Fall 2015
With the advent and development of hybrid Linac-MR technology, we will be able to track and treat lesions in real time. This will permit the narrowing of radiotherapy margins and escalation of dose, augmenting the therapeutic outcome of radiotherapy. The addition of a magnetic field to the...

Dynamic tumour-tracked radiotherapy is a promising method for delivering conformal doses to tumours that exhibit a large degree of motion as a result of patient respiration. However, there exists an inevitable latency between the acquisition of an image of a moving tumour and the adaptation of...

Fall 2016
The integration of clinical linear accelerators (linacs) with magnetic resonance imaging (MRI) systems represent the next generation of image guidance technologies in radiotherapy. Linac-MR systems have several potential advantages over the current X-ray based state-of-the-art image guidance...

Fall 2011
The integration of a clinical linear accelerator (linac) with a magnetic resonance imager (MRI) will offer real time images during treatment, making tumor tracking possible. One of the challenges of the integration is removing any mutual interference between the two systems. Methods of removing...

Keyvanloo Shahrestanaky, Amirmohamad
The integration of a clinical linear accelerator (linac) with a magnetic resonance imaging (MRI) system would provide real-time tumor tracking. The magnetic fields of linac-MR systems modify the path of contaminant electrons in photon beams, which alters patient skin dose. In this work, we used...

Magnetic resonance imaging (MRI) can visualize solid tumours in real time and its integration with a linear accelerator offers the possibility to track tumours during irradiation. However, irradiating a patient inside a linac-MR poses several challenges. MRI uses radiofrequency (RF) coils to...
