Time-of-flight (TOF) PET has the potential to improve the SNR. In order for TOF information to reduce the statistical noise and boost the performance of respiratory gating, we present a robust data-driven respiratory gating method using TOF information, which retrospectively derived the respiratory signal from the acquired TOF-PET data. The PET data was acquired in list mode format and analyzed in sinogram space. The method was demonstrated with patient datasets acquired on a TOF PET/CT system. Data-driven gating methods by center of mass (COM) and principle component analysis (PCA) algorithm were successfully performed on nonTOF PET and TOF PET dataset. To assess the accuracy of the data-driven respiratory signal, a hardware-based signal was acquired for comparison. The study showed that retrospectively respiratory gating using TOF sinograms has improved the SNR, and outperforms the non-TOF gating under both COM and PCA algorithms.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...

However, conventional physical checks are discrete and transient, which is incapable for the health monitor of daily living. Dedicated to everyday physiological monitor, we have developed a multi-parameter smart armband which is able record pulse, temperature and triaxial accelerations continuously. With the wearable device and signal processing algorithm, experiments of data acquisition in the daily living have been implemented on the volunteers. The long period record of 38 hours has demonstrated its feasibility of a total record without disturbing. And both historical and cross comparisons on the parameter correlation analysis have proven the valuable health information that the armband could reveal. As an integrated sensor module, the smart armband is simple and non-obtrusive, thus opens a promising approach towards the pervasive health monitor, especially for the elder population.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...

Seventy human hip cartilage-bone samples were collected from hip-fracture patients (ages 51 to 96) and divided into 5 groups (10 years in an age group). They were firstly measured by ultrasound to obtain quantitative acoustic parameters, including the speed of sound (SOS), US amplitude attenuation coefficient (UAA) and normalized broadband US attenuation coefficient (nBUA). Then the samples were stained for GAG with toluidine blue. Results showed SOS, UAA, nBUA decreased by 5.49%, 36.67%, 25.57% from 50-80 age group (p<;0.01), but increased by 0.34%, 1.19%, 5.23% in the 90 age group compared with the 80 age group, respectively. There were linear correlations between SOS and GAG optical density (r=0.825, p<;0.01), as well as UAA and GAG optical density (r=0.708, p <; 0.01). However, nBUA showed less significant linear correlation to GAG optical density (r=0.688, p <; 0.07). In summary, GAG content of hip joint cartilage varied with aging in elderly people and conventional ultrasound can potentially be used to detect the age-related changes of acoustic parameters of human hip joint cartilage.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...

METHODS SD rats with spinal cord injury induced by Allen method was divided into two groups, experimental group rats received active stimulator units and control group rats received sham (inoperative) stimulator units. The electric field intensity was 600μV/mm, and the polarity alternated every 15 min. RESULTS The results showed that the experimental group rats had significantly better locomotor function recovery (inclined-plane testing and modified Tarlov motor grading scale) 5 weeks after the injury (P<;0.05). OFS treatment significantly decreased motor evoked potential (MEP) latency differences and amplitude differences 4 w and 8 w post injury (P<;0.05, P<;0.01). Furthermore, the number of axons was quantified by immunofluorescence staining of nerve fiber (NF), increased axon numbers were observed at 4 w and 8 w in experimental group (P<;0.05). CONCLUSIONS These findings suggest OFS can promote motor function recovery in SCI rats, and this effect may be related to the improving axon regeneration in spinal cord.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...
