The optical system has distal and proximal ends, and includes an image sensor (32), positioned at the proximal end of the optical system. The optical system also includes an optical member (34) having distal (36) and proximal ends, and shaped so as to define: (a) a lateral surface, at least a distal portion of which is curved, configured to provide omnidirectional lateral viewing, (b) a distal indentation (44) in the distal end of the optical member, and (c) a proximal indentation (48) in the proximal end of the optical member. The optical system also includes a convex mirror (40), coupled to the distal end of the optical member, and shaped so as define an opening through which the distal indentation passes. A distal lens (52) is positioned distal to the mirror. The optical member, the mirror, and the distal lens have respective rotational shapes about a common rotation axis.

摘要： A method of finding an indication of a degree of cerebro-vascular bilateral asymmetry in a subject, comprising: a) measuring a first impedance waveform and a second impedance waveform of the subject's head as functions of time, in each case by finding a potential difference between two voltage electrodes associated with passing a given injected current through the head between at least two current electrodes, wherein in each case the voltage electrodes are located asymmetrically on the head, or the current is injected asymmetrically into the head, or both, and wherein the locations of the voltage electrodes and the distribution of current injection in measuring the second impedance waveform are minor images of what they are in measuring the first impedance waveform; and b) finding the indication of the degree of bilateral asymmetry from a difference between characteristics of the first and second impedance waveforms.

摘要： Devices, and methods for synchronizing cerebro-hemodynamic signals are disclosed. In one aspect, the devices and methods may include synchronizing first and second signals indicative of hemodynamic characteristics within a subject's brain. Differences may be determined between the synchronized signals and used to provide information for diagnosing changes in arterial occlusion. Differences between the synchronized signals may include differences, such as timing delays, between signature features of the synchronized signals. The first and second signals may be indicative of hemodynamic characteristics in first and second hemisphere's of a subject's brain. The first and second signals may be bioimpedance signals.
