iDose4 improves image quality through artifact prevention and increased spatial resolution at low dose while O-MAR reduces artifacts caused by large orthopedic implants. Philips Incisive CT education provides quick tips to compliment powerful enhanced clinical workflow and application training videos. The resources on this page will … 2019-09-23 2013-06-13 iDose4™ substantially improves image quality and lesion conspicuity and reduces noise in low-dose chest CT. Compared to RDCT, high iDose4™ levels provide equivalent image quality in LDCT, hence suggesting a potential dose reduction of almost 80%. Contrast-to-noise ratio significantly increased with iDose4 and IMR compared to FBP (p<0.05). Subjective image quality was rated significantly higher at IMR reconstructions in comparison to iDose4 and FBP. Conspicuity of central and segmental PE significantly improved with the use of IMR. In subsegmental arteries, iDose4 was superior to IMR. Together they produce high image quality with reduced artifacts.

filtered back-projection (FBP), iterative reconstruction (iDose4) and IMR, with and without O-MAR. Computed Tomography (CT) numbers, noise levels, Mar 13, 2019 Relative agreement among iDose4 reconstructions was quantified using the Spearman's rank correlation coefficient. For all ROIs besides those following which iDose4-3 and iDose4-5 were used for target reconstruction, of U-HRCT image was lower than that of the C-HRCT image of the same iDose4 Data were reconstructed using FBP and two different IR techniques iDose4™ and IMR (Philips Healthcare) at various iteration levels.

The images were reconstructed using filtered back projection (FBP) and different settings of hybrid (iDose4) and model-based (IMR) iterative reconstruction methods. Results: iDose4 decreased the noise by 15–45% compared with FBP depending on the level of iDose4. The IMR reduced the noise even further, by 60–75% compared to FBP.

Guidelines for selection iDose4 parameters based on the imaging need will be explained. To assess diagnostic quality of sub milli-Sievert (submSv) chest and abdominal CT reconstructed with iterative model reconstruction (IMR) and iDose4. METHOD AND MATERIALS In a prospective clinical study, 20 patients (BMI<30kg/m2, chest, n=10 age range:26-90; abdomen, n=10 age range:30-84) gave written informed consent for the acquisitions of submSv additional images (0.9mSv) on a 256-slice CT @article{osti_1770342, title = {Digital Image Correlation as an Experimental Modal Analysis Capability.}, author = {Witt, Bryan Lee and Rohe, Daniel Peter}, abstractNote = {Digital image correlation (DIC) is an established test technique in several fields including quasi-static displacement measurements.

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. Currently much work is related to iterative image reconstruction methods as alternative to the filtered back projection method.

When used in combination with the advanced CT scan technologies this provides a unique approach to managing important factors in patient care – a new era in low energy, low dose and low injected contrast imaging. The results show that the detection of the solid nodules is robust to imaging parameters, and for GGO detection, reconstruction methods “iDose4-YA” and “STD-YA” achieve better performance. For thin-slice images, higher performance is achieved across different nodule sizes with reconstruction method “iDose4-STD”. For 1-mm thickness images, iDose4-STD and FBP-STD shows a better result in both sensitivity and precision metrics.

Dose reductions of up to 76% have been reported without a loss of image quality [18]. A reconstruction speed of 18 slices per second can be reached using iDose4, which is slightly slower than Designed to seamlessly integrate into your CT department, iDose4 improves image quality* with the look and feel of conventional images. iDose⁴ || Reconstruction in 60 seconds o.
