This online training course provides on-demand training for the Brilliance iCT (including Brilliance iCT TVI and Brilliance iCT SP) version 3.2, Ingenuity CT (including Ingenuity Core and Ingenuity Core128) version 3.5, and the Brilliance 64-channel version 3.5 software in a convenient, iDose and O-MAR increase CT image quality, reduce radiation Southtowns Radiology is pleased to offer Phillips CT technology with iDose and O-MAR to improve image quality while reducing radiation dosage for scans. Artifacts from large metal objects such as orthopedic implants can be problematic in imaging. The aim of this study is to evaluate the effect of iDose(4) iterative reconstruction algorithm on radiation dose and imaging quality at chest-abdomen-pelvis (CAP) CT examinations.

Idose ct

A low radiation dose CT protocol without IV contrast is used in patients with renal stone disease who may need repeated CT examinations for follow up of treatment or surveillance. In this exam, the CTDIvol was 2 mGy, and axial images are reconstructed with both iDose 4 (4-mm [A, B]) and IMR (1-mm [C, D]). For routine abdominal CT studies in which the dose is reduced by 30%–40% (relative to earlier FBP protocols), a moderate level of iteration such as 30%–50% ASIR, SAFIRE strength 3 (S3), or iDose level 3–4 is considered optimal for reducing noise without affecting image quality The iDose 4 reconstruction algorithm first analyzes the projection data, identifying and correcting the noisiest CT measurements (poor signal-to-noise ratio or very low photon counts). A model including the photon statistics is applied to each projection for the detection of very noisy measurements. CT scans using abdomen protocol were taken with various tube currents and tube voltage and keeping collimation and pitch unchanged for all scans. All collected data were reconstructed with different levels of iDose(4) (Level 2, 4, 6) and traditional filtered back projection.

We cannot simply add up "each x-ray." In order to measure dose in CT, the CT Dose Index (CTDI) was invented. A low radiation dose CT protocol without IV contrast is used in patients with renal stone disease who may need repeated CT examinations for follow up of treatment or surveillance. In this exam, the CTDIvol was 2 mGy, and axial images are reconstructed with both iDose 4 (4-mm [A, B]) and IMR (1-mm [C, D]). For routine abdominal CT studies in which the dose is reduced by 30%–40% (relative to earlier FBP protocols), a moderate level of iteration such as 30%–50% ASIR, SAFIRE strength 3 (S3), or iDose level 3–4 is considered optimal for reducing noise without affecting image quality The iDose 4 reconstruction algorithm first analyzes the projection data, identifying and correcting the noisiest CT measurements (poor signal-to-noise ratio or very low photon counts).

Philips will display the iDose 4 iterative reconstruction technique in its booths, #7159 and 7721, at RSNA 2011. The number of CT examinations giving a relatively high patient exposure is increasing. It is therefore important to optimize the imaging conditions at these investigations. Many steps have been taken to reduce the radiation doses in CT examinations.

I Cadaver Test: Influence of iDose Reconstruction on CT Attenuation and Noise Comparison of the pooled noise (across all radiation doses) between the FBP algorithm and the different iDose strengths/levels demonstrated that iDose images had lower overall tissue noise (SD brain stem ) relative to FBP, and the noise progressively reduced with increasing strengths/levels of iDose ( Fig 3 A ).

2012-06-01 2011-07-01 iDose⁴ is an innovative solution that helps you personalize image quality based on your patients’ needs at low dose. When used in combination with the advanced technologies of the iCT, Ingenuity, and Brilliance scanner families, this provides a unique approach to managing important factors in patient care – low energy, low dose, and low injected contrast imaging. feasibility of iDose in CTP imaging and assessed its impact on IQ and radiation dose in low-dose CT acquisition. The authors considered the time point of peak enhancement in normal myocardium for Aim: The purpose of this study was to investigate the visualization of fine biliary ducts with knowledge-based iterative model reconstruction (IMR) in low-dose drip infusion computed tomography (CT) cholangiography (DIC-CT) as compared with filtered back projection (FBP) and hybrid iterative reconstruction (iDose 4). Methods: A total of 38 patients underwent DIC-CT for living donor liver 2016-09-09 2016-01-01 2017-02-15 Coronary CT images of the mid left circumflex artery of an 81-year-old man after coronary stenting with three different reconstruction algorithms (A, FBP; B, iDose 4; C, IMR). Although FBP and iDose 4 in combination with sharper kernels can visualize the stent lumen, the image reconstructed with IMR allows for better visualization of stent lumen by reduction of image noise and blooming artifact. 2016-11-01 Raw CT data of the study subjects were reconstructed using both standard FBP and hybrid IR (iDose; Philips Healthcare, Best, the Netherlands).
