Huang C, Ackerman JL, Petibon Y, Normandin MD, Brady TJ, El Fakhri G, Ouyang J. Motion compensation for brain PET imaging using wireless MR active markers in simultaneous PET-MR: phantom and non-human primate studies.
Weight loss and known side effects are more likely markers for "wireless" monitoring of HIV status.
Physiological tests such as colonic transit study with radio-opaque markers or wireless motility capsule, anorectal manometry, and balloon expulsion tests can identify disorders of colonic and anorectal function.
Extensive experiments illustrate that the proposed system achieves equivalent performance as popular wireless inertial sensors and a marker-based optical system, but without limitations commonly associated with such traditional systems.
From this consideration, the importance of the use of restart markers is clear in a wireless network, in which noise and interferences may be relevant.
Specific marker positions were located by wireless communication using a wand-shaped probe with a 30-mm communication range, with the distance to the marker indicated by gradual changes in sound pitch.
Currently available colon transit studies include the radiopaque markers (ROM), colonic scintigraphy, and the wireless motility capsule (WMC).
In this cross-sectional study we investigated the possible association between self-reported use of wireless telephones and serum TTR concentrations as a marker of alterations in CSF TTR, possibly reflecting an effect of RF.
The initial aim of the present study was to analyze serum S100B levels as a marker of BBB dysfunction and use of wireless telephones.
Interestingly, the marker inside the body does not need to transmit any wireless signal.
