A change to international cricket's Decision Review System (DRS) will come into effect from October, making it easier for fielding teams to overturn not-out decisions, the ICC has confirmed.
At present, for an on-field lbw decision of 'not out' to be changed, half of the ball must be projected to hit a zone between the respective centres of off stump and leg stump.
However, that area will now increase, "changing to a zone bordered by the outside of off and leg stumps".
The impending amendment was announced following the ICC's annual conference in Edinburgh, which concluded on Saturday.
ICC chief executive David Richardson said testing at the Massachusetts Institute of Technology (MIT) had shown ball-tracking technology to be more accurate than first thought.
Richardson was quoted by ESPNCricinfo as saying: "For that reason we are able to safely reduce the margin of uncertainty or the 'umpire's call' as we refer to.
"Ian Botham [a Sky Sports commentator and former England captain] and all these experts were always saying 'how can that be given not out? That ball was crashing into the leg stump'. But because the middle of the ball was just marginally, one millimetre, to the right of centre of the stump, then the umpire's decision wasn't reversed.
"So what we have done really is just made that margin of uncertainty slightly bigger. Now the middle of the ball must be in line with the stump, which means half of the ball hitting the stump is going to be given out in the future. That is the simple change."
The ICC also discussed the calling of no-balls, a controversial topic that has prompted much debate in recent years.
A statement from the governing body read: "The ICC will arrange a trial over coming months to better understand whether the third umpire could use instant replays to call no-balls more accurately.
"The trial is likely to be staged during one of the upcoming ODI series, and the third umpire will judge no-balls within a few seconds of the ball being delivered and communicate this to the on-field umpire. Further details relating to the trial will be announced once finalised."
