    • Apparatus for controlling high intensity focused ultrasound (HIFU) tissue treatment includes at least one ultrasound transducer (128), a first device (130) coupled to the at least one transducer (128) for driving the at least one transducer (128), and a second device (132) coupled to the first device (130) to control the first device (130) and to the at least one transducer (128) to receive data of return echoes received by the at least one transducer (128). The second device (132) controls the first device (130) to: (a) develop data of the untreated tissue; (b) store the data of the untreated tissue; (c) treat the tissue to a cycle of HIFU from the at least one transducer (128); (d) develop data of cycle (c); (e) compare the data developed at (d) to the data stored at (b); (f) repeat steps (c) - (e) until a desired value of a tissue modification parameter ( alpha ) is obtained; and (g) provide an indication once the desired value of the tissue modification parameter ( alpha ) has been obtained. A method for controlling high intensity focused ultrasound (HIFU) tissue treatment thus includes: (a) developing data of the untreated tissue; (b) storing the data of the untreated tissue; (c) treating the tissue to a cycle of HIFU from at least one ultrasound treatment transducer (128); (d) developing data of cycle (c); (e) comparing the data developed at (d) to the data stored at (b); (f) repeating steps (c) - (e) until a desired value of a tissue modification parameter ( alpha ) is obtained; and, (g) terminating the treatment.
    • 用于控制高强度聚焦超声(HIFU)组织治疗的装置包括至少一个超声换能器(128),耦合到所述至少一个换能器(128)的用于驱动所述至少一个换能器(128)的第一装置(130),以及 耦合到所述第一设备(130)以控制所述第一设备(130)和所述至少一个换能器(128)以接收由所述至少一个换能器(128)接收的返回回波的数据的第二设备(132)。 第二装置(132)控制第一装置(130)以:(a)显影未经处理的组织的数据; (b)存储未处理组织的数据; (c)将所述组织从所述至少一个换能器(128)处理到HIFU的循环; (d)制定周期(c)的数据; (e)将在(d)开发的数据与存储在(b)的数据相比较; (f)重复步骤(c) - (e),直到获得组织修饰参数(α)的期望值; 并且(g)一旦获得组织修饰参数(α)的期望值,就提供指示。 因此,用于控制高强度聚焦超声(HIFU)组织处理的方法包括:(a)显影未处理组织的数据; (b)存储未处理组织的数据; (c)从至少一个超声治疗换能器(128)将所述组织处理至HIFU的循环; (d)制定周期(c)的数据; (e)将(d)开发的数据与存储在(b)的数据进行比较; (f)重复步骤(c) - (e),直到获得组织修饰参数(α)的期望值; 和(g)终止治疗。
