We are investigating use of methylene blue photodynamic therapy (MB-PDT) to treat deep tissue abscesses. Monte Carlo simulations incorporating patient-specific CT images (60 subjects) were utilized to examine the effect of optical properties on the generation of patient-specific treatment plans. We investigated the influence of varying abscess wall absorption and Intralipid-induced scattering within the cavity on threshold optical power and eligibility for MB-PDT. When Intralipid concentration and delivered optical power were optimized simultaneously for each patient, eligibility for MB-PDT increased greatly from 42% to 92%, though this was diminished by the presence of absorption within the cavity.
