Physiological changes in dynamic PET images can be quantitatively estimated by kinetic modeling technique. The process of PET quantification usually requires an input function in the form of a plasma-time activity curve (PTAC), which is generally obtained by invasive arterial blood sampling. However, invasive arterial blood sampling poses many challenges(More)
To investigate the selective pressures acting on the protein-coding genes during the differentiation of indica and japonica, all of the possible orthologous genes between the Nipponbare and 93-11 genomes were identified and compared with each other. Among these genes, 8,530 pairs had identical sequences, and 27,384 pairs shared more than 90% sequence(More)
The gradual decreasing capacity of lithium-ion batteries can serve as a health indicator for tracking the degradation of lithium-ion batteries. It is important to predict the capacity of a lithium-ion battery for future cycles to assess its health condition and remaining useful life (RUL). In this paper, a novel method is developed using unscented Kalman(More)
The objective and quantitative analysis of longitudinal single photon emission computed tomography (SPECT) images are significant for the treatment monitoring of brain disorders. Therefore, a computer aided analysis (CAA) method is introduced to extract a change-rate map (CRM) as a parametric image for quantifying the changes of regional cerebral blood flow(More)
Rehabilitation, which is essential for amputees with myoelectric hands, can improve the quality of daily life by remodeling the neuron network. In our study, we aim to develop a cerebral blood perfusion (CBF) single-photon emission computed tomography computer-aided (SPECT-CA) detection scheme to automatically locate the brain’s activated regions after(More)
BACKGROUND [18F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) has been widely used in oncologic procedures such as tumor diagnosis and staging. However, false-positive rates have been high, unacceptable and mainly caused by inflammatory lesions. Misinterpretations take place especially when non-subcutaneous inflammations appear at the(More)
"Wayfinding system" is an interdisciplinary research between the environment design and human interface of information system. The design of EXIT is to efficiently help people to identify the emergency exit when the accident occurred. In this paper, eye tracking techniques are utilized to aided EXIT design in the wayfinding system. The mobile eye tracking(More)
Micro-PET/CT has been widely used for brain imaging in diverse preclinical studies using mouse models. The precise brain extraction is an important pre-procedure to quantify the brain function based on micro-PET/CT images. In this study, we explored an automatic framework based on a modified level-set method (MLS) for mouse brain extraction in micro-PET/CT(More)
The fluorodeoxyglucose positron emission tomography (FDG-PET) has demonstrated advantages in the assessment of tumor response to therapy. The high-quality quantitative assessment usually relied on the accurate lesion detection. Hence, we aim to develop an objective method to automatically detect lesions for measuring tumor response to therapy using dynamic(More)
