چکیده

The adverse side effects of gamma-ray radiotherapy can be reduced significantly by combining the treatment system with a real-time imaging system, used to precisely steer the radiation beam. MRI is a particularly attractive imaging modality for this, due to its excellent soft tissue contrast. A project is underway to combine a cylindrical, closed bore high-field MRI system with a 6 MeV Linac radiation source (fig. 1) [1]. A key feature of the concept is that the Linac is located on the outside of the MRI magnet. The gamma beam passes through the scanner to reach the patient inside the bore. This abstract describes some of the modifications to the MRI scanner needed to make it compatible with this application.

PET and MRI-guided focused ultrasound surgery for hypoxic-tissue ablation combined with radiotherapy in solid tumors

Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...

Dosimetric and Radiobiological Evaluation of Multiparametric MRI-guided Dose Painting in radiotherapy of Prostate Cancer

Introduction: Radiotherapy is one of the treatment options for locally advanced prostate cancer, however with standard radiation doses it is not always very effective. One of the strategies to improve the efficiency of radiotherapy is increasing the dose. In this study to increase tumor local control rates a new radiotherapy method, known as dose painting (DP) was investigated....

Design of a Whole-Body Radio Frequency Coil for image-guided radiotherapy treatment in a MRI-LINAC system

INTRODUCTION: Radiotherapy is a primary cancer treatment modality. However, targeting a radiation beam on tumours in moving organs such as liver, stomach or lungs, without damaging healthy tissue can be challenging. For this reason, Magnetic Resonance Imaging (MRI) and Linear Accelerator (LINAC) are being combined as a MRI-LINAC, a new image-guided radiotherapy treatment capable to both image a...

The Use of Sectional Imaging with CT and MRI for Image-Guided Therapy

Sectional imaging is integrated in each link of the modern radiotherapy chain, from diagnostic procedures to target volume definition to treatment planning, dose delivery, and verification. While CT is widely used for modern EBRT, including intensity modulated radiotherapy (IMRT) and image-guided radiotherapy (IGRT), MRI represents the gold standard for IGBT for gynecological malignancies (see ...

Calculation of total dose and dose equivalent distribution in the treatment of lung cancer using MR-guided carbon therapy

Nowadays, in order to improve the accuracy of treatment in radiation therapy, there are many attempts to use magnetic resonance imaging (MRI) due to the advantages of excellent soft tissue contrast and ultra-fast pulse sequences. On the other hand, carbon-ion radiation therapy is developing rapidly due to the benefits of greater relative biological effectiveness (RBE) and the application in the...
