First Claim
1. A method for diagnosing a clinical state of a portion of a body of a subject, comprising:
- (1) directing toward the portion a first pulse of electromagnetic energy;
(2) while the portion is in a functional state due to the first pulse of electromagnetic energy, directing toward the portion a second pulse of electromagnetic energy;
(3) detecting, at a second-pulse time, energy of the second pulse of electromagnetic energy that is reflected from the portion;
(4) while the portion is in a functional state due to the first and second pulses of electromagnetic energy, directing toward the portion a third pulse of electromagnetic energy;
(5) detecting, at a third-pulse time, energy of the third pulse of electromagnetic energy that is reflected from the portion;
(6) in response to detecting the pulse of electromagnetic energy at the second-pulse time and the third-pulse time, quantifying a characteristic of the portion resulting from (a) the functional state due to the first pulse of electromagnetic energy and (b) the functional state due to the first and second pulses of electromagnetic energy; and
(7) identifying a clinical state of the subject in response to quantifying the characteristic of the portion.

Abstract
A method includes directing toward a portion of a subject'"'"'s body a first pulse of electromagnetic energy. While the portion is in a functional state due to the first pulse, a second pulse is directed toward the portion. At a second-pulse time, reflected energy due to the second pulse is detected. While the portion is in a functional state due to the first and second pulses, a third pulse is directed toward the portion. At a third-pulse time, energy of the third pulse, reflected from the portion, is detected. In response to detecting the pulses at the second-pulse time and the third-pulse time, a characteristic of the portion is quantified resulting from (a) the functional state due to the first pulse and (b) the functional state due to the first and second pulses. A clinical state of the subject is identified. Other embodiments are described.
