Université Laval medical physics professors and students in action at AAPM2017

This week, our students and faculty are involved in 17 presentations at the AAPM meeting in Denver, Colorado. This include Best In Physics (Therapy) Marie-Ève Delage. Overall 2 general poster presentations, 5 poster discussions (ePoster), 3 SNAP Oral, 5 oral presentations and two symposium presentations.

A new list of predatory (blacklist) journals is available…for a fee

Beall’s list of predatory journals has found a “commercial” replacement. Let’s see how much it will cost to access.

Money to acquire new state-of-the-art equipment. Will expand our research program and enable new graduate student projects.

 

Exciting!

New opening for MSc and PhD students in our research group

See the announcement in French and English for all the details. Our graduate program is CAMPEP accredited. Please note that formal teaching is done in French but research activities can be conducted in English.

We are located in the middle of the Old Quebec City, classified as a UNESCO world heritage treasure.

New publication by our group on Quantum Dots as radiation nano-dosimeters.

Systematic characterization of semiconductor colloidal quantum dots (cQDs) response to ionizing radiation must be performed to use them in radiation detection. In this study, the robustness of multi-shell (MS) and core/shell (CS) cQDs was investigated under irradiation. Radioluminescence (RL) measurements with kV and MV photon beams revealed a better resistance of MS cQDs to ionizing radiation, with their spectra fluctuating by barely ∼ 1 nm. A systematic signal recovery between subsequent irradiations was noticed for MS cQDs only. A beam energy dependence of the RL stability was detected between kV and MV energies. At the same point of dose cumulated, the RL signal loss for the kV beams was observed to be ∼6-7% smaller than that of the MV beam, for both types of cQDs. These results demonstrate that MS cQDs are better candidates as ionizing radiation sensors than CS cQDs, especially in the kV energy range.

PLOS ONE: How Many Is Too Many? On the Relationship between Research Productivity and Impact

Clearly if you do not published, you can never be cited…However, interesting to see that the Natural sciences field seems to taper-off more quickly than the life science field.

A MR Imaging primer through analogy with Guitar playing

Thanks to my colleague Jerry Battista from the University of Western Ontario, understanding the basic MR pulse sequence (a not so obvious topic especially if you have to design such a sequence) is now easier than ever. For those who do not know Prof. Battista also developed a mini-CT scanner (using non-ionizing radiation!) to teaching the basic of medical imaging from high-school all the way to university. We are using this scanner in our undergraduate laboratory.

 

So, check out this wonderful and accessible teaching YouTube Video: Understanding an MRI Pulse Sequence using a Guitar.

Luc Beaulieu on brachytherapy research!

Here is a BrachyTalk interview I gave during the 2016 ESTRO meeting in Torino,  Italy. Get to know what I am working on and my (physics and biomedical technology) vision of the field.

Thanks to the peoples at BrachyAcademy for making me look good during that interview 😉

The CIHR gong show – a ridiculous state of affairs | Affaires Universitaires

The last month has been a pretty topsy-turvy one for the Canadian Institutes of Health Research. After it rolled out the first round of applications for its new operating grant application termed “project grants,” it was all set to deliver evidence that its new systems of financial allocation and peer review were superior to the […]

How much time does it really take?

To present a scientific subject in an attractive and stimulating manner is an artistic task, similar to that of a novelist or even a dramatic writer. The same holds for writing textbooks.
– Max Born

When a graduate student come to me with the big news that its abstract has been selected for an oral presentation, my first reaction is a big congratulations and the second is to already set a deadline for a first version of the talk. Because of the abstract, you already know the content, what needs to be presented. But crafting an effective 7, 8 or 10 minutes presentation is a complete new game.
