摘要:
The present disclosure is directed to systems and methods for targeted UVB phototherapy for dermatologic disorders and other indications. In one embodiment, a phototherapeutic system can include a radiation source configured to emit light. At least 75% of the light emitted by the radiation source can have wavelength with a bandwidth between 298 nm and 307 nm. The phototherapeutic system can also include a controller operably connected to the radiation source and configured to determine a dosage for a phototherapy session. Dosage can correspond to a product of the intensity of the radiation source and an exposure time of the radiation source, and may have an upper bound less than 1 minimal erythema dose (MED). Delivery of the dose of phototherapy can stimulate production of calcitriol and vitamin D3 in the user's skin and can provide an immune response to treat a dermatological disorder.

The invention relates generally to treatment of solid cancers. More particularly, the invention relates to a multi-field charged particle cancer therapy method and apparatus coordinated with negative ion beam creation, ion beam focusing, charged particle acceleration, patient rotation, and/or patient respiration. Preferably, the charged particle therapy is performed on a patient in a partially immobilized and repositionable position. Proton delivery is preferably timed to patient respiration via control of charged particle beam injection, acceleration, and/or targeting methods and apparatus.

The invention relates to a device for irradiating an object, in particular human skin, with UV light. Said device comprises a UV light source and an irradiation head containing imaging optics, UV light being projected from the irradiation head onto the object. According to the invention, the irradiation head can be adjusted by means of a motor, the UV light source is situated in a separate light source housing outside the irradiation head and at least one flexible fibre optic is located between the light source housing and the irradiation head, said fibre optic being used to feed UV light from the UV light source to the irradiation head.

The present disclosure is directed to systems and methods for targeted UVB phototherapy for treating autoimmune disorders and other indications. In one embodiment, a phototherapeutic system can include a radiation source configured to emit light. At least 75% of the light emitted by the radiation source can have a target wavelength range with a bandwidth between 298 nm and 307 nm. The phototherapeutic system can also include a controller operably connected to the radiation source and configured to determine a dosage for a phototherapy session. Dosage can correspond to a product of the intensity of the radiation source and an exposure time of the radiation source, and may have an upper bound less than 1 minimal erythema dose (MED). Delivery of the dose of phototherapy can stimulate an immune response to treat an autoimmune disorder.
摘要:
A device for circumscribing a target site with a beam. The target site is located within a target body. The path of the beam is varied rotationally so as to form a cone with an isocenter at the cone's apex. The isocenter is fixed on the approximate center of the target site. The target body is rotated about a vertical axis passing approximately through the center of the target site, and the rates of rotation of the beam path and body, respectively correspond so that the beam intersects an axis passing through the target site at an approximately constant angle.

摘要:
A support system for breast irradiation including a turntable for supporting and rotating a patient about a generally vertical rotational axis, a body-leaning support for supporting the patient leaning thereupon throughout rotation of the patient about the vertical rotational axis, and a radiation shield arranged for shielding non-breast anatomy of the patient from stray radiation, wherein the body-leaning support and the radiation shield are separated from each other by a gap in which breasts of the patient are placeable for irradiation by a horizontal radiation beam.
