XIn this paper, we use an FPGA platform and a high level synthesis tool, called Impulse C, to speedup a statistical Line Of Reaction (LOR) estimation for a high-resolution Positron Emission Tomography (PET) scanner. The estimation algorithm provides a significant improvement over conventional methods, but the execution time is too long to be practical for(More)
BACKGROUND Treatment options for nonunion of the femoral shaft fracture after intramedullary nail fixation are controversial. The methods of exchanging an existing nail with a larger-sized nail, dynamization, removal of the nail followed by plating, and bone grafting have all been reported. From those options, exchange nailing seems to be the most popular(More)
Epileptogenesis, which occurs in an epileptic brain, is an important focus for epilepsy. The spectral analysis has been popularly applied to study the electrophysiological activities. However, the resolution is dominated by the window function of the algorithm used and the sample size. In this report, a temporal waveform analysis method is proposed to(More)
OBJECTIVE Reconstruction for osteosarcoma around the knee after wide resection faces the challenge of great bone defect and future limb length discrepancy in the skeletally immature patients. Modern prosthetic reconstruction may provide good results, but the longevity may be of concern and may not be affordable in certain communities. Allograft knee(More)
Bone and joint pain are commonly encountered conditions in daily practice. In the elderly, when osteolytic lesions are identified in imaging studies, metastatic bone tumor is the first impression that comes to the clinician's mind. Although the worst-case scenario should be ruled in, other differential diagnoses such as metabolic bone disease should be(More)
SUMMARY Set Partitioning in Hierarchical Trees (SPIHT) is a highly efficient technique for compressing Discrete Wavelet Transform (DWT) decomposed images. Though its compression efficiency is a little less famous than Embedded Block Coding with Optimized Truncation (EBCOT) adopted by JPEG2000, SPIHT has a straight forward coding procedure and requires no(More)
A physical modeling method for electronic music synthesis of plucked-string tones by using recurrent networks is proposed. A scattering recurrent network (SRN) which is used to analyze string dynamics is built based on the physics of acoustic strings. The measured vibration of a plucked string is employed as the training data for the supervised learning of(More)
