1. A method of indicating a bilateral hematoma condition comprising:
- determining an optical density associated with a plurality brain locations on a right side of a patient'"'"'s head;
determining a first optical density difference between two of the plurality of brain locations on the right side of the patient'"'"'s head;
determining an optical density associated with a plurality brain locations on a left side of the patient'"'"'s head;
determining a second optical density difference between two of the plurality of brain locations on the left side of the patient'"'"'s head; and
indicating bilateral hematoma based upon a comparison of the first optical density difference and the second optical density difference to a predetermined optical density difference range.

2. A method of indicating hematoma comprising:
-
determining an optical density difference for at least one pair of contralateral head locations; comparing said optical density differences to a predetermined range of optical density differences; and diagnosing a hematoma condition in each of the contralateral head locations based upon the relationship between the optical density differences and the predetermined range of optical density differences. - View Dependent Claims (3)

4. A system for detection of hematoma comprising:
-
a handheld probe having a source of infrared light, a detector of infrared light; and
a light guide assembly including a base, a source light guide that transmits infrared light from the source to a tissue region, and a detector light guide that transmits at least a portion of the infrared light passing through the tissue region to the detector, wherein the source light guide and the detector light guide are each secured to the base; anda processor linked to the probe, configured to provide instructions to the probe and configured to process data transmitted by the probe, the processor having a display for indicating the presence of hematoma based upon a characteristic of the infrared light passing through the tissue. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
