Many motion artifact

Ultrasound is the modality of choice to assess the fetal heart, but even with 3-D ultrasound, the rapid beating of the fetal heart can result in motion artifact
Studies have shown that false alarms stemming from motion artifact
, as well as the inability of conventional oximeters to provide physiological data during emergent events, have led to the misnomer that pulse oximeters are unreliable.
Used with the recently released BIS Pediatric Sensor or BIS Sensor XP, the new BIS XP monitoring systems offer increased resistance to electrocautery artifact, enhanced performance in deep anesthetic states, and improved robustness to interference from noise sources, such as high-frequency motion artifact
which occurs in the operating room and intensive care unit.
By intelligently reducing motion artifact
in CT images, SnapShot Freeze improves visualization, which is important for coronary artery interpretability.
Moreover, imec/Holst Centre developed a motion artifact
handling approach based on band-pass and adaptive filtering.
In this situation, a small High Motion Artifact
(HMA) symbol is displayed next to the numeric NIBP values on the Propaq Encore monitor screen.
CardioNet expects the development project to leverage on its proprietary algorithms and back-end infrastructure, and IMEC's world-class expertise in ultra-low power ECG readout ASIC (application specific integrated circuit) with combined motion artifact
A radiologist and a cardiologist who were blinded to the scanner type evaluated the coronary arteries for motion artifact
using the American Heart Association segment model.
In addition to the motion artifact
caused by this ambulation, cardiac patients can experience low peripheral perfusion on an intermittent or consistent basis.
This is slower than the cath lab, but fast enough that the images are free of motion artifact
The scanner is the size of a mammography unit and uses gentle breast immobilization, allowing for greater patient comfort, as well as reducing motion artifact
and improving image resolution.
