Legacy MIRD used organ-level S-values (absorbed dose per unit cumulated activity). MIRD237 introduces computed via Monte Carlo simulations on high-resolution CT or MRI. This allows dose mapping at 2-4 mm³ resolution. Why it’s better: You can now see hot spots within a tumor—areas that legacy models smoothed into a single average dose.
"Better means breaking compatibility." Reality: As noted, backward compatibility is a core pillar. You can run better modes with new devices while talking legacy with old ones. mird237 better
“Better saved my babies,” she whispered that night, crying. Legacy MIRD used organ-level S-values (absorbed dose per
“mird237 better” has begun appearing outside its original technical context. Project managers use it to mean “a solution that is not the absolute fastest, but the most reliably understandable under pressure.” Educators use it to mean “a method that students can debug themselves.” The term is evolving into shorthand for — the kind of better that accounts for human exhaustion, edge cases, and Monday morning emergencies. Why it’s better: You can now see hot
