To investigate inter-/intra-observer variability in defining the prostate by use of planning computed tomography (PCT) and cone beam CT (CBCT) with magnetic resonance image (MRI) as guidance prior to introduction an adaptive radiotherapy for cancer.We reviewed PCT firstly acquired CBCT datasets each ten patients cancer. Three physicians independently delineated based on MRI guidance, allowing determination inter-physician variability. Two repeated contouring three times total intra-physician...
This paper presents a heterogeneous configuration of two different target quad-core CPUs. To support both high-performance and high energy-efficiency depending on application requirements, types CPUs are implemented in one mobile processor. The first type CPU is designed to give the highest performance at cost reasonable power consumption. second optimized with emphasis energy efficiency than performance. addresses design features for optimization issue low-power CPU. best shows 1.8X lowest...
This study introduces the Sleepcare Kit and S-Pillow (SKP), a wearable body-area network concept designed to address uncomfortable imprecise measurements associated with previous sleep apnea diagnosis treatment methods that depend on external servers or human experts. SKP measures respiration, acceleration, SpO2 signals accurately identify risky in real-time. In addition, it incorporates can deterministically adjust position of patient's head resolve symptoms. operates self-x based closed...
ABSTRACT The breathing motion moves internal organs and targeted regions determined by radiation therapy planning. For the therapy, accurate prediction for is of great interest as outer region treatment could endanger sensitive tissue. In this study, use a algorithm with adaptive support vector regression (aSVR) was proposed compared neural network (ANN) considering accuracy training predicting time. Respiration data from 87 patients treated were acquired an optical marker at 30 Hz. Five...
Purpose To evaluate respiratory motion of a patient by generating four-dimensional digital tomosynthesis (4D DTS), extracting signal from patients' on-board projection data, and ensuring the feasibility 4D DTS as localization tool for targets which have movement. Methods Materials Four patients with lung liver cancer were included to verify 4D-DTS an imager. CBCT acquisition (650–670 projections) was used reconstruct images breath generated diaphragm during data acquisition. Based on...
Our study examined the prognostic factors involved in outcome of patients with chronic subdural hematoma (CSDH) who had undergone burr hole drainage procedures, and investigated association between traumatic head injury. In addition, we explored related to recurrence.This enrolled 238 CSDH drainage. Patients history injury were categorized into trauma group compared no group. Outcome was considered good when modified Rankin Scale scores improved from admission discharge final follow-up.Among...
This study proposes a network failover protocol for public safety devices, such as fire alarms and gas leak detectors using cellular (i.e., 5G LTE) Internet of Things (IoT) network, evaluates its performance through experiments. The proposed recovers communication functions by establishing detour route the secondary 447-MHz narrowband wireless network) when problem occurs in primary disaster situation. All operations are performed autonomously self-organization collaboration distributed...
Abstract Recent research has focused on exploring systems that incorporate anomaly detection models to automate the addition of users in user recognition systems. Anomaly detection, a method used distinguish between new and existing by identifying abnormal images, gained significant attention. Researchers have been actively investigating Semi-Supervised Learning method, which utilizes only data differentiate users. However, semi-supervised learning based exhibit high performance datasets...
A home network is a typical ubiquitous computing that consists of various consumer devices and service environments. Home networks are requiring increasingly more complicated services, such as multimedia theater the monitoring controlling heterogeneous devices. Accordingly, mutually connecting mechanism needed among services redundant. The current paper presents Multimedia Room Bridge Adapter (MRBA) system designed to manage support services. In addition, hardware software prototype...
Background and Objectives Temporal bone is a complicated structure anatomically. Highresolution computed tomography (HRCT) provides good method for examination of the middle ear, inner ear anatomy pathologic changes in temporal bones. The purpose this study to evaluate relations facial nerve other structures factors influencing access posterior tympanotomy according age, sex degree pneumatizaton. Subjects Method A total 133 ears computer tomograph (TBCT) were analyzed. We measured distances...
In this study, the reduction of dose and risk was evaluated from using automatic mA control in 4D CT scan patients whose organ movement considered for gated radiotherapy. The doses, CTDI, effective doses with without were CT-Expo program each 10 liver lung cancer, exposure induced death loss life expectancy PCXMC program. It founded that there 26.8%, 15.5% CTDI cancer 16.5% 19.8% patients. parameter patient used scans, risks considering age gender could be evaluated. 21.2% 18.2% AEC
The purpose of this study is to improve the firing elevation driving method for towed howitzer prevent musculoskeletal disorders. To adjust elevation, it required rotate hand wheel and work has been done manually in test range as same field artillery troops. In range, motor-driven adjustment device was developed working efficiency safety. These were compared by using posture classification scheme RULA REBA. It measured elapsed time investigate improved operational efficiency. optimal upper...
In this paper, we introduce a ubiquitous voice message broadcast system - called u-Paging, by combining the technique of location-awareness and delivery service in sensor network environment. To actualize u-Paging service, specialized hardware middleware architecture are proposed under wire/wireless hybrid network.
