Gamma radiation has destructive effects on persons who are exposed to it and can cause damage healthy tissues. Therefore, shielding materials necessary for protecting against it. For this purpose, the attenuation characteristics of S-type glass – namely, soda–lime–silica (SLS) which was doped with antimony (III) oxide (Sb 2 O 3 ) were obtained by using MCNPX code, results compared XCOM software findings. The parameters four types SLS (no addition oxide), SLSS1 (0.005% SLSS2 (0.05% oxide)...
The study evaluates the different treatment planning techniques according to three recommendation levels of International Commission on Radiation Units and Measurements Report-83 in gynecologic cancer patients treated with adjuvant pelvic radiotherapy (APR).Computerized tomography images ten endometrial cervical who were APR assessed. For each patient, five plans created. One homogeneity index four conformity indexes (CIs) calculated for three-dimensional conformal (3D-CRT), field-in-field...
In this study, it is aimed to compare three different radiotherapy treatment planning techniques in terms of critical organ scoring index (COSI), two conformity (CI), tumor control probability (TCP), and normal tissue complication (NTCP) calculations early (T1) glottic larynx carcinoma (T1GL). Furthermore, investigate these parameters compliance with dose-volume histograms (DVH) parameters.Ten T1GL patients were immobilized a supine position head neck thermoplastic mask. Treatment plans...
Chemoradiotherapy is an important treatment modality for lung cancers. The aim of this study was to investigate alterations in, as well the interrelationship between, function and quality life patients receiving chemoradiotherapy due locally advanced non-small cell cancer (NSCLC) small (SCLC) limited thorax.The included definitive carcinoma. respiratory assessed by measuring forced expiratory volume in 1 s per unit (FEV1) 1s vital capacity (FEV1/VC) before, middle after treatment. During...
e17526 Background: Approximately one third of patients with NSCLC has locally advanced disease that is surgically unresectable. Current treatment in these cases concurrent chemoradiotherapy (CRT). Recently, heparin and also LWMH have been shown inhibit tumor growth incriase the efficacy chemotherapy. In this study, we decided to assess CRT a unresectable NSCLC. Methods: Between February 2003 May 2009, or medical inoperable our oncology clinic were evaluated as retrospective. The are divided...
Bilgisayarlı tomografi (CT) günümüzde etkin bir şekilde kullanılan modern cihaz olup, tanısal görüntülemede çok önemli yer tutmaktadır. Bu çalışmanın amacı, CT’de tüp voltajı (kVp), akımı (mAs) ve kesit kalınlığı değerlerini değiştirerek farklı çaplara sahip biri 16 cm çapında diğeri 32 olan su eşdeğeri silindirik iki adet fantomda doz değişimlerini incelemektir. İyonizasyon odası ile okunan soğurulan değerleri bilgisayarda var paket programı yardımıyla ilgili parametrelere çevrilmiştir....
The main aim in radiotherapy is maximizing radiation dose into cancer cell and protecting health tissue around this cancer. Nowadays, with the development of technology treatment tumor becomes possible by small field size. This new technique, so called IMRT (Intensity Modulated Radiation Therapy) requires dosimetric confirmation. One most important things to be controlled planned fields treated which it’s especially, size using multi field. other point values according calculated time unit...
Purpose The purpose of this study was to evaluate the tumor control probability (TCP), normal tissue complication (NTCP) and adaptive time management (ATM) in patients who had non-small cell lung cancer (NSCLC) underwent radiotherapy with same gap length at different treatment weeks.Material Methods Twenty patients' definitive treatments, completed 6.5 weeks, were evaluated retrospectively. Three scenarios gaps 5 fractions weeks (2nd, 4th, 6th week) planned. ATM models (biologically...
Abstract Background/aim: Radiation dosimetry requires special phantoms which are comparable with organs and tissues of a human body. The lung is one the low density. Therefore, it important to create use equivalent in dosimetric controls. aim this study was investigate importance using for different respiratory phases during measurements both computed tomography (CT) linear accelerator. Materials methods: maximum inhalation phantom (LIP) exhalation (LEP) were created two phases. Hounsfield...
Modern lineer hızlandırıcı (Linak), kanserli hastaların tedavisi için yüksek enerjili X ışınları ve elektron demetleri üreten bir cihazdır. Radyasyon tedavisinin temeli madde radyasyon arasındaki etkileşime dayanır. Bu nedenle, etkileşim, fiziği bilimini kanserin klinik tedavisine dönüştürür. Radyoterapide, dozimetrik ölçümler en temel rölatif değerlendirmeler; X- ışınının derinliğe bağlı olarak değişimi gösteren yüzde derin doz (%DD) belli derinlikte ışının düzgünlüğünü simetrisini ışın...
In Patient Quality Assurance measurements for Intensity Modulated Radiation Therapy, this study aimed to investigate the dosimetric differences between calculated and measured values when standard equipment contains different density materials. METHODSIn study, a setup that can be used both absolute dose planar distribution is considered effects of selected grid size value in treatment planning system on Monitor Unit, 2D array gamma evaluation absorbed measurements.Also, using "distance...
AMAÇ: Çalışmada, pelvik radyoterapi ve prostata eşzamanlı ek doz (SIB) uygulanmış prostat kanserli hastalarda, konformal (3BKRT) çalışması temel alınarak, 3 farklı Yoğunluk Ayarlı Radyasyon Tedavisi (IMRT) tedavi tekniğine ait iki Uygunluk indeksi (CI), Kritik Organ Skorlama İndeksi (COSI), Tümör Kontrol Olasılığı (TCP) Normal Dolu Komplikasyon (NTCP) hesaplamaları ile Doz Volüm Histogramları (DVH) parametrelerinin karşılaştırılması amaçlanmıştır.GEREÇ VE YÖNTEM: Kliniğimizde görmüş 5 hasta...
Abstract Metal Artefact Reduction (MAR) is very important in terms of dose calculation radiotherapy. It was aimed to develop an in-house MAR software as alternative commercial programs and examine its effectiveness by comparing it with the SMART-MAR which available commercially. A phantom containing metal high atomic number designed computed tomography (CT) images this were taken (Without-MAR images). The obtained CT processed developed In-House software. Processed compared Hounsfield unit...
