2016
A scanner for imaging magnetic particles in planar samples was developed using the planar frequency mixing magnetic detection technique. The magnetic intermodulation product response from the nonlinear nonhysteretic magnetization of the particles is recorded upon a two-frequency excitation. It can be used to take 2D images of thin biological samples.

Despite an increase in the use of structural and functional magnetic resonance imaging (fMRI) in humans, the study of young pediatric populations remains a challenge. We present a hands-on, step-by-step video protocol including guidelines for clinicians and researchers intending to perform (f)MRI in young children.
FAQs
Familiarization reduces uncertainty by allowing participants to experience the scanner-like bore, patient table, lighting, and operating sounds before an actual study. They can rehearse remaining still and become accustomed to the confined environment. This preparation may reduce anxiety and improve readiness for procedures in which participant movement could compromise the quality of the collected data.
Recorded sounds add realistic sensory cues to the physical practice environment. Participants can learn how the procedure feels and sounds while focusing on staying still, rather than encountering those features for the first time during an imaging session. This makes the rehearsal more representative of the conditions that may influence comfort and motion-related behavior.
A practice session provides an opportunity to observe whether an individual can remain still in a confined, scanner-like setting. Researchers can identify motion-related difficulties before collecting study data and use that information to improve participant preparation. The approach is particularly relevant when reliable, motion-free measurements are needed for biomedical or behavioral experiments.
The replica reproduces important physical and procedural features without producing a diagnostic scan and, in many cases, without generating a strong magnetic field. Its purpose is rehearsal, familiarization, and behavioral assessment rather than image acquisition. This distinction allows researchers to focus on participant responses and preparation before the actual imaging procedure.
A participant uses the scanner-like bore and patient table while experiencing the arranged lighting and recorded operating sounds. The session emphasizes becoming comfortable with the confined space and practicing stillness. Researchers can use this structured exposure to prepare individuals for an imaging protocol and to note behaviors that may affect participation or data collection.
Mock scanners are especially useful in pediatric research, where unfamiliar equipment or confined spaces may make participation difficult. They also support behavioral experiments and biomedical studies that depend on consistent, motion-free data. By adding a preparation stage, investigators can address participant readiness before beginning the associated magnetic resonance imaging protocol.
