introduction: the use of multiple cameras for motion analysis and single joint motion is very difficult and needs high technology in laboratory conditions. detection of single joint motion in kinesthesia and analysis of its changes can be done by one camera at one direction. in this study, we present the validity and reliability of a new prototype simulator system used for motion analysis appli...

Background: In intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. This study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

BACKGROUND The objective of this study was to evaluate a novel prostate endorectal immobilization system (EIS) for improving the delivery of hypofractionated Stereotactic Ablative Body Radiotherapy (SABR) for prostate cancer. METHODS Twenty patients (n = 20) with low- or intermediate-risk prostate cancer (T1-T2b, Gleason Score < 7, PSA ≤ 20 ng/mL), were treated with an EIS in place using Volu...

methods study on 34 patients diagnosed with rectal adenocarcinoma referred to oncology clinic was conducted. the treatment plan included 4050 cgy radiotherapy and 5fu, xeloda chemotherapy. all patients were assessed with 1/5 t mri 6 to 8 weeks after treatment. t1 and t2 images with sagittal, cronal and axial planes with and without contrast agent were obtained and interpreted by two radiologist...

The surgical approach for treating patients with rectal cancer has evolved from the perineal resection to sphincter-saving surgery so as to decrease local recurrence and to preserve organs. Along with surgical advances such as the total mesorectal excision (TME), the introduction of chemoradiotherapy (CRT) has significantly lowered the local recurrence rate from 15%–20% to 4%–5% [1]. However, t...
