Embodiment Construction

[0155] Like numbered elements in these figures are equivalent elements or perform the same function. Elements that have been discussed previously may not necessarily be discussed in later figures if the function is equivalent.

[0156] figure 1 A flowchart illustrating a method according to an embodiment of the invention is shown. In step 100, the method starts. Next in step 102, real-time medical data is received. Next in step 104, the electronically adjustable focus is adjusted to target the moving target using the real-time medical data. Next in step 106, ultrasonic treatment is performed on the target when the moving target is within the beam deflection zone. This may also include sonicating a portion of the target within the beam deflection zone. Box 108 is a decision box. If sonication is not complete, the method returns to step 102 . Steps 102-106 are repeated in a continuous loop until sonication is complete. In this way, real-time medical data is received and ...

Abstract

A therapeutic apparatus (300, 400, 500) comprising a high intensity focused ultrasound system (302) comprising an ultrasound transducer (306). The ultrasound transducer has an electronically adjustable focus (318). The high intensity focused ultrasound system has a beam deflection zone (322, 608, 704, 1010). The intensity of ultrasound at the electronically adjustable focus divided by the acoustic power emitted is above a predetermined threshold (606, 1008) within the beam deflection zone. The therapeutic apparatus further comprises a processor (328) for controlling the therapeutic apparatus. Execution of machine executable instructions (350, 352, 354) causes the processor to: receive (102, 202) real time medical data (342, 424, 506) descriptive of the location of a moving target (320, 802); adjust (104, 204) the electronically adjustable focus to target the moving target using the real time medical data; and sonicate (106, 206) the moving target when the moving target is within the beam deflection zone.

Description

technical field [0001] The present invention relates to high-intensity focused ultrasound, in particular to ultrasonic treatment of moving objects. Background technique [0002] Ultrasound is rapidly becoming the desired modality for certain therapeutic interventions. Specifically, the use of high-intensity focused ultrasound is currently being used as a thermal therapeutic intervention for uterine fibroids and has been examined for use in the management of liver, brain, prostate and other cancerous lesions. Ultrasound therapy for tissue ablation works by sonicating the tissue of interest with high-intensity ultrasound, which is absorbed and converted into heat, increasing the temperature of the tissue. As the temperature increases, coagulation necrosis of the tissue can occur, resulting in immediate cell death. Transducers for therapy can be external to the body or inserted into the body, eg, through a blood vessel, urethra, rectum, or the like. [0003] In high intensit...
