The finding that midget ganglion cells synapse exclusively with the midget bipolar cells, and that both are common near the fovea, provides the anatomical basis for the observation of small receptive fields and high visual acuity in this region. There are five types of diffuse ganglion cell, clas...
We also present an experimental evaluation that shows the obtained gains in accuracy for segmenting a variety of medical images, including MR images of the foot, CT thoracic studies of the liver, and MR images of the breast. 展开 关键词: fuzzy connectedness geodesic star convexity image forest...
We propose a novel symmetry-based technique for scalable lossless compression of 3D medical image data. The proposed method employs the 2D integer wavelet transform to decorrelate the data and an intraband prediction method to reduce the energy of the sub-bands by exploiting the anatomical symmetries...
The sonication elicited transient tactile sensations on the hand area contralateral to the sonicated hemisphere, with anatomical specificity of up to a finger, while EEG recordings revealed the elicitation of sonication-specific evoked potentials. Retrospective numerical simulation of the acoustic propagation...
Another example is to match an image of one subject to some predefined coordinate system, such as an anatomical atlas [1]. There has not been an effective approach to generate ground-truth flows for medical images. Widely used super- vised methods require ac...
MRI is the gold standard for spinal cord imaging; however, it still has disadvantages, including high cost, slow acquisition time, large foot print, lack of portability, and operating room (OR) incompatibility [[14], [15], [16]]. For these reasons, the use of MRI to guide stem cell ...
(larger tissue) scan at about 2 minutes per slide. On average, we can scan 6 sets of slides in 8-10 minutes. The process for loading and scanning the slides is extremely intuitive and training my staff has been quite easy. In terms of interpreting cases, using the MorphoLens 6 scanned...
To dramatically reduce the computation times, this issue can be tackled by replacing the forward operator with faster approximate models without compromising reconstruction quality [22]. However, this method only addresses the high demanding computational cost. The limitation of the memory footprint ...
this effectively tilts the CT images 202 and 206 by the same amount relative to the physical position of the patient 231. Towards the foot of the patient, any ultrasound scans overlaid onto the CT will be several centimeters lower (posterior direction) than the corresponding CT image. The opp...
x-ray radiation. The emission spectrum is decisively influenced by the x-ray tube voltage or the acceleration voltage with which the x-ray source is operated. In general terms, the higher the acceleration voltage is, the greater the average x-ray quanta energy of the emission spectrum also ...
