Open-source software may aid brain imaging to find disease treatments

Filed under
OSS

Researchers say the open-source software, called PySight, acts as a photon counting add-on for laser scanning microscopes. Because it can image deep into tissue, a laser-based technique known as multiphoton microscopy is often used to study the rapid activity of neurons, blood vessels and other cells at high resolution over time. The method uses laser pulses that excite fluorescent probes, eliciting the emission of photons, some of which are detected and used to form 2D and 3D images.

  • Microscope add-on could be a game-changer for 2D, 3D brain imaging

    Researchers have developed an add-on for laser-scanning microscopes that can improve the quality of 2D and 3D imaging of the brain, according to a new study published in Optica.

    The add-on, called PySight, includes both hardware and open-source software. A laser-based imaging technique called multiphoton microscopy is often used to capture high-quality 2D and 3D images of neurons, blood vessels and other parts of a patient’s brain, the authors observed, but it can be difficult because the images must be taken quickly. This results in fewer photons being visible in the final image.

You can now download zchunk metadata in Rawhide

It’s been a year since I first started working on zchunk, and I’m excited that we’ve finally managed to get it fully integrated into Fedora’s metadata. I’d like to take the opportunity to express my appreciation to Daniel Mach, Jaroslav Mracek and the rest of the DNF team for reviewing and merging my (quite invasive) patches, Michael Schroeder for extensive critiques and improvements on the zchunk format, Igor Gnatenko for help early on, and, finally, Neal Gompa for working behind the scenes to keep things moving.

i.MX8M Mini based handheld dev kit has dual Linux BSPs

Solectrix is prepping an “SX Mobile Device Kit” for developing handhelds with Debian and Yocto Linux BSPs, an i.MX8M Mini SoC, an optional 5-inch touchscreen, WiFi, BT, GNSS, and mini-PCIe, and features for prototyping CSI-2 camera sensors. These days we rarely cover mobile computers, most of which are rugged field-service handhelds that run Android, such as Two Technologies’ N5Print. Yet, Solectrix’s SX Mobile Device Kit (MDK) seemed of particular interest since it’s a development kit with Linux BSPs and NXP’s new i.MX8M Mini SoC. In addition, a Solectrix GmbH rep informed us that optional features like GbE and USB Type-A host and GbE ports enable the MDK to be used as a general-purpose embedded development board. Purchase options range from buying the 125 x 78mm PCB by itself all the way up to a fully equipped handheld with a 5-inch screen. Yocto Project and Debian Linux BSPs are available, and the board also supports Android 9 Pie. Read more Also: i.MX8M and Snapdragon 820E SBCs run Linux and Android
