Introduction: Siliconeprosthetic implants are commonlyutilizedfor tissue replacement and breast augmentation after mastectomy. On the other hand, some patients require adjuvant radiotherapy in order to preventlocal-regional recurrence and increment ofthe overall survival. In case of recurrence, the radiation oncologist might have to irradiate the prosthesis.The aim of this study was to evaluate...

BACKGROUND AND PURPOSE An analysis of the current radiotherapy status in Turkey was conducted to establish a comprehensive baseline. Turkey's future demand analysis in view of international benchmarks was conducted. Moreover, the ministerial plans are shared to present an example for making a comprehensive planning in developing countries. METHODS The data from all radiotherapy centers in Tur...

The use of image-guidance in surgery and radiotherapy has significantly improved patient outcome in neurosurgery and radiotherapy treatments. This work developed volume definition and verification techniques for image-guided applications, using a number of algorithms ranging from image processing to visualization. Stereoscopic visualization, volumetric tumor model overlaid on an ultrasound imag...

Accurate image registration for CT-CT, CT-MRI for brain is necessary to obtain clinical information from diagnostic images and translate the information to radiotherapy treatment planning CT images. Mostly in cases of Post-Surgery cases that have been operated outside hospitals and are being referred for Post-Operative adjuvant Radiotherapy to our Centre, where the pre-operative volume is very ...

CONTEXT Postoperative periampullary cancers with high risk features are managed with adjuvant chemo radiotherapy. Doses of 40-50 Gy have generally been used in conventional radiotherapy. Dose escalation with conventional radiotherapy has been restricted due to surrounding critical organs. OBJECTIVE The objective of this dosimetric analysis was to evaluate the dose of radiation received by org...

Effective treatment for carcinoma of the lung remains one of the biggest challenges in oncology. Radical radiotherapy may be a curative option for patients who are unsuitable for radical surgery either because of disease stage or because of co-morbidity. Long-term disease control with radical radiotherapy is disappointing with only about 6% of patients treated being alive at 5 years. Technologi...
