Methods and apparatus are provided for non-invasive blood analysis. A blood analysis device (10, 30) comprises a housing (24) for receiving a human or animal body part or a container of blood. The housing (24, 32) comprises at least one wave emitter (18) for emitting an emitted wave to target blood, and at least one wave sensor (26) for sensing a response wave after the emitted wave has interacted with the target blood. The at least one wave sensor is configured to output at least one sense signal allowing a frequency spectrum of the emitted wave to be constructed.

Methods for diagnosing and/or treating a multi-lesion intravascular region are disclosed. The methods may include advancing a pressure sensing device to a first position that is distal of a first lesion and that is distal of a second lesion, proximally retracting the pressure sensing device to a second position that is proximal of the first lesion and that is proximal of the second lesion, calculating a first estimated post-treatment fractional flow reserve based on treatment of the first lesion, calculating a second estimated post-treatment fractional flow reserve based on treatment of the second lesion, and treating the first lesion, the second lesion, or both based on the first estimated post-treatment fractional flow reserve and the second estimated post-treatment fractional flow reserve.

Provided is a method of representing a pressure variation in an object on an image of the object. The method includes: measuring all velocity components of the object; selecting a first position on the image of the object; estimating a pressure variation between the first position and a second position that is separate from the selected first position; and displaying an estimated pressure variation on the image of the object by using a predetermined indicator.
