摘要： The invention relates to an intraluminal stent (80) comprising a tubular main body portion which is sized for intraluminal placement within a body passage. The main body portion is formed at least in part from a material which has been rolled into a substantially cylindrical configuration. The main body portion includes a plurality of tine receiving cavities (84) and a plurality of tine elements (86), said tine elements (86) being slidable in respective tine receiving cavities (84) whereby sliding movement of said tine elements (86) in said first direction in said tine receiving cavities (84) selectively increases or decreases a diameter of said main body portion.

摘要： A system delivers a number of safe doses from a pressurized and metered medication canister (13) via a dispenser (10) to a patient. The improvement includes a counter device (130) for accurately determining the number of safe doses delivered from the medication canister. Also a warning device (131) alerts the patient either visually, audibly, mechanically or in a combination thereof about an impending and then a final exhaustion of the number of safe doses delivered from the medication canister. The improved system takes advantage of the patient-actuated movement of the medication canister in the dispenser body to activate either an electronic or a mechanical counter device. Alternatively, the improved system may be patient-activated independently from, but in conjunction with, the dispensing of medication from the canister.
摘要翻译：系统通过分配器（10）向患者提供来自加压和计量的药物罐（13）的许多安全剂量。该改进包括用于准确地确定从药物罐递送的安全剂量的计数器装置（130）。警告装置（131）也可视觉地，听觉地，机械地或以其组合的方式警告患者关于药物罐递送的安全剂量的即将到然的最终耗尽。改进的系统利用患者在分配器主体中的药剂盒的运动来激活电子或机械计数器装置。替代地，改进的系统可以独立于药筒从罐分配，但是与患者的活化无关。

摘要： One or more systems, methods, or computer program products can include receiving an echo data set including information representative of an echo sensed by a transducer, provided at least in part by one or more actual targets included in a region of interest. The region of interest can be modeled, including selecting or generating an array manifold matrix including information corresponding to any one or more candidate targets. The weights of the candidate targets can be determined using the array manifold matrix and the echo data set, including minimizing an argument of a function modeling the weights of the candidate targets. In an example, the echo data set can be dithered, such as by adding a specified dithering signal.

摘要： In some illustrative embodiments, an incoming signal from a transducer (110) in an ultrasound imaging beam-former apparatus (100) is applied to an in-phase sample-and-hold (120) and a quadrature sample-and-hold (130). The quadrature sample-and-hold (130) may be clocked a quarter period behind the in-phase sample-and-hold (120). The output of the sample-and-holds are applied to in-phase and quadrature analog-to-digital converters (126). A magnitude calculator (138) receives the in-phase and quadrature digital values, and outputs a magnitude. A phase calculator (142) receives the in-phase and quadrature digital values, and outputs a phase. An apodizer (146) applies a difference between an amplitude of the outgoing signal and the magnitude and applies a first illumination (150-1) to a image point (154) in substantial proportion to the difference, and a phase rotator (152) applies a second illumination (150-2) to the image point (154) in substantial proportion to the phase.

摘要： An ultrasound system and related method for forming 2D C-scan images and/or collecting 3D image data from 2D transducer arrays. The system including in part a 2D transducer array of elements, transmit voltage generation means for each element, a memory buffer with or part of channels for each element, and a receive beamformer. On a time serial or sequential basis, several times for each line of firing, the contents of the per element memory buffer are read into the beamformer with different focusing values for each buffer reading cycle. In this way, the beamformer can calculate beamformed image values for multiple points per line firing cycle-or per each line of signals between the transducer array and receive beamformer.

摘要： A hand held ultrasonic instrument (10) is provided in a portable unit that performs C-Mode imaging and collects 3D image data. In a preferred embodiment a transducer array (60), display unit (20), beamformer (40), power system, and image processor are integrated in one enclosure weighing less than three pounds. In operation, the portable unit is scanned across a target and the displayed image is conveniently presented to the operator whereby the displayed image corresponds exactly to the target, or a scaled fashion if desired.
