Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Nanosecond laser
Patients with unwanted tattoos who plan a nanosecond laser treatment will be recruited for measurements using a multiphoton-tomography system.
nanosecond laser treatment + measurement with a multiphoton tomography system
Patients with unwanted tattoos who plan a laser treatment will be recruited for measurements using a multiphoton-tomography system. These are scheduled 6 weeks and 12 weeks post-treatment.
Picosecond laser
Patients with unwanted tattoos who plan a picosecond laser treatment will be recruited for measurements using a multiphoton-tomography system.
picosecond laser treatment + measurement with a multiphoton tomography system
Patients with unwanted tattoos who plan a laser treatment will be recruited for measurements using a multiphoton-tomography system. These are scheduled 6 weeks and 12 weeks post-treatment.
