DOI 10.1109/icsens.2016.7808539
Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

We report the real-time measurement of intra-tissue parenchymal pressure during laser ablation (LA). Pressure detection is performed with an extrinsic Fabry-Perot interferometry (EFPI) probe, fabricated with a biocompatible all-glass design. Experiments have been performed with solid-state laser ablator, recording a peak pressure of 71.6 kPa. The pressure measurement methodology may allow fine control of LA procedure.
