Image-guided tumor ablation for lung malignancies has emerged as a treatment modality for medically inoperable patients. Overall, image-guided lung tumor ablation is a minimally invasive procedure that has an acceptable safety profile and less impact on lung function. This is important for patients with poor pulmonary and/or cardiac functions or with multiple comorbidities, which prevent them f...

Targeted radiation therapy (RT) is a central component of cancer treatment in both the radical and palliative settings. A central and compelling feature of RT is its capacity to deliver a therapeutic effect for cancerous targets that lie deep within the body. Full exploitation of this effect has been limited by the clinical uncertainties in identifying the geometric boundaries of the target and...

At the very start of their clinical training, radiation oncologists tend to embrace technology. The specialty draws a preponderance of technophiles to it, and those few who are not at first passionate about technology quickly become so. This has been especially true over the past 2 decades with the introduction of innovative therapies such as three-dimensional conformal radiation therapy (3DCRT...

The Intensity Modulated Radiation Therapy (IMRT) together with Image Guided Radiation Therapy (IGRT) improves radiation therapy for head and neck cancer. On the one hand tumors can be better covered with radiation dose and on the other hand normal tissue can be better preserved. Carefully applied this leads to the same tumor control rate with reduced toxicity compared with conventional radiatio...
