Meningiomas are among the most common primary tumors of the central nervous system. We describe the case of an 82-year-old woman with meningioma, the epicenter of which was above the sella, causing her terrible headaches and severely compromised visual acuity. Although the patient was eligible for stereotactic radiosurgical treatment (SRS), she was treated with conventional 3D conformal radioth...

BACKGROUND Three-dimensional conformal radiation therapy (3DCRT)/intensity-modulated radiation therapy (IMRT) combined with or without transcatheter arterial chemoembolization (TACE) for locally advanced hepatocellular carcinoma (HCC) has shown favorable outcomes in local control and survival of locally advanced HCC. However, intra-hepatic spreading and metastasis are still the predominant trea...

A 16-year-old male presented with constipation, acute retention of urine and abdominal swelling associated pain. Per-rectal examination revealed painful growth in lateral anterior wall rectum 4cm from anal verge. X-ray erect abdomen was done which showed Indistinct bowel gas pattern suggestive Intestinal obstruction. Diversion transverse colostomy view intestinal Investigations large well defin...

Introduction: The close proximity of the rectum tissue to the prostate gland results in rectal toxicity during prostate radiotherapy. Rectal Retractor (RR) is a rectal displacement technique that inserts into the rectum, as a result, the lateral and dorsal part of the rectal wall push away from high dose areas. The aim of this study was to investigate the dosimetric consequence...

Respiratory motion has been considered a clinical challenge for lung tumor treatments due to target motion. In this study, we aimed to perform an experimental evaluation based on dynamic phantoms using MLC-based beam tracking. TrackBeam, a prototype real-time beam tracking system, has been assembled and evaluated in our clinic. TrackBeam includes an orthogonal dual-layer micro multileaf collima...

A practical and accurate generalized procedure to reconstruct the isocenter dose D(iso) for 3D conformal radiotherapy (3DCRT) has been developed for X-ray open beams supplied by linacs of different manufacturers and equipped with aSi electronic portal imaging devices (aSi EPIDs). This paper reports an extension of the method, to be applied at the wedged X-ray beams characterized by the wedge at...
