Embodiment Construction

[0048] figure 1 Apparatus 100 is depicted as a combined imaging and therapy system by way of an illustrative and non-limiting example. It includes a controller 104 , a receiving element (REB) based registration module 108 and / or a microbubble activity (MAB) based registration module 112 . Dashed lines 116 to the REB registration module and 120 to the MAB registration module indicate that the two modules 104, 108 are alternative or capable of operating in the same device. Again, part of the apparatus 100 is the cavity processor 124 mentioned above, and the same as the Browning application figure 1 A corresponding primary ultrasound system 128 with the variations discussed above. Therefore, the primary ultrasound system 128 contains the Browning application's figure 1 User interface 38, display 40, etc. in. Additional parts of the device 100 are the imaging subsystem 132 and its complementary detachable therapy subsystem 136 . The first diagrammatic line segment 140 can be ...

Abstract

An apparatus for ultrasound irradiation of a body part (208) includes a first ultrasound transducer (216),and a second ultrasound transducer (212) mounted oppositely, and is configured: a) such that at least two ultrasound receiving elements, for determining a relative orientation of the first to the second transducer, are attached to the first transducer; b) for a beam, from the first transducer, causing cavitation, and / or bubble destruction of systemically circulating microbubbles, within the body part; or c) both with the attached elements and for the causing. The apparatus registers, with said first transducer, the second transducer, by using as a reference respectively the features a) and / or b). A detachable subsystem includes either a therapy or imaging transducer,to form a combination imaging and therapy system, the subsystem being configured for removable coupling to correspondingly an imaging or therapy subsystem comprising a head frame(204) to which is mounted an imaging or therapy transducer, the imaging or therapy subsystem for registering the imaging or therapy transducer, one to the other, by the above method.

Description

technical field [0001] The present invention relates to registering one ultrasound transducer to another, and more particularly to registering transducers mounted on opposite sides of a body part. Background technique [0002] It has been known for many years that ultrasound in combination with thrombolytic drugs, especially tissue plasminogen activator (tPA), can aid in the dissolution of thrombi that cause ischemic stroke. However, tPA has many side effects and can be fatal when used in hemorrhagic (hemorrhagic) stroke patients, and thus requires CT to rule out bleeding before its use. Ultrasound in combination with microbubble contrast agents has also been shown to dissolve blood clots with potentially fewer adverse effects. This effect is commonly referred to as sonothrombolysis (STL). [0003] Transcranial imaging has long been used to diagnose cerebrovascular disease, such as stroke using diagnostic ultrasound systems. A stroke almost always occurs on one side of th...
