An ophthalmic surgical system includes an imaging unit configured to generate a fundus image of an eye and a depth imaging system configured to generate a depth-resolved image of the eye. The system further includes a tracking system communicatively coupled to the imaging unit and depth imaging system, the tracking system comprising a processor and memory configured to analyze the fundus image generated by the imaging unit to determine a location of a distal tip of a surgical instrument in the fundus image, analyze the depth-resolved image generated by the depth imaging system to determine a distance between the distal tip of the surgical instrument and a retina of the eye, generate a visual indicator to overlay a portion of the fundus image, the visual indicator indicating the determined distance between the distal tip and the retina, modify the visual indicator to track a change in the location of the distal tip within the fundus image in real-time, and modify the visual indicator to indicate a change in the distance between the distal tip of the surgical instrument and the retina in real-time.

Methods and apparatuses, including devices and systems, for remote and detection and/or diagnosis of acute myocardial infarction (AMI). In particular, described herein are handheld and adhesive devices having an electrode configuration capable of recording three orthogonal ECG lead signals in an orientation-specific manner, and transmitting these signals to a processor. The processor may be remote or local, and it may automatically or semi-automatically detect AMI, atrial fibrillation or other heart disorders based on the analyses of the deviation of the recorded 3 cardiac signals with respect to previously stored baseline recordings.

Medical diagnostic devices and related methods of use are described in which one or multiple coils in a sensor, each coil connected with an RLC circuit and frequency counter, are held against a patient's head at predetermined cranial locations. Frequencies of the RLC circuit are measured and compared against those taken from known, control heads, to determine whether there is a medical problem and what type of problem. In some instances, too high of frequencies can reveal pooled blood in the head, a sign of hemorrhagic stroke, while too low of frequencies imply lack of blood supply, a sign of ischemic stroke. A head-mountable frame can assist a first responder in securing and guiding the coils and, along with fiducials, allow for automatic comparison of frequencies with the correct control data.

A component analyzing apparatus is provided. The component analyzing apparatus includes: an impedance measurer including: a plurality of electrodes having an electrode width that is determined based on an effective measurement depth for analyzing a component of an analyte and a gap between two electrodes among the plurality of electrodes, and an electrode controller configured to apply a first current to a first electrode and a second electrode among the plurality of electrodes and configured to measure impedance based on a voltage between a third electrode and a fourth electrode; and a processor configured to analyze the component of the analyte based on the impedance measured by the electrode controller.
