    Abstract: A phototherapy system having sensor(s) for detecting parameters associated with light generation by a light source and circuitry for modulating the light source based on the detected parameters. Also, a phototherapy system having a light guide interfacing with a light source at a connection point, an ambient light sensor, a connector light sensor for detecting (at the connection point) ambient light received by a light emitting pad that is directed into the light guide, and circuitry for determining whether the light guide is correctly connected to the light source based on a difference between the output of the ambient light source and the connector light sensor. Further, a phototherapy system including a light emitting pad having an identification tag and circuitry that modulates a light source based on the identification tag. Additionally, a phototherapy system including a casing encapsulating multiple light emitters and a light emitting pad.

    Abstract: According to an aspect, there is provided a hand-held skin treatment device (2) for applying light to skin of a subject to perform a treatment operation. The hand-held device (2) comprises a rigid main housing (4) accommodating a cooling unit (19); a first treatment head portion (12) coupled to the main housing (4) for performing the treatment operation on a first skin portion, wherein the first treatment head portion (12) comprises a first optical waveguide (16) having a first skin-contact surface (17) with a first total surface area, a first light source (14) for generating light and applying the light to the first skin portion via the first optical waveguide (16) and the first skin-contact surface (17), and a first heat sink (18) thermally coupled to the first light source (14) and to the cooling unit (19); a second treatment head portion (20) for performing the treatment operation on a second skin portion adjacent to the first skin portion, wherein the second treatment head portion (20) comprises a second optical waveguide (24) having a second skin-contact surface (25) with a second total surface area, a second light source (22) for generating light and applying the light to the second skin portion via the second optical waveguide (24) and the second skin-contact surface (25), and a second heat sink (26) thermally coupled to the second light source (22); wherein the hand-held device (2) is operable in (i) a first configuration in which the first and second treatment head portions (12; 20) are in a first spatial arrangement relative to the main housing (4) such that, in an operational position of the main housing (4) relative to the skin, only the first skin-contact surface (17) is arranged in a treatment position relative to the main housing (4) such as to be able to contact the skin over the first total surface area; and (ii) a second configuration in which the second treatment head portion (20) is coupled to the main housing (4) and the second heat sink (26) is thermally coupled to the cooling unit (19), and in which the first and second treatment head portions (12; 20) are in a second spatial arrangement relative to the main housing (4), different from the first spatial arrangement, such that, in the operational position of the main housing (4), the first skin-contact surface (17) and the second skin-contact surface (25) are each arranged in a treatment position relative to the main housing (4) such as to be able to contact the skin over, respectively, the first total surface area and the second total surface area.

    Abstract: An interoperative light therapy apparatus and method are disclosed. The apparatus includes an excitation light source, a plurality of light emitting devices and a plurality of light detecting fibers, wherein the plurality of light emitting devices produce a fluorescence light in cancerous cells of a patient treated with a photosensitizing medication. The fluorescence light is collected by the plurality of detector fibers and a digital spatial image of the cancerous cells is produced. The digital spatial image is useful for targeting the cancerous cells in a subsequent resection procedure. An interoperative light therapy apparatus is disclosed that further include a therapy light source that can deliver therapy light to the cancerous cells using the digital spatial image in the subsequent resection procedure.
