Acousto-optic integrated imaging and treatment system and method

Abstract

The invention discloses an acousto-optic integrated imaging and treatment system and method. The system comprises an imaging unit, a laser treatment unit and an ultrasonic treatment unit, wherein theimaging unit comprises a pulse laser generator and an ultrasonic diagnosis probe; the pulse laser generator is used for emitting pulse laser to an interested area and triggering an acousto-optic effect, and the ultrasonic diagnosis probe is used for receiving ultrasonic waves generated by triggering of the pulse laser to form an acousto-electric signal; the laser treatment unit is used for emitting laser to realize photothermal therapy and possible light immunotherapy; and the ultrasonic treatment unit is used for emitting sound waves to realize thermal ablation therapy and possible thermal immunotherapy. According to the system and the method, two imaging modes including ultrasonic imaging and acousto-optic imaging are integrated, multi-mode imaging is realized, and focus positioning is more accurate; multiple treatment modes are integrated, the disease treatment efficiency is improved, and a powerful tool is provided for preoperative diagnosis, residual focus evaluation, real-time curative effect monitoring and prognosis prediction of diseases.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an acousto-optic integrated imaging and treatment system and method. Background technique [0002] As an effective form of energy transfer, ultrasound has played a huge role in disease imaging diagnosis, hyperthermia, drug-mediated, and gene delivery. Laser light can also be used for medical diagnosis and treatment due to its stable propagation direction, high energy, and pure color. At present, there are disease diagnosis and treatment models that use ultrasound and laser as energy sources. For example, thermal ablation therapy using high-energy focused ultrasound as a treatment method uses ultrasonic mechanical waves to precisely focus on the lesion, generating instantaneous high temperatures of 60°C-100°C. To achieve coagulation necrosis, and then to achieve non-invasive removal of the lesion. Laser-mediated photothermal therapy is to use materials with high photothermal conve...
