摘要:
Wirelessly powered photodynamic therapy devices are disclosed and systems and methods using such devices are also disclosed. In an embodiment, a photodynamic therapy system comprises: an implantable illumination device comprising a light source configured to emit light having a spectrum which overlaps with an absorption peak of an absorption target and a receiver antenna coupled to the light source and configured to extract power from a radiofrequency power signal incident on the implantable illumination device; and a transmitter comprising an antenna, a powering module configured to generate a drive signal which causes the antenna to generate the radiofrequency power signal, and a dosimetry module coupled to the antenna and configured to detect a radiofrequency signal backscattered from the implantable illumination device and determine an indication of the power extracted by the implantable illumination device from the radiofrequency signal backscattered from the implantable illumination device.
