A robotic arm comprising an operation end, a base, a sensor unit and a control unit is provided. The operation end is connected to the base, and the operation end is configured to reach an operational area. The sensor unit provides a sensor signal according to the force applied by or the motion of an operator. When the operation end reaches the operational area, the control unit sets a fixed position on the robotic arm between the base and the operation end. When the sensor signal from the operator fulfills a default condition, the control unit moves the robotic arm away from the operator, without moving the fixed position on the robotic arm.

An ultrasound energy barrier for avoiding energy accumulation in a to-be-protected region during tumor treatment has a barrier element and a positioning element. The barrier element is attached to a body surface of an animal outside a to-be-protected region and a to-be-treated tumor in turn, the barrier element has an outline matched with the to-be-protected region to thus shield the to-be-protected region, so as to avoid energy accumulation in the to-be-protected region during an ultrasound focusing treatment of the to-be-treated tumor. The positioning element positioning the barrier element on the body surface during the ultrasound focusing treatment.

The present invention provides an acceleration and enhancement methods for ultrasound scatterer structure visualization. The method includes: obtaining an ultrasonic image, calculating all values of the ultrasonic signal points in each mwindow centered at a nsignal point to obtain a plurality of original statistical values ax, obtaining a plurality of mstatistical values by averaging value of original statistical values in the same window, calculating a plurality of mweighting values based on the statistical values by different weighting formulas, multiplying each weighting value with the original statistical values corresponding to the various size of windows, summing up to obtain an ultrasound structure scatterer value of the nultrasonic signal point, and generating an ultrasound scatterer structure image based on a matrix of the ultrasound scatterer values. The present invention further combined interpolation method can reduce the computation time and retain the 80% accuracy.

A non-invasive positioning system for determining the focus location of a HIFU device comprises a diagnostic ultrasound and the HIFU for ablating and removing tumor tissue. The imaging plane of the diagnostic ultrasound probe and the geometrical axis of a probe of the HIFU define an inclining angle during operation. When the imaging plane of the diagnostic ultrasound intersected to the focus of the HIFU transducer, a maximal convergent interference signals was obtained, so as to position the HIFU focus within tumors for precise ablation.
