Cone Beam Computed Tomography (CBCT) is an imaging modality that has been used in image-guided radiation therapy (IGRT). For applications such as lung radiation therapy, CBCT images are greatly affected by the motion artefacts. This is mainly due to low temporal resolution of CBCT. Recently, a dual modality of Electrical Impedance Tomography (EIT) and CBCT has been proposed, in which the high t...
OBJECTIVES Assessment of physiologic renal motion in order to optimize abdominal intensity-modulated radiation therapy and stereotactic body radiation therapy. METHODS AND MATERIALS Twenty patients with a median age of 47 years underwent computed tomography simulation and four-dimensional computed tomography acquisition. Thirty-nine kidneys were contoured during ten phases of respiration to e...
Abstract With the booming development of smart wearable devices, flexible multifunctional composites with high sensitivity and well health therapy have evoked great interest for next-generation healthcare electronics. However, weak biocompatibility, low breathability, narrow sensing range greatly hinder sensors. Herein, a porous, conductive MXene/Polydimethylsiloxane/Polydopamine/Polyurethane S...
امروزه تخمین حرکت بلوک در تصاویر بر اساس روش هایی که تمام جزئیات را شامل می شوند، تبدیل به یک مبحث فراگیر در شاخه ی پردازش تصویر گشته است. چرا که از جمله ی روش هایی به حساب می آید که باعث فشردگی و کاهش حجم داده های تصویری می گردد. جهت تحقّق این هدف، الگوریتم های متفاوتی ارائه شده اند. الگوریتم های جستجوی محلی، جستجوی پیشگویانه و... که با توجه به نیاز مسأله انتخاب و مورد استفاده قرار می گیرند، از...
stability and performance are two main issues in motion of bipeds. to ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. however, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. step length and step perio...
Sampling-based path planning algorithms are powerful tools for computing disassembly motions. This paper presents a variant of the RRT algorithm particularly devised for the disassembly of objects with articulated parts. Configuration parameters generally play two different roles in this type of problems: some of them are essential for the disassembly task, while others only need to move if the...
In recent years, particle therapy has become a widely accepted form of cancer treatment and technological advances in beam delivery technology (i.e. pencil beam scanning (PBS)) have enabled the application of highly conformal dose distributions to static targets. Current research focuses on the possibilities for the treatment of mobile targets with these techniques. Of different motion mitigati...
In this paper, we propose a shadow play animation system that utilizes motion planning algorithms to generate Chinese shadow play animation automatically according to user’s highlevel inputs. The motion of a character in a shadow play show usually consists of intended primary motion and reactive secondary motion. We propose to use the RRT-Connect algorithm to generate primary motions and design...
روشهای متعددی مانند روش التراسونیک، روش مغناطیسی، روش راداری، روش مادون قرمزی و لیزری، روش دنباله ویدیویی، استفاده از سیستم موقعیت یاب جهانی و ... برای تعیین سرعت موجود است. در سالهای اخیر روش نوینی برای تعیین سرعت بر اساس یک تصویر گرفته شده به وسیله دوربین ساکن عنوان شده است. در این روش با استفاده از پارامترهای ماتی (تار شدگی) که شامل طول ماتی و جهت ماتی می باشد، سرعت جسم تخمین زده می شود. به ...
Background and Aim: Stroke is one of major causes of disability. Therefore, it is important to introduce and develop new treatment approaches in order to improve and enhance post-stroke recovery process for medical, social, and economical purposes. The present study aimed at determining the effect of mirror therapy on walking ability of patients with stroke regarding the muscular power of the a...
