The apparatus and methods disclosed herein relate to diagnosis of disease through the detection of signals from portions of a body. The signals may be acoustic signals, which can be used to diagnose the presence, severity and/or location of occlusions in arteries, such as the coronary arteries. The signals may be detected through noninvasive methods such as, for example, passive reception. Such methods can avoid many of the problems associated with invasive angiogram and angioplasty procedures. The apparatus and methods described herein are not limited to use for diagnosing occlusions in the coronary arteries, but can be used for a wide variety of biomedical diagnosis in human and nonhuman animals.
