We show that every uniformly asymptotically affine circle endomorphism has a uniformly asymptotically conformal (UAC) extension to the complex plane. Then we use the UAC extension to construct the dual dynamical system, the dual annulus, and the dual circle expanding map.

Background: The aim of this study was to develop and implement a Monte Carlo framework for evaluation of patient specific out-of-field organ equivalent dose (OED). Materials and Methods: Dose calculations were performed using a Monte Carlo-based model of Oncor linac and tomographic phantoms. Monte Carlo simulations were performed using EGSnrc user codes. Dose measurements were performed using r...

PURPOSE To investigate the immediate and long term therapeutic effects of radiofrequency hyperthermia combined with conformal radiotherapy in patients with hepatocellular carcinoma (HCC). METHODS Data was collected from 80 patients with HCC. All of the patients had confirmed primary HCC according to their clinical symptoms, imaging examinations, biochemical examinations and pathology. Patient...

Aim: To prospectively evaluate the acute toxicity of 3D conformal radiotherapy with dose optimization in patients with carcinoma cervix. Materials and Methods: Carcinoma cervix patients stage IIB to IIIB (n = 30) treated during November 2011 to May 2013 at the institution with 3D conformal chemo-radiation were included in the study. They received weekly Cisplatin 40 mg/m2 for a maximum of 5 cyc...

OBJECTIVE To investigate the pattern of care and outcomes for newly diagnosed glioblastoma in Italy and compare our results with the previous Italian Patterns of Care study to determine whether significant changes occurred in clinical practice during the past 10 years. METHODS Clinical, pathological, therapeutic, and survival data regarding 1059 patients treated in 18 radiotherapy centers bet...

Due to acute and particularly chronic postirradiation complications in radiotherapy of the prostate, the dose application, and consequently also the irradiation effect, are restricted. The incidence and grade of acute and chronic complications depend upon the dose and volume of the surrounding organs involved in the irradiation area.1-4 As the restrictions on dose application should in no way b...

BACKGROUND The aim of the retrospective study was to evaluate the outcome and prognostic factors of newly diagnosed glioblastoma patients who received 3-D conformal radiotherapy (RT) combined with concomitant and/or adjuvant temozalamide (TMZ) postoperatively. PATIENTS AND METHODS Fifty patients with glioblastoma multiforme were treated with 3-D conformal RT combined with concomitant and/or a...

Introduction: The rate of cardiac diseases have increased among patients who underwent radiotherapy for left-sided breast cancer. The study’s aim was evaluate the dose to organs at risk in free-breathing 3-dimensional conformal (FB-3DCRT) against 3-dimensional conformal deep inspiration breath-hold (3DCRT-DIBH) in patients with left-sided breast cancer. Ma...

BACKGROUND Increasing the radiotherapy dose can result in improved local control for non-small-cell lung cancer (NSCLC) and can thereby improve survival. Accelerated hypofractionated radiotherapy can expose tumors to a high dose of radiation in a short period of time, but the optimal treatment regimen remains unclear. The purpose of this study was to evaluate the feasibility of utilizing high-d...
