Abstract: Provided is a method of improving a blood flow in a subject's brain, the method including noninvasively sequentially delivering light energy light having a wavelength of about 810 nm to about 870 nm toward blood vessels in an occipital lobe, a temporal lobe, a frontal lobe, and a parietal lobe of the subject along a blood flow starting from one portion of a carotid artery of a subject.

Abstract: The invention relates to a method and apparatus for multipulse laser treatments on a spot target by using a CO2 laser system and a laser beam scanner attached at the end of the delivery system. The laser system is controlled to emit a laser macropulse consisting of a series of micropulses with pulse durations in the range of microseconds to a few milliseconds. The first group of pulses is delivered to cause minimal thermal damage to the peripheral area in the epidermis and dermis, while creating a pinhole epidermal window down into the dermis, through which the subsequent pulses, which are longer in pulse duration and lower in energy, deliberately create thermal diffusion through conducted heat to create thermal damage in the targeted area of the dermis.
