In vivo drug screening in human skin using femtosecond laser multiphoton tomography.
The novel femtosecond laser multiphoton imaging system DermaInspect forin vivotomography of human skin was used to study the diffusion and intradermal accumulation of topically applied cosmetic and pharmaceutical components. Near-infrared 80 MHz picojoule femtosecond laser pulses were employed to excite endogenous fluorophores and fluorescent components of a variety of ointments via a two-photo...
متن کاملUse of multiphoton tomography and fluorescence lifetime imaging to investigate skin pigmentation in vivo.
There is a growing body of literature showing the usefulness of multiphoton tomography (MPT) and fluorescence lifetime imaging for in situ characterization of skin constituents and the ensuing development of noninvasive diagnostic tools against skin diseases. Melanin and pigmentation-associated skin cancers constitute some of the major applications. We show that MPT and fluorescence lifetime im...
متن کاملIn vivo assessment of human skin aging by multiphoton laser scanning tomography.
Changes of dermal collagen and elastin content are characteristic for skin aging as well as for pathological skin conditions. To evaluate these changes, we used in vivo multiphoton laser tomography to measure two-photon excited autofluorescence (AF) and second harmonic generation (SHG). We tested 18 patients of all ages and calculated the SHG-to-AF aging index of dermis (SAAID). We observed a n...
متن کاملClinical application of multiphoton tomography in combination with confocal laser scanning microscopy for in vivo evaluation of skin diseases.
Multiphoton tomography (MPT) is an in vivo imaging technique with very high spatial resolution and efforts are made to combine MPT with other non-invasive imaging methods. The goals of the present study were the description of the features of different dermatological entities as seen in MPT and confocal laser scanning microscopy (CLSM) comparison of these two novel techniques and the 'classical...
متن کاملSkin in vivo Dosimetry in Radiotherapy
Introduction: Due to the prevalence of skin problems in patients after radiotherapy, skin dose measuring is importance. Content: Skin in vivo dosimetry means measuring the patient's (or phantom) skin dose during radiotherapy. According to the ICRP 59, the dose at the depth of 0.07 mm is known as a skin dose. The most radiosensitive epidermis cells are located...
