摘要： A method and apparatus for improving the penetration of the harmonic imaging while preserving the image uniformity by using signals from a similar frequency band to form a composite image. A near field image uses primarily tissue generated harmonic signal associated with a first transmitting event that has a center frequency of f1. Such tissue generated harmonic signal has a frequency band centered on 2f1. In the far field, fundamental echo signals from the second transmitting event that has a center frequency of f2 are primarily use. Since the center frequency f2 in the transmitting event is close to 2f1 and there is a significant overlap in frequency band between signals extracted from the first transmitting event and signals extracted from the second transmitting event, a composite image formed from these signals has similar speckle size across the whole image. The extracted signal from the second transmitting event is a fundamental component of the received echo and such signal has much larger amplitude than the tissue generated harmonic signal from the first transmitting event. Adding the fundamental signal from the second transmitting event in the far field improves the penetration of the harmonic imaging without sacrificing image uniformity.
摘要翻译：一种用于通过使用来自相似频带的信号来保持图像均匀性来改善谐波成像的穿透以形成合成图像的方法和装置。近场图像主要使用与具有f1的中心频率的第一发射事件相关联的组织产生的谐波信号。这种组织产生的谐波信号具有以2f1为中心的频带。在远场中，主要使用来自具有f2的中心频率的第二传送事件的基本回波信号。由于发送事件中的中心频率f2接近2f1，并且在从第一发送事件提取的信号和从第二发送事件提取的信号之间的频带中存在显着重叠，所以从这些信号形成的合成图像具有相似的散斑大小跨越整个形象。来自第二发送事件的提取信号是接收到的回波的基本分量，并且这样的信号具有比来自第一发送事件的组织产生的谐波信号大得多的振幅。从远场中的第二发送事件添加基本信号可以改善谐波成像的穿透，而不会牺牲图像均匀性。

摘要： A method and apparatus for smoothing speckle pattern and increasing contrast resolution in ultrasound images is provided. Compared to other frequency compounding techniques, wide-band harmonic frequency compounding reduces speckle noise without sacrificing the resolution. Compared to spatial compounding, wide-band harmonic frequency compounding is more robust against tissue motion because sequential vectors rather than frames are summed together for compounding. The method and apparatus is implemented by transmitting two or more firings, combining two or more of the firings coherently to extract the tissue-generated harmonic components, detecting the outputs of the coherent sums and detecting one or more firings before coherent sum, and finally combining all detected outputs to form the compounded image. The method and apparatus sums wide-band fundamental and wide-band harmonic images after detection to form a compounded image. Unlike other frequency compounding methods, both transmit and receive signals are wide-band and no narrow-band filters are necessary. Multiple firings with two or more different transmit waveforms are transmitted to each focal zone.

摘要： Presented is a method of operating a capacitive microfabricated ultrasonic transducer (cMUT) array with multiple firings of varying bias voltage polarity patterns to improve its performance in imaging non-linear media, such as in contrast agent imaging or tissue harmonic imaging. Additionally, transducers incorporating the method are provided. The method of cMUT operation and the corresponding cMUT does not require pre-distortion or phase inversion of the transmit signal and can achieve an improvement in the elevation focus of the cMUT, as compared to the elevation focus that a single firing can achieve. Further, the method of operating the cMUT minimizes the deleterious effects that result from insulators being subjected to high electric fields.

摘要： A capacitive microfabricated ultrasonic transducer (cMUT) is operated to improve its performance during harmonic imaging in non-linear media, such as in contrast agents or in human tissue. The cMUT is operated by inverting the transmit waveform to adjacently spaced azimuth elements, and combining at least two additional firings without adjacent inversion, for each transmit vector, thereby canceling the second harmonic generation of the cMUT; and thus, the performance of harmonic imaging using the cMUTs can achieve improvement.

摘要： A transducer connects with a support arm. The support arm supports only some of the weight, even in a locked state. By only supporting a portion or less than all of the weight, the support arm allows downward movement or pressure, but less than the pressure applied without any resistance for the gravity acting on the support arm. The pressure maintains contact between the patient and the transducer for scanning.

摘要： A capacitive microfabricated transducer array used for 3-D imaging, with a relatively large elevation dimension and a bias control of the elevation aperture in space and time, confers the same benefits of mechanical translation, except that image cross-sections are electronically rather than mechanically scanned, and are registered very accurately in space. The 3-D cMUT, when combined with elevation bias control and convex curvature in elevation, increases the volume interrogated by the electronic scanning, thus improving field of view. Further still, the 3-D cMUT can be combined Fresnel focusing of the elevation section to improve the elevation focus.
