The eight-time world champion and two-time Olympian is hoping doctors will clear her to return to the bike after a horrific 18 months.
Buchanan has had three operations on her sternum to repair the damage after an off-road accident at the end of 2017, which resulted in life-threatening injuries.
But the Canberra BMX star is hopeful she will get good news and be ready to increase her training load less than a year before the Tokyo opening ceremony.
"Tokyo is a massive goal and this next [scan] is a big milestone towards seeing if that goal of mine is achievable," Buchanan said.
"I would love to compete for Australia at my third Olympic Games. I will be leaving no stone unturned in my rebuild and return to racing."
Buchanan almost died after the accident near Cooma, escaping with her life by suffering a crushed sternum, collapsed lungs and dangerous bleeding around her heart.
Buchanan returned to competition riding at the end of last year, but she felt uncomfortable "popping and grinding" in her chest when the plates and wires moved.
It delayed her full-time comeback, although the 28-year-old has vowed to do everything in her power to achieve her goal of winning an Olympic medal.
"I am on a road bike and [doing] a gym rebuild program now but I am still limiting chest and spine load," Buchanan said.
"I am hoping to be on BMX and mountain bike [soon], and cleared for more load [training] when I have a scan next week]."
Buchanan has been one of Australia's leading medal contenders at the past two Olympics, but she hasn't been able to breakthrough for a podium finish in the 30 seconds of mayhem on the BMX track.
An Olympic medal table predictions says Australia will finish sixth on the medal tally next year, with forecasts of 43 medals - 13 gold, 15 silver and 15 bronze.
Canberra javelin thrower Kelsey-Lee Barber is making her move to rise up the world rankings to be a contender in Tokyo, throwing a massive personal best in Europe two weeks ago.
Long-distance runner Keely Small will be chasing her first Olympic selection after making her Commonwealth Games debut last year, while Lauren Wells and Melissa Breen will also be hoping to compete at a third Games.
Cyclists Chloe Hosking, Gracie Elvin, Rebecca McConnell, Dan McConnell and Michael Matthews could earn selection Sharni Williams will be hoping for back to back rugby sevens gold medals.
Rowers Cara Grzeskowiak, Luke Letcher, Caleb Antill and Angus Moore have been competing for Australian teams in Europe and will have their eyes on securing a Tokyo ticket.
ACT Brumbies flanker Tom Cusack is also hoping to compete at his second Olympics, but he will have to juggle Australian sevens duties and Super Rugby matches over the next 12 months.
Cusack, picked in the all-star team at the Rio Olympics, will spend the rest of this year training with the men's sevens team before returning to Brumbies training in January.
