Panorama 0.23T™

www.medical.philips.com/main/products/mri/products/panoramafamily/panorama0.23t_rt/features/

From Philips Medical Systems;
the Panorama 0.23 T, providing a new design optimized for patient comfort, faster reconstruction time than before (300 images/second) and new gradient specifications. Philips' Panorama 0.23 T I/T supports MR-guided interventions, resulting in minimally invasive procedures, more targeted surgery, reduced recovery time and shorter hospital stays. Optional OptoGuide functionality enables real-time needle tracking. Philips' Panorama 0.23 TPanorama 0.2 R/T is the first and only open MRI system to enable radiation therapy planning using MR data sets. The Panorama also features the new and consistent Philips User Interface, an essential element of the Vequion clinical IT family of products and services.

Phase Encoded Motion Artifact

Mass Spectrometry - Chemistry - Bioinformatics - Liver Imaging - Corporations - Supplies

Quick Overview
Please note that there are different common names for this artifact.

Artifact Information

NAME

Phase encoded motion, motion, phase effect

DESCRIPTION

Blurring and ghosting

REASON

Movement of the imaged object

HELP

Compensation techniques, more averages, anti spasmodic, presaturation

This artifact is caused by movements of the patient or organic processes taking place in the body of the patient. The artifact appears as bright noise, repeating densities or ghosting in the phase encoding direction.

Image Guidance

There are different solutions for reduction of phase encoded motion artifacts.
Cardiac and respiratory gating, breath holding, sedation of the patient, presaturation pulses for flow artifacts (e.g. arterial pulsation, breathing), fast imaging sequences, etc.

See also Motion Artifact, Ghosting Artifact, Motion Compensation Pulse Sequences and Artifact Reduction - Motion.
