Observations on detecting left ventricular thrombus with two dimensional echocardiography: emphasis on avoidance of false positive diagnoses Axial and lateral resolution problems inherent with this technique can produce intracavitary echoes that may simulate thrombi. In addition, normal or pathologic ...
Volumetric measurement of the lateral ventricle using high-resolution magnetic resonance imaging (MRI) by Allen et al.8 revealed site- and sex-related variations. In both males and females, the right lateral ventricle was significantly larger than the left. Range and mean were also generally greate...
frequency bandwidth, numerical aperture, depth to an object, and spatial sound pressure field, particularly focusing, dictate the maximum imaging quality capable by any setup2,3. In addition, ultrasonic systems do not maintain equal resolution along the axial and lateral directions...
超分辨(super-resolution)、超级反射镜(super-mirror) 超光谱(hyper-spectroscopy) 超现实主义(sur-realism) 您看,英文不同的前缀,中文一字译之:超。 Thorlabs Pound-Drever-Hall超稳激光装置 Transverse vs. Lateral 这两个词都有横向的意思,但从哪里横是一个问题。引用Thorlabs正弯月透镜应用的英文描述: ...
The appropriate way to prevent poor resolution is to use the smallest FOV that encompasses the region of interest40. When it comes to the radiation issues, there have been controversies about performing CBCT routinely for orthodontic patients, especially in young patients. As part of the routine ...
In the first technique, the dynamic impact loads, the nonlinear dynamic responses and failure behaviors of both bridge structure and impacting vessel such as the crush deformations are quantified considering detailed collision mechanics and nonlinear interactions between the high-resolution FE models of im...
and cylindrical cores. The DIC system consists of two light-weight CMOS cameras with a USB 3.0 interface for distances up to 25 m. The high sensitivity cameras have a resolution of 2.3 Megapixel at 100 Hz frame rate. These are connected to a controller which also acts as a data acquisitio...
The sources correspond to an area of loss of resolution of the Vp/Vs model because S-waves are strongly attenuated during their travel within the magma-filled volume. Full size image All the sources are located beneath the summit area in the 3–9 km depth interval, with a clear spatial...
The measurement uncertainty was obtained from the range of wingbeat motion and angular resolutions of the robotic model (360/4096°, XH430, Robotis), a spatial resolution in the command signal (updating interval of 5 ms, 1/1600T), and the resolution of the sensor of 3.13 × 10...
