Abstract: The present disclosure is directed to a phototherapeutic apparatus for focused UVB radiation and vitamin D synthesis and associated systems methods. In one embodiment a phototherapeutic apparatus can include a housing at least partially defining an irradiation zone, and an ultraviolet (UV) radiation source carried by the housing. The irradiation zone can be configured to accommodate at least a portion of a human patient. The phototherapeutic apparatus can further include a filter between the UV radiation source and the irradiation zone. The filter can be configured to at least substantially remove UV radiation outside of a predetermined spectrum centered at about 297 nm and having a bandwidth of at most 10 nm.

Abstract: A phototherapy system can provide functions such as user account management, skin type evaluation, treatment parameter determinations and adjustments, treatment blocking or warnings for some hazard prevention, treatment education and guidance, session records access, treatment regime determination, scheduling, and converting treatment parameter determinations into kiosk controls. The phototherapy system functions can be performed based on user input, records of user data, guidelines and algorithms for treatment parameter selection, direct measurements, etc. These data sources can be accessed or implemented though one or more of: a phototherapy kiosk, a personal computing device, a server system, a third-party system, or any combination thereof. An interactive user interface can be used though any of these devices to facilitate user control and user feedback for the phototherapy system.

Abstract: Dynamic dosing systems for phototherapy and associated devices, systems, and methods are disclosed herein. In some embodiments, a dynamic dosing phototherapy system can include a self-service phototherapy kiosk (“SPK”) configured to emit UV radiation, a user interface communicatively coupled to the SPK, and a dynamic dosing system communicatively coupled to the user interface and the SPK. The dynamic dosing system can determine initial, user-specific parameters specific to define a first individual phototherapy protocol, and then determine adjustments to the initial parameters and the first individual phototherapy protocol based on user inputs related to erythema response to a previous phototherapy treatment session. The SPK can deliver UV radiation to a user in accordance with the first individual phototherapy protocol and/or an adjusted, second phototherapy protocol that takes into account the user's erythema response.

Abstract: A phototherapeutic system in accordance with an embodiment of the present technology includes a housing at least partially defining an irradiation zone configured to accommodate at least a portion of a human subject. The system further comprises an ultraviolet (UV) radiation source configured to direct UV radiation along a radiation path extending from the radiation source to the irradiation zone. The radiation source includes a concentrated source at which UV radiation is generated, and a collimating reflector (or lens) configured to reflect (or refract) the UV radiation and thereby increase collimation of the UV radiation. The system still further comprises a filter, a spreader, and a collimator disposed successively farther downstream from the radiation source along the radiation path. The spreader and the collimator respectively decrease and increase collimation of the UV radiation before the UV radiation reaches the subject.

Abstract: The present disclosure is directed to systems and methods for increased vitamin D3 production during phototherapy treatments, in one embodiment, a phototherapeutic system can include an ultraviolet (UV) source directed toward an irradiation zone and a filter between the UV source and the irradiation zone. The UV source can be configured to deliver a predetermined energy ieve! during a phototherapy session. The filter can at least substantially remove UV radiation outside of a predetermined wavelength spectrum. The predetermined spectrum can have a bandwidth of at most 10 nm and can be focused at a wavelength corresponding to a maximum on a vitamin D3 phototherapy action spectrum for the predetermined energy level.
