Introduction Patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. In this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4D) XCAT anthropomorphic phantom. Materials and Methods To access 4D modeling of motion...

Introduction: Motion of the patient during myocardial perfusion SPECT could potentially results in false perfusion defects. The effect of different reconstruction methods on these artifacts is not studied. Clarification of the relation between the extent, severity and duration of motion with the resultant artifacts may be helpful in designing special soft wares for motion correction. This...

Objective: Parkinson Disease (PD) is a progressive deficit of central nervous system. This disease can affect gait performance. The objective of this study was to assessment the range of motion and muscle activity of lower limbs in a PD patient and a normal elderly subject.   Methods: one patient with PD (height=173 cm, weight=63 kg, age 53 years) and one normal elderly subject (height=1...

Background: Postoperative physiotherapy is routinely prescribed for patients after thoracic surgeries. There are no established guidelines for exercise prescription after pleural resection surgeries. The present study aimed to determine the effect of an individualized postoperative physiotherapy program on a patient who underwent pleurectomy. Methods: A 19-year-old female patient was admitted ...

Introduction: In radiotherapy with external surrogates, exact information of tumor position is one of the key factors that improves treatment delivery. Many dynamic tumors in thorax region of patient move mainly due to respiration and are known as intra-fractional motion error that must be compensated, as well. One of clinical strategy is using Stereotactic Body Radiation Thera...
