    • An ultrasound gel is provided for use with internal ultrasound imaging and/or therapy. The gel can have acoustic properties that can closely match a soft tissue to be imaged/treated and can be of a high viscosity that is maintained at body temperature. In some embodiments, the gel can act as a lubricant and, although water based, can be hydrophobic and not dissolve in bodily fluids. In some embodiments, the gel can be sterile, safe for ingestion, safe for application over mucous membranes, and include a preservative. In order to achieve sterility while maintaining a desired viscosity range, the gel can include a viscosity stabilising agent such as a viscosity protection agent for protection from radiation induced breakdown. In some embodiments, methods of altering or maintaining the viscosity of a gel is provided.
    • 提供用于内部超声成像和/或治疗的超声凝胶。 该凝胶可以具有与待成像/处理的软组织紧密匹配的声学特性,并且可以具有保持在体温下的高粘度。 在一些实施方案中,凝胶可以充当润滑剂,并且虽然基于水,但可以是疏水性的并且不溶于体液。 在一些实施方案中,凝胶可以是无菌的,对于摄取是安全的,可安全地施用于粘膜上,并且包括防腐剂。 为了在保持期望的粘度范围的同时实现无菌性,所述凝胶可以包括粘度稳定剂,例如用于防止辐射引起的破坏的粘度保护剂。 在一些实施方案中,提供了改变或维持凝胶粘度的方法。
