Dual Energy Monoenergetic in Radiation Oncology with FAST DE Results

Dual Energy Monoenergetic in Radiation Oncology withFAST DE REsults step by step

Monoenergetic Dual Energy in Radiation Oncology with FAST DE Results Computed Tomography FAST DE Results is a quick way to reconstruct Dual Energy images directly at the scanning console/Acquisition Workplace. Many different keV levels are available for reconstruction depending on the desired outcome. Rho (electron density) and Z (atomic number) series are available as well (depending on software version). Low keVs can be used for better soft tissue delineation (i.e. Head/Neck, Liver/Pancreas, Bladder/Prostate) and higher keVs can be used for increased Metal Artifact Reduction in conjunction with iMAR for certain metals (i.e. titanium, gold, spine implants). 1.

When the reconstruction is complete, open the Patient Browser. The FAST DE series is typically preceded by a "600" number and will be labeled according to the type of reconstruction that was selected, e.g. _Mono40_. The FAST DE series can be sent from the Patient Browser to any established network node or to other Task Cards, such as Viewing or 3D.

Z = effective number because of too many atoms in inside of pixel and it is averaged Rho = give a value of CT image and it's the same calculation of CT to convert into electron density directly. i.e CT value of the Rho is 55HU (1000+Rho)/1000=electron density  electron density is 1.055 Siemens Healthineers Services Page 2 of 3 Job Aid | Monoenergetic Dual Energy in Radiation Oncology with FAST DE Results Effective Date: 8/18/2017 | Quality HOOD05162002645758 Please note that the learning material is for training purposes only!
