Tympanic thermometers accurately measure fever. These thermometers also measure the thermal radiation emitted from the TM & the ear canal and give accurate reading within one second. These thermometers incorporate self diagnosis technology and temperature compensation technology.

A typical stereotactic frame consists of a rigid head-mounted frame, whose purpose is to provide a rigid fiducial marker system during imaging, as well as a rigid platform for mounting instruments during surgery. The set of fiducial markers is visualized with the respective imaging modalities and provides a coordinate system within which targets appearing in the images may be localized. The frame also provides the means for determining coordinate trasformations between frame-space and image-space.
