Philips introducerar en ny CT-plattform som ger lika bra

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 Ct idose brochure 1. You control the dialPhilips CT iDose4 iterative reconstruction technique 2. The results you want Philips iDose4 is an iterative reconstruction technique that gives you control of the dial so you can personalize image quality based on your patients’ needs at low dose. When used in combination with the advanced technologies of Offers 4 cm coverage for excellent image quality and is also available with iDose4. The scanner provides high image quality at low dose with up to 57% improvement in spatial resolution.

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. As for 2-mm thickness images, iDose-YA and FBP-YA gain a better performance.

Objective image noise  Sep 9, 2016 Noise reduction of 55% was achieved with iDose4 and of 85% with IMR compared to FBP. Contrast-to-noise ratio significantly increased with  MATERIALS AND METHODS. We considered chest, abdomen, and pelvis CT examinations before the installation of an iterative reconstruction algorithm ( iDose4)  Sep 27, 2019 Average image noise was significantly lower when re- constructed with MBIR than with iDOSE4 at the same low radiation doses. The two  iDose4 — the latest addition to Philips'.

Images from the standard examination were reconstructed with a hybrid iterative reconstruction method (iDose4), and images from the low-dose examinations were reconstructed with both iDose4 and IMR. Image quality was evaluated subjectively by three observers, according to modified EU image quality criteria, and evaluated objectively based on the noise observed in liver images. iDose4, a hybrid IR technique, filters noise iteratively in both the projection domain and the image domain [17].

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 Thermo Fisher 3d reconstruction software amira 3d Reconstruction Software Amira, supplied by Thermo Fisher, used in various techniques. Bioz Stars score: 99/100, based on 9 PubMed citations. Philips offers advances in CT design and technology to help give you the speed and performance to do more. Enter the realm of multislice CT with ease, or use our most advanced multislice scanners to stay at the forefront of CT imaging. iDose4 Premium Package helps produce high image quality with reduced artifacts: iDose4 improves image quality through artifact prevention and increased spatial resolution at low dose. O-MAR reduces artifacts caused by large orthopedic implants.
