Dataset of phantom images captured using a multi-flash and a cross polarised probe.
<p>Data captured using two micro camera based imaging probes. One uses a multi-flash technique to eliminate specular reflections. The other uses a cross polarisation technique to overcome specular reflections. Images of embedded features in a multi-layer tissue mimicking phantom are captured using different illumination wavelengths at different depths. </p>

Data from: To eat, or not to eat: A phantom decoy affects information-gathering behavior by a free-ranging mammalian herbivore
<p><span>When foraging, making appropriate food choices is crucial to an animal's fitness. Classic foraging ecology theories assume animals choose food of greatest benefit based on their absolute value across multiple dimensions. Consequently, poorer options are considered irrelevant alternatives that should not influence decision-making among better options. But heuristic studies demonstrate that irrelevant alternatives (termed decoys) can influence decisions of some animals, indicating they use a relative rather than absolute evaluation system. Our aim was to test whether a decoy influenced the decision-making process – i.e. information-gathering and food choice – of a free-ranging mammalian herbivore. We tested swamp wallabies, <em>Wallabia bicolor</em>, comparing their behavior towards, and choice of, two available food options over time in the absence or presence of the decoy. We used a phantom decoy—unavailable option—and ran two trials in different locations and seasons. Binary preferences (decoy absent) for the two available food options differed between trials. Irrespective of this difference, across both trials the presence of the decoy resulted in animals more likely to overtly investigate available food options. But the decoy only shifted food choice, weakly, in one trial. Our results indicate that the decoy influenced the information-gathering behavior during decision-making, providing first evidence that decoys can affect decision-making process of free-ranging mammalian herbivores in an ecologically realistic context. I</span><span>t is premature to say these findings confirm the use of relative evaluation systems. </span><span>Whether the foraging outcome is more strongly affected by other decoys, food dimensions, or ecological contexts, is yet to be determined.</span></p>
Phantom measurement data for 'Myelin water imaging at 0.55 T using a multi-gradient-echo sequence'
<p>This dataset contains the phantom mGRE measurement data used in the submitted article Schäper et al. 'Myelin water imaging at 0.55 T using a multi-gradient-echo sequence'.<br> The acquisitions were done with a 0.55 T MRI system (Magnetom Free.Max; Siemens Healthcare, Erlangen, Germany) using a 12 channel head coil and a 3 T MRI system (Magnetom Prisma; Siemens Healthcare, Erlangen, Germany) using a 20 channel head coil. For further measurement details, please refer to the mentioned original article.</p> <p> </p>
Phantom measurement data for 'Pure balanced steady-state free precession imaging (pure bSSFP)'
<p>This dataset contains the phantom bSSFP phase-cycled measurement data used in the published article: Schäper et al. 'Pure balanced steady-state free precession imaging (pure bSSFP)', Magn Reson Med. 2022;87:1886-1893 (doi: 10.1002/mrm.29086).<br> The acquisitions were made with a 3 T MRI system (Magnetom Prisma; Siemens Healthcare, Erlangen, Germany) using a 20 channel head coil. The data contains four datasets for different TR values (1.5 ms, 3 ms, 5 ms and 8 ms), each was measured with eight phase cycles (0°, 45°, 90°, 135°, 180°, 225°, 270° and 315°).
