Great Britain's Kat Driscoll narrowly missed out on qualifying for the women's individual trampoline final at the North Greenwich arena after finishing in ninth place.
Driscoll, 26, scored 46.335 in her compulsory routine before a voluntary routine of 54.650, but it was not enough to finish in the top eight showdown for medal positions as she fell short by just 0.010 of a mark.
Defending Olympic gold medallist, China's He Wenna, Beijing silver medallist Karen Cockburn of Canada, world champion Rosannagh MacLennan and Athens bronze medallist Huang Shanshan all progressed into the final, with He topping qualification after recording a total of 105.550.
It is still Britain's best finish in Olympic trampoline, which made its debut at the 2000 Sydney Games, beating Claire Wright's 10th-place finish in Beijing four years ago.
