. : Comparison table of the abdominal functions without BHC processing Figure 2 shows the relationships between the abdominal functions without BHC processing for the and those for the. The functions near the top provide sharper images, while the functions near the bottom provide smoother images. FC10 to FC14 for the have been optimized so that they provide approximately the same level of image quality as FC10 to FC14, respectively, for the. The recommended abdominal function for the is FC10.
4 <Head functions with BHC processing (in the FC20 range and FC67 to FC69)> Aquilio n / 4 FC25 FC25 FC20 FC24 FC67 FC23 FC68 FC69 FC27 FC26 FC21 FC22 FC28 FC20 FC24 FC67 FC23 FC68 FC69 FC27 FC26 FC21 FC22 FC28 Figure 3 vs. : Comparison table of the head functions with BHC processing Figure 3 shows the relationships between the head functions with BHC processing for the and those for the. The functions near the top provide sharper images, while the functions near the bottom provide smoother images. FC20 to 28 and FC67 to 69 for the have been optimized so that they provide approximately the same level of image quality as FC20 to 28 and FC67 to 69, respectively, for the. The recommended head function for the is FC27 or FC69.
5 <Functions for the ear and bones (in the FC30 range)> FC30 FC30 FC31 FC31 Figure 4 vs. : Comparison table of the functions for the ear and bones Figure 4 shows the relationships between the functions for the ear and bones for the and those for the. The functions near the top provide sharper images, while the functions near the bottom provide smoother images. Reconstruction functions FC30 and FC31 for the are also identical to FC30 and FC31, respectively, for the.
6 <Head functions without BHC processing (in the FC40 range)> FC42 FC42 FC43 FC43 FC44 FC44 FC48 FC48 FC46 FC46 FC47 FC47 FC41 FC41 Figure 5 vs. : Comparison table of the head functions without BHC processing Figure 5 shows the relationships between the head functions without BHC processing for the and those for the. The functions near the top provide sharper images, while the functions near the bottom provide smoother images. FC41 to 48 for the have been optimized so that they provide approximately the same level of image quality as FC41 to 48, respectively, for the.
7 <Chest functions (in the FC50 range)> FC52 FC53 FC52 FC53 FC51 FC50 FC50 FC51 Figure 6 vs. : Comparison table of the chest functions Figure 6 shows the relationships between the chest functions for the and those for the. The functions near the top provide sharper images, while the functions near the bottom provide smoother images. Reconstruction functions FC50 and FC52 for the are identical to FC51 and FC53 respectively, for the. The recommended chest functions for the are FC51 for thin slice thicknesses and FC52 for thick slice thicknesses (routine images).
8 <Xe-Study function (FC60)> Aquilio n / 4 FC60 FC60 Figure 7 vs. : Xe-Study function comparison table Figure 7 shows the relationships between the Xe-Study function for the and that for the. FC60 for the has been optimized so that it provides approximately the same level of image quality as FC60 for the.
9 <High-definition functions (in the FC80 range)> FC81 FC81 FC80 FC80 FC82 FC82 FC83 FC83 FC84 FC84 FC85 FC85 Figure 8 vs. : High-definition function comparison table Figure 8 shows the relationships between the high-definition functions for the and those for the. The functions near the top provide sharper images, while the functions near the bottom provide smoother images. Reconstruction functions FC80 to 85 for the are also identical to FC80 to 85, respectively, for the. The resolution is slightly lower for TCOT reconstruction than for MUSCOT reconstruction.
