Simultaneous Multiple Liver Metastasis Treated with Pencil Beam Proton Stereotactic Body Radiotherapy (SBRT) [PDF]

International Journal of Particle Therapy, 2021
Compared with photon stereotactic body radiotherapy (SBRT) plans that may have to use many more penetrating x-ray beams for each isocenter, proton SBRT with ultrahypofractionated doses use fewer beam angles and offer significantly reduced low-dose ...

Biologically Effective Dose and Rectal Bleeding in Definitive Proton Therapy for Prostate Cancer [PDF]

International Journal of Particle Therapy, 2021
Purpose and Objectives: With increasing use of hypofractionation and extreme hypofractionation for prostate cancer, rectal dose-volume histogram (DVH) parameters that apply across dose fractionations may be helpful for treatment planning in clinical ...

Decision making in the management of metastatic spinal tumors

Indian Spine Journal, 2022
The advent of newer systemic therapies has resulted in improved survival of cancer patients. Increased life expectancy necessitates strategies not only for palliation to improve quality of life but also for lasting local control of the spinal metastasis.

SEOR SBRT-SG survey on SRS/SBRT dose prescription criteria in Spain

Clinical and Translational Oncology, 2021
Stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS) are essential tools in radiation oncology. In Spain, the use of these techniques continues to grow as older linear accelerators (linacs) are replaced with modern equipment. However, little is known about inter-centre variability in prescription and dose heterogeneity limits ...

CVNN-based Channel Estimation and Equalization in OFDM Systems Without Cyclic Prefix [PDF]

XLI Simp\'osio Brasileiro de Telecomunica\c{c}\~oes e Processamento de Sinais (SBrT 2023), 2023
In modern communication systems operating with Orthogonal Frequency-Division Multiplexing (OFDM), channel estimation requires minimal complexity with one-tap equalizers. However, this depends on cyclic prefixes, which must be sufficiently large to cover the channel impulse response.

Simulated dose painting of hypoxic sub-volumes in pancreatic cancer stereotactic body radiotherapy [PDF]

Physics in Medicine and Biology, 2021, 2021
Dose painting of hypoxic tumour sub-volumes using positron-emission tomography (PET) has been shown to improve tumour control in silico in several sites. Pancreatic cancer presents a more stringent challenge, given its proximity to critical organs-at-risk (OARs) and anatomic motion.
