Fat mass derivation device, method, and program

Patent US12588885B2, granted March 31, 2026, covers a device with at least one processor that derives fat mass distribution from first and second radiation images acquired with different energy distributions, then derives visceral fat mass distribution based on the shape of the fat mass distribution in cross-sections orthogonal to the body axis. The patent has 13 claims, was invented by Tomoyuki Takahashi, and was filed August 26, 2022 under Application No. 17822688.

Companies developing or using similar medical imaging technologies for body composition analysis should review the patent claims to assess potential infringement risks and evaluate whether licensing is necessary. The 20-year patent term provides FUJIFILM exclusivity through 2042. No immediate compliance obligations apply, but organizations should consult patent counsel for freedom-to-operate analysis.
