摘要： For noninvasive treatment of tissue using high intensity focused ultrasound, composite imaging and therapy acoustic techniques are described. Embodiments include an integrated multi-functional confocal array and a strategy to perform both imaging and therapy simultaneously with this array by using coded excitation techniques with/without a notch filter. An exemplary array embodiment includes a triple-row phased array with one array in the center row for imaging and two arrays in the outer rows for therapy. Different types of piezoelectric materials and stack configurations may be employed to maximize the respective therapy and imaging functionalities. Reflected therapeutic signals that would otherwise corrupt the quality of imaging signals received by the center-row array can be mitigated or removed by use of the coding and/or a notch filter when B-mode images are formed during therapy. A 13-bit Barker code is preferred for implementing coded excitation, although other codes or compression techniques may be used.

摘要： A high frequency ultrasonic transducer may include a plurality of adjacent ultrasonic transducer elements. The adjacent transducer elements may be sized and configured so as to resonate at a frequency that is at least 15 MHz. The adjacent transducer elements may collectively form an aperture that is substantially convex along a lateral dimension spanning the cascaded width of the adjacent transducer elements. The aperture may be substantially concave along an elevation spanning the height of each of the transducer elements. The ultrasonic transducer and an associated transmitter system may be configured so as to enable ultrasound that is radiated from the plurality of the transducer elements to be focused on and to scan across locations that are no more than 30 millimeters from the aperture and that span across a field of view of at least 50 degrees without movement of the ultrasonic transducer or tissue during the scanning.

摘要： Various embodiments are described herein for a method, apparatus and system for performing multi-modal imaging using a common imaging probe having various modes of operation including a fluorescent (FL) imaging mode and at least one of an ultrasound (US) imaging mode, a photoacoustic (PA) imaging mode and a combined US/PA imaging mode. Molecular/functional information may be obtained from FL and PA imaging and anatomical information may be obtained from ultrasound (US) imaging. The system may be implemented to provide for images from each modality in real time as well as provide for co-registration of these images. Experimental results demonstrate that combining the imaging modalities does not significantly compromise the performance of each of the separate US, PA, and FL imaging techniques, while enabling multi-modality registration.

摘要： Provided is a method of dynamically reallocating a thread stack in a multi-threaded operating system, and more particularly, a method of dynamically allocating a thread stack of a multi-threaded operating system in an embedded system for wireless sensor nodes. The method includes the steps of: measuring sizes of data and non-data sections of a stack with respect to each thread; determining a new size of the non-data section of each stack based on the size of the data section of the stack measured with respect to each thread; and adjusting the size of the non-data section of each stack to the determined new size. According to the method, even without the source code analysis, an amount of memory spaces to be used can be reduced compared to that of a conventional static stack allocation method.

摘要： The present disclosure relates to a method for generating a synthetic image. In the method, image data is generated using a receiving dynamic beamforming method, image data is generated using a synthetic aperture beamforming method, and the image data generated using the receiving dynamic beamforming method and the image data generated using the synthetic aperture beamforming method are synthesized with being applied with weighting factors according to advancing distances of ultrasonic waves. By using a zone blending method, in which image data according to a receiving dynamic beamforming method is mainly used for an ultrasonic image having a predetermined depth or less, and image data according to a synthetic aperture beamforming method is mainly used for an ultrasonic image having any other depth, a grating lobe and distortion of image brightness are eliminated. In addition, the non-uniformity of the image is compensated, and a uniform energy density is acquired even in an area near a virtual transmission sound source.
