项目摘要

DESCRIPTION (provided by applicant): Abscesses are infected walled-off fluid collections of pus and bacteria, and represent a ubiquitous global healthcare problem. They are common sequelae of surgery, infections or disease, and can affect any part of the body. Current standard of care includes hospitalization, antibiotics and drainage of the abscess with a catheter. The bacteria in puss are susceptible to both thermal and mechanical damage. High Intensity Focused Ultrasound (HIFU) can generate localized heating and cavitation, and is a potential noninvasive means to treat abscesses by exploiting one or both mechanisms. The significance of this proposal is that noninvasive treatment of reachable abscesses using ultrasound therapy under ultrasound guidance is better for the patient because it is noninvasive, allows treatment of small abscesses, has less procedural pain, requires no catheter management, there is no potential tract for new infections, and no need for CT/fluoro imaging radiation.

描述（由适用提供）：脓肿是脓液和细菌的感染围绕液体收集，代表着无处不在的全球医疗保健问题。它们是手术，感染或疾病的常见后遗症，可能会影响身体的任何部位。当前的护理标准包括住院，抗生素和脓肿的排水。脓液中的细菌易受热和机械损伤。高强度聚焦超声（HIFU）可以产生局部加热和空化，并且是通过利用一种或两种机制来治疗脓肿的潜在无创手段。该提议的意义在于，在超声指导下使用超声治疗的可及脓肿的无创治疗对患者来说更好，因为它是无创的，允许治疗小脓肿，更少的手术疼痛，不需要导管管理，不需要导管治疗，没有潜在的感染，并且不需要新的ct/fluororo ct/fluororo Imaforo Imagiotion。
