RADIOACTIVE-EMISSION-MEASUREMENT OPTIMIZATION TO SPECIFIC BODY STRUCTURES

Spectrum Dynamics Medical...

1. A camera for imaging of radiation emitted from a patient that includes:at least one assembly comprising a plurality of heads, where each head comprises: at least one pixilated solid-state detector configured to detect photons emitted from the body during image acquisition and collimated to define one or more collection angles for pixels of said detector; and
one or more actuators configured to control the position and orientation of at least one of said heads relative to the assembly, during image acquisition,
wherein at least one of the heads is configured to be translated forward to be in close proximity to said body, relative to said assembly, along a general direction that the head is aimed at during image acquisition and to change its viewing direction by repeated oscillatory motion, where data is acquired during said oscillatory motion.

SYSTEMS AND METHODS FOR COMPUTATION OF FUNCTIONAL INDEX PARAMETER VALUES FOR BLOOD VESSELS

Spectrum Dynamics Medical...

1. A computer implemented method for calculation of a functional index parameter in at least one blood vessel of a patient, comprising: receiving, by a processor, a dataset of registered functional image data and anatomical image data, wherein the functional image data and the anatomical image data include data indicative of anatomical and functional data for at least one blood vessel of a certain patient; calculating, by the processor, at least one value for at least one functional index parameter based on the functional image data of the dataset, for at least one of: (i) at least one blood vessel, and (ii) for the anatomical region of the at least one blood vessel; outputting, by the processor, the calculated at least one value for the at least one functional index parameter for the at least one blood vessel of the certain patient; computing, by the processor, a flow related value using a mathematical model, based on anatomical imaging data of the patient without registered nuclear imaging data; and identifying, by the processor, a mismatch between the flow related value and the at least one value of the functional index parameter, the mismatch potentially indicative of microvascular disease in the at least one vessel.
