High technology in radiation therapy
This work was to develop a reconstruction method for theranostic dosimetry by improving the spatial resolution and noise properties of reconstructed SPECT images (SPECTRE). Single Photon Emission Computed Tomography (SPECT) is commonly used to evaluate the radiation dose delivered to target structures and normal organs in radionuclide therapy (RNT). But Read more…
Researchers and patients alike are benefiting from a new imaging technology called ‘Long Axial Field of View (FOV) Positron Emission Tomography’, also known as ‘Total-Body PET (TB-PET)’. This technology advance enables molecular imaging studies to be performed at ultrahigh sensitivity, i.e. an order of magnitude or more higher sensitivity than Read more…
Palliative external beam radiotherapy plays an important role in the palliation of symptoms such as pain and bleeding caused by incurable cancers. Despite this, approximately 1/4 to 1/3 of patients do not receive symptom relief and for the ones that do respond, symptoms can return requiring further treatment …… Read Read more…
The ABC News Report, 14 March 2022: Members may not have seen the recent television coverage of ‘3D Printing for Cancer Patients’ at the Herston Biofabrication Institute. Scott Crowe’s article, 3D printing for radiotherapy, published in our Better Healthcare Technology website (July, 2021), is a member of this research group. Read more…
The goal of prostate radiation therapy The goal of radiotherapy when treating patients with localised prostate cancer, is to distribute sufficient radiation dose to eradicate the tumour and as little as possible to all parts of the surrounding healthy tissues. Clinicians want to make sure that enough radiation dose reaches Read more…
More than half of all cancer patients receive radiotherapy as part of their treatment and, for patients receiving radiotherapy alone, the average cure rate is 40%. Cancer cells are killed by X-ray ionisation of the DNA and other associated biological effects. But, under certain circumstances, the radiation exposure can also Read more…
Radiation therapy aims to optimise the conformity of lethal dose to the tumour target while limiting as much as possible radiation-induced side effects to surrounding healthy tissue. Consequently, there has been an escalation in the type of treatments that use a combination of small, irregularly-shaped high-dose beams of megavoltage (MV) Read more…
Advances in 3D print technologies and the development of easy-to-use computer-aided design solutions during the past two decades has provided a positive impact on the manufacturing of parts and components in the healthcare industry. The new 3D print technology enables health professionals to make………….Read more
Having spent over 50 years of work providing healthcare for cancer patients, I suddenly found myself on the receiving end. Unexpected cancer had thrust me into emergency surgery. It required some immediate skilled surgical and nurse expertise to treat and take me back on the road to recovery. Read more……. Read more…
An electronic portal imaging device (EPID) is routinely fitted as a radiotherapy linear accelerator accessory. The EPID can be used to verify the multi-leaf collimator (MLC) leaf positions and other quality assurance (QA) type tasks. EPID-based MLC has been extensively studied for position error detection of large fields and using Read more…
