Pediatrics, 1993
To the Editor.— Neonatologists frequently contend with artifacts produced by medical equipment causing unwanted shadows on chest and abdominal radiographs. These artifacts are frequently caused by monitoring equipment and respiratory tubing. We have not yet encountered cases of religious artifacts causing such distorting images.

Journal of Magnetic Resonance Imaging, 2021
During the ongoing COVID‐19 pandemic, an artifact with hyperintense signal was observed on the brain images of a number of patients or research subjects, particularly those with heavy body weight and/or increased respiratory rate. The artifact was primarily seen on 3D or 2D sagittal or coronal T2‐weighted images, although it occasionally also appeared ...

Artifacts and artifact reduction in sonoelastography
2000 IEEE Ultrasonics Symposium. Proceedings. An International Symposium (Cat. No.00CH37121), 2002A technique for reducing vibration artifacts encountered when using pure tone vibration in vibration amplitude sonoelastography is presented. Multi-tone signals were designed to synchronize with the pulse repetition frequency and packet size of the scanner.

Is It Real or Is It an Artifact
Ultrasound Quarterly, 2001Sonographic artifacts are inherent to the modality and occur to some extent in every image. This is despite optimal technique and scanning parameters. Artifacts occur in both gray-scale and color Doppler imaging, and though many are readily recognizable as such, occasionally, an artifact may obscure the diagnosis or even create false pathology.

SSRN Electronic Journal, 2018
The essay discusses the historiographical strategy of "following artifacts" in the history of contemporary economics. Following models as artifacts means (1) to follow the shifts and changes in their form and meaning; (2) to follow the ideas, theories, fictions, and imaginary worlds they provoke; and (3) to investigate the ways in which some of them ...

Abstract This chapter focuses on different types of biological and nonbiological artifacts in MEG and EEG recordings, and discusses methods for their recognition and removal. Examples are given of various physiological artifacts, including eye movements, eyeblinks, saccades, muscle, and cardiac activity.

The thesis that law is an artifact has several implications: that the instantiations of law have authors and are intentionally created, that law has a function, that law is a special type of artifact, i.e. an institutional, abstract, public and social artifact, and that law cannot exist if it is not socially efficacious.

Abrupt narrowing of the male anterior urethra has been increasingly observed during voiding cystourethrography due to extrinsic pressure from a urinal. The true nature of this narrowing must be recognized to avoid misinterpretation.
