We describe a super-resolution imaging method to probe the structural organization of the bacterial FtsZ-ring, an essential apparatus for cell division. This method is based on quantitative analyses of photoactivated localization microscopy (PALM) images and can be applied to other bacterial cytoskeletal proteins.

We are developing a dynamic adaptive exposure technique using our scanning beam digital X-ray system. Rather than exposing an object uniformly, the exposure is adapted depending on the opacity of the object. Here we show an experiment on an anthropomorphic phantom that resulted in a dose saving of 30%.

This article presents a comprehensive protocol for PmbExM, an Expansion Microscopy technique designed specifically for Proteus mirabilis biofilms. PmbExM utilizes a stepwise enzymatic treatment of biofilm samples to achieve an isotropic, 4.3-fold expansion, enabling super-resolution analysis of the spatial organization of cellular and subcellular structures within these sessile microbial communities.
FAQs
The decision depends on three inputs identified by the system: image content, viewing conditions, and operating requirements. Algorithms examine regions to determine where fine features or regions of interest matter most. Those areas receive increased resolution, while less informative regions can be reduced. This directs pixels and data toward information with greater visual or analytical value.
These methods provide different ways to implement selective detail allocation. Resampling changes the spatial detail assigned to image content, tiling lets a system handle regions separately, and multiscale representations organize information at different detail levels. Together, they support spatially variable image handling rather than requiring every region to receive identical resolution.
Resolution can change according to the content being represented, the conditions under which the image is viewed, and the requirements of the operating system. Fine features or designated regions of interest may justify higher detail, whereas less informative areas may tolerate reduction. The resulting allocation balances preservation of important visual information against storage, bandwidth, processing, or display demands.
A basic workflow begins by analyzing image regions and identifying content or regions of interest that require greater detail. The system then applies a suitable representation, such as resampling, tiling, or a multiscale structure, while reducing detail elsewhere. Engineers evaluate the resulting allocation against storage, transmission, processing-time, and display constraints to support efficient image handling.
Its applications span medical and scientific imaging, machine vision, remote sensing, video streaming, and resource-constrained devices. In these settings, selective detail allocation can lower transmission bandwidth, storage needs, processing time, or display demands while preserving important information. The benefit is especially relevant when systems must handle images efficiently and maintain responsive operation.
Engineering systems often need to balance image quality with limited computational, communication, storage, or display resources. Allocating higher resolution only where it matters can reduce unnecessary data and processing while retaining important visual information. This makes the approach relevant to system responsiveness and efficient image handling across imaging, streaming, sensing, and embedded-device applications.
