Abstract
The invention relates to a medical imaging system. First, a sequence of images (SQ) of an organ (HRT) is acquired. Then, a region of tissue (PT) on said sequence of images and a parameter (P) characteristic of the motion of said region of tissue (PT) are defined. A set of phases (PH) characteristic of a cardiac cycle based on said parameter (P) is then defined. Finally, a local myocardial performance index (LMPI) for said region of tissue (PTR) based on said set of phases (PH) is computed.
Claims11
A system, comprising a controller (CTRL) for controlling the following operations:
- Acquisition of a sequence of images (SQ) of an organ (HRT),
- Determination of a region of tissue (PT) on said sequence of images,
- Determination of a parameter (P) characteristic of motion of said region of tissue (PT),
- Determination of a set of phases (PH) characteristic of a cardiac cycle based on said parameter (P),
- Computation of a local myocardial performance index (LMPI) for said region of tissue (PTR) based on said set of phases (PH).
A system as claimed in the preceding claim, wherein the determination of another region of tissue uses a line (LX) along the organ.
A method for medical imaging, comprising the steps of:
- Acquiring a sequence of images (SQ) of an organ (HRT),
- Determining a region of tissue (PT) on said sequence of images,
- Determining a parameter (P) characteristic of motion of said region of tissue (PT),
- Determining a set of phases (PH) characteristic of a cardiac cycle based on said parameter (P),
- Computing a local myocardial performance index (LMPI) for said region of tissue (PT) based on said set of phases (PH).
A method for medical imaging as claimed in the preceding claim, further comprising a step of selecting the region of tissue (PT) by visual assessment.
