Sarah Barrow says she is aiming to reach the final in the 10m platform event at the 2016 Olympics.
The 27-year-old overcame two years of chronic shin problems to secure her qualification.
She came fifth in the synchro at the 2012 Games in London and will make her Olympic debut in the individual event.
"It's been a long two years but I've worked with physios and we've got everything together at the right time," she told BBC Sport.
"It's been fairly difficult with my legs - having to stop and start again, having two operations and thinking it would be over, and then having stress fractures and having to compete with them," added Barrow, who has also had to contend with a non-cancerous tumour.
"My goal is get into an Olympic final - if I can get to that who knows in the final, whatever happens."
Team GB's best-ever diving medal haul from a single Olympics is two from the 1960 Rome Games, with Tom Daley's bronze their only medal four years ago.
"It's probably fair to say that we have the strongest Olympic team that we've ever had for the sport of diving," said coach Andy Banks.
"We're obviously hoping that we can hold it together, compete at the very highest level and hopefully come away as a multi-medal sport."
