    Abstract: A method of imaging a site of interest in a body using an ultrasound probe comprising a plurality of ultrasound transducer elements comprises obtaining an ultrasound image of a pass zone between the ultrasound probe and the site of interest. The image includes the site of interest and a plurality of tissue regions in a pass zone between the site of interest and the ultrasound probe. Boundaries of a selected tissue region in the pass zone are determined from the image. Focusing delay times are then computed for each ultrasound transducer element based in part on the speed of sound in the selected tissue region other than an average speed of sound in body tissue, and the boundaries of the selected tissue region. Preferably, a speed about the speed of sound in the selected tissue region is used and more preferably the speed of sound in the selected tissue region is used. Refraction may be considered, as well. Ultrasound imaging of the site of interest is then conducted employing the computed delay times. Fat and bone tissue regions are typically selected if present. Other tissue regions may be selected, as well. The boundaries of the tissue region or regions may be determined by segmentation. Tissue inhomogeneity is thereby compensated for, improving image contrast resolution. Ultrasound imaging systems and software are also disclosed. A new ultrasound probe comprising high and low frequency transducer elements is also disclosed.

    Abstract translation: 使用包括多个超声换能器元件的超声波探头在身体中成像感兴趣的位置的方法包括获得超声波探头与感兴趣部位之间的通过区域的超声波图像。 图像包括感兴趣的位置和感兴趣部位与超声波探头之间的通过区域中的多个组织区域。 从图像中确定通过区域中所选择的组织区域的边界。 然后，部分地基于除了身体组织中的平均声速和所选择的组织区域的边界之外的所选择的组织区域中的声速来计算每个超声换能器元件的聚焦延迟时间。 优选地，使用围绕所选择的组织区域中的声速的速度，并且更优选地使用所选择的组织区域中的声音速度。 也可以考虑折射。 然后使用计算的延迟时间进行感兴趣位点的超声成像。 通常选择脂肪和骨组织区域（如果存在）。 也可以选择其他组织区域。 可以通过分割来确定组织区域或区域的边界。 从而补偿组织不均匀性，改善图像对比度分辨率。 还公开了超声成像系统和软件。 还公开了一种包括高频和低频换能器元件的新型超声波探头。

    Abstract: Skull inhomogeneity may be quantified in accordance with the skull density measured in skull images acquired using a conventional imager; the quantified inhomogeneity may then be used to determine whether the patient is suitable for ultrasound treatment and/or determine parameters associated with the ultrasound transducer for optimizing transskull ultrasound treatment.

    Abstract: A thermal treatment system including a heat applying element for generating thermal doses for ablating a target mass in a patient, a controller for controlling thermal dose properties of the heat applying element, an imager for providing preliminary images of the target mass and thermal images during the treatment, and a planner for automatically constructing a treatment plan, comprising a series of treatment sites that are each represented by a set of thermal dose properties. The planner automatically constructs the treatment plan based on input information including one or more of a volume of the target mass, a distance from a skin surface of the patient to the target mass, a set of default thermal dose prediction properties, a set of user specified thermal dose prediction properties, physical properties of the heat applying elements, and images provided by the imager. The default thermal dose prediction properties are preferably based on a type of clinical application and include at least one of thermal dose threshold, thermal dose prediction algorithm, maximum allowed energy for each thermal dose, thermal dose duration for each treatment site, cooling time between thermal doses, and electrical properties for the heat applying element. The user specified thermal dose prediction properties preferably include at least one or more of overrides for any default thermal dose prediction properties, treatment site grid density; and thermal dose prediction properties not specified as default thermal dose prediction properties from the group comprised of thermal dose threshold, thermal dose prediction algorithm, maximum allowed energy for each thermal dose, thermal dose duration for each treatment site cooling time between thermal doses, and electrical properties for the heat applying element.
