Augmented reality for teaching undergraduate human anatomy: An educators' perspective

Anatomical Sciences Education, EarlyView.
Abstract The purpose of this study was to explore the perspectives of Australian educators on using augmented reality (AR) as a method for learning human anatomy in the undergraduate health sciences. This will determine the current value of AR and guide future research and development. This prospective qualitative study used a mixed‐methods approach to

Characterization of spatial integrity with active and passive implants in a low-field magnetic resonance linear accelerator scanner

Physics and Imaging in Radiation Oncology
Background and Purpose: Standard imaging protocols can guarantee the spatial integrity of magnetic resonance (MR) images utilized in radiotherapy. However, the presence of metallic implants can significantly compromise this integrity. Our proposed method

Magnetic resonance guided adaptive stereotactic body radiotherapy for lung tumors in ultracentral location: the MAGELLAN trial (ARO 2021-3)

Radiation Oncology, 2022
Background Stereotactic Body Radiotherapy (SBRT) is a standard treatment for inoperable primary and secondary lung tumors. In case of ultracentral tumor location, defined as tumor contact with vulnerable mediastinal structures such as the proximal ...

Phase I study of dose escalation to dominant intraprostatic lesions using high-dose-rate brachytherapy. [PDF]

, 2018
PurposeRadiation dose escalation for prostate cancer improves biochemical control but is limited by toxicity. Magnetic resonance spectroscopic imaging (MRSI) can define dominant intraprostatic lesions (DIL).

CBCT-to-CT synthesis with a single neural network for head-and-neck, lung and breast cancer adaptive radiotherapy

, 2019
Purpose: CBCT-based adaptive radiotherapy requires daily images for accurate dose calculations. This study investigates the feasibility of applying a single convolutional network to facilitate CBCT-to-CT synthesis for head-and-neck, lung, and breast ...

Towards real-time motion estimation for MR-guided radiotherapy

, 2023
The ultimate potential of the MR-linac is real-time adaptive MR-guided radiotherapy (aMRgRT), i.e. adapt the radiation plan in real-time according to real-time 3D motion estimates. One of the major technical roadblocks towards achieving this goal is the real-time 3D motion estimation. This thesis presents two new approaches in this context.

Reprogramming tumor immune microenvironment by ultrasound‐responsive nanoplatforms for enhanced cancer immunotherapy

BMEMat, EarlyView.
Ultrasound‐responsive nanoplatforms reprogram the tumor immune microenvironment by targeting tumor cells, immune cells, and non‐immune stromal cells to enhance the efficacy of cancer immunotherapy. Abstract Cancer immunotherapy represents a significant advancement in cancer treatment by enhancing the specific recognition and elimination of cancer cells.
