The AFL will test Hawk-Eye goal technology at the MCG this week, starting with Friday night's clash between Collingwood and Carlton.

Brought in from the UK, the technology will be tested, but not used to adjudicate scores in the four MCG games.

The AFL's Mark Evans told 3AW radio: "It is a piece of technology that allows the person reviewing goal scores to manipulate the vision themselves. All the vision comes up on the one screen, and you can exit some and just focus on one or two [angles]".

The technology allows multiple angles, which can then be compared to each other, to determine, for example, if the ball has been touched before passing the goal line, or whether it hit the goal post.

The AFL's goal review system has been a constant source of controversy since its introduction last year. It was brought in after goal-umpiring mistakes, starting perhaps with a point kicked by Geelong Tom Hawkins in the 2009 grand final against St Kilda, which was deemed a goal.
