Abstract: The invention is directed to a method and apparatus for timing calibration in a PET scanner. According to one embodiment, the invention relates to a method for timing calibration in a PET scanner having a plurality of scintillator blocks. The method comprises: detecting, in a first scintillator block, a first radiation event, wherein the first scintillator block time-stamps the first radiation event; detecting, in a second scintillator block that is adjacent to the first scintillator block, a second radiation event that corresponds to the first radiation event, wherein the second scintillator block time-stamps the second radiation event; and determining a timing characteristic of the first scintillator block with respect to the second scintillator block based on a comparison between the time-stamps of the first radiation event and the second radiation event.

Abstract: A method for producing preferential damage to hair exiting mammalian skin. A agent having an average diameter for enabling the agent to penetrate the hair duct is selected. The agent is designed to attach to, or become physically incorporated into, the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent has an electromagnetic radiation absorption characteristic which enables the agent to absorb a first wavelength of electromagnetic radiation from a skin-penetrating electromagnetic radiation source, such as a laser. The agent is applied to the skin so that the agent penetrates the skin and attaches to or becomes physically incorporated into the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent is exposed to the first wavelength of electromagnetic radiation and absorbs the first wavelength of electromagnetic radiation.
