Method and system for performing an imaging scan of a subject
A method for performing an imaging scan of a subject includes positioning a narrow field-of-view camera at a first imaging position to acquire a first set of imaging information of a first object of interest, positioning the narrow field-of-view camera at a second imaging position to acquire a second set of imaging information of a second object of interest, determining emission counts for the first and second sets of imaging information, and utilizing the determined emission counts to generate a value that indicates a probability of a successful medical procedure being performed on the subject.
1. A medical imaging system comprising:
a narrow field of view camera;
a controller configured to position the narrow field of view camera, the controller configured to re-position the narrow field of view camera from a first imaging position to a second imaging position that is different from the first imaging position; and
a processor coupled to the narrow field-of-view camera, the processor instructed by a set of instructions directing the processor to:
acquire a first set of imaging information of a first object of interest while the narrow field-of-view camera is positioned at the first imaging position;
acquire a second set of imaging information of a second object of interest that is different from the first object of interest while the narrow field-of-view camera is positioned at a second imaging position, wherein the first object of interest is a heart, and the second object of interest is a mediastinum;
determine corresponding emission counts seperately for the first and second sets of imaging information;
calculate a ratio of the emission count for the first set of imaging information to the emission count for the second set of imaging information;
compare the ratio to a predetermined threshold value; and
determine that a medical procedure has a higher likelihood of success if the ratio is larger than the predetermined threshold value, and that the medical procedure has a lower likelihood of success if the ratio is lower than the predetermined threshold value.
2. The medical imaging system of claim 1 , wherein the narrow field of view camera comprises a plurality of pinhole cameras.
3. The medical imaging system of claim 1 , wherein the narrow field of view camera comprises a nuclear medicine camera including a plurality of detector modules mounted on a single housing, each of the detector modules including a pinhole collimator.
4. The medical imaging system of claim 1 , wherein the processor is further configured to acquire the first and second sets of imaging information after the subject is injected with a metaiodobenzylguanidine (mIBG) radiotracer.
5. The medical imaging system of claim 1 , wherein the value is a heart-to-mediastinum ratio.
6. The medical imaging system of claim 1 , wherein the medical procedure comprises a defibrillator implantation procedure.
7. The medical imaging system of claim 1 , wherein the second object is outside of a field of view of the narrow field-of-view camera when the narrow field-of-view camera is in the first position, and the first object is outside the field of view of the narrow field-of-view camera when the narrow field-of-view camera is in the second position.
