Multiplexed ion beam imaging (MIBI) is often used to image tissue microarrays and tiled, contiguous tissue areas, but current software for setting up these experiments is cumbersome. The tile/SED/array interface is an intuitive, interactive graphical tool developed to dramatically simplify and accelerate MIBI run setup.

Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

Dynamic computer-aided implant surgery (DCAIS) is a controlled implant surgical placement method performed without a surgical template using optical control. The real-time intraoperative control of movement and position of the surgical device simplifies the procedure and gives more freedom to the surgeon, providing similar precision as static navigation methods.

Source: Laboratory of Dr. B. Jill Venton - University of Virginia Calibration curves are used to understand the instrumental response to an analyte and predict the concentration in an unknown sample. Generally, a set of standard samples are made at various concentrations with a range than includes the unknown of interest and the instrumental response at each concentration is recorded. For more accuracy and to understand the error, the response at each concentration can be repeated so an error...

DNA tiling is an effective approach to make programmable nanostructures. We describe the protocols to construct complex two-dimensional shapes by the self-assembly of single-stranded DNA tiles.
FAQs
The tile’s known reflectance, color, or other optical properties provide a reference against which the recorded scene can be assessed. Because the tile is captured under the same illumination and viewing conditions, differences caused by sensor response or lighting can be identified and corrected rather than mistaken for properties of the environment. This reference strengthens measurement consistency across images.
Known optical properties give researchers a stable reference within the image or sensing record. Comparing the tile’s recorded appearance with its expected properties helps reveal effects from sensor response, lighting variation, or changes in image intensity. Correcting for these influences improves the reliability of measurements and makes results less dependent on uncontrolled differences in the recording environment.
Calibration helps separate environmental signal from measurement artifact. When image intensity changes, a calibrated record gives researchers a reference for judging whether the change reflects the scene or instead results from sensor behavior or lighting variation. This distinction is especially important when comparing observations collected at different locations or dates, where uncorrected differences could reduce confidence in environmental interpretation.
Begin by positioning a tile with known optical properties within the scene or sensing environment, then record it with the surrounding subject under the intended illumination and viewing conditions. Use that paired record to support correction of the image or sensor measurements before comparing environmental observations. Consistency in placement and recording conditions is central to repeatability.
Calibration Tile Placement supports several environmental measurement approaches, including field photography, spectroscopy, remote sensing, and photogrammetry. In each case, the reference tile supplies a known optical point within the recorded scene. That information can improve the reliability of measurements when researchers need to evaluate color, reflectance, image intensity, or related optical observations under changing field conditions.
When observations are collected across sites or dates, consistent calibration provides a common basis for comparison. Researchers can use the tile record to account for sensor response and lighting-related differences, making it easier to distinguish actual environmental change from acquisition artifacts. The resulting comparisons are more defensible because variation in the measurement setup is considered alongside variation in the environment.
