Abstract

The invention discloses a photoacoustic detection device for guiding laser therapy, which is characterized by comprising: a laser for irradiating an object to be irradiated; The transmission medium between the irradiated objects collects the excitation photoacoustic signal generated by the irradiated object; the signal acquisition device is used to collect the excitation photoacoustic signal output by the ultrasonic transducer and average it; the control unit is used to collect the signal collected by the signal acquisition device. The excitation photoacoustic signal is analyzed to judge the effect and stage of laser treatment.

Description

technical field [0001] The invention relates to a device for monitoring the effect of laser treatment and timely feedback during laser treatment. Background technique [0002] Due to factors such as environment and life pressure, skin-related lesions and diseases have attracted more and more attention and attention. Such lesions and diseases can currently be treated and eliminated by means such as laser therapy. Laser treatment methods on the market can be mainly divided into two categories: ablative and non-ablative. The basic principle is the theory of selective photothermal separation, which enables the target chromophore to absorb the photons emitted by the laser device, and the light energy absorbed by the photons is converted into heat, and the thermal damage caused is limited to the selected tissue. Pigment fragments are removed from the body by metabolism. Here it can be found that the laser transmission of the selective photothermolysis is the same as the light e...
