SYSTEMS AND METHODS FOR DYNAMIC SCANNING WITH MULTI-HEAD CAMERA

摘要

A nuclear medicine (NM) multi-head imaging system is provided that includes a gantry, plural detector units mounted to the gantry, and at least one processor operably coupled to at least one of the detector units. The detector units are mounted to the gantry. Each detector unit defines a detector unit position and corresponding view oriented toward a center of the bore. Each detector unit is configured to acquire imaging information over a sweep range corresponding to the corresponding view. The at least one processor is configured to, for each detector unit, determine plural angular positions along the sweep range corresponding to boundaries of the object to be imaged, generate a representation of each angular position for each detector unit position, generate a model based on the angular positions using the representation, and determine scan parameters to be used to image the object using the model.

1. A nuclear medicine (NM) multi-head imaging system comprising:
a gantry defining a bore configured to accept an object to be imaged; plural detector units mounted to the gantry, each detector unit defining a detector unit position and corresponding view oriented toward a center of the bore, each detector unit configured to acquire imaging information over a sweep range corresponding to the corresponding view; and at least one processor operably coupled to at least one of the detector units, the at least one processor configured to:
for each detector unit, determine plural angular positions along the sweep range corresponding to boundaries of the object to be imaged,generate a representation of each angular position for each detector unit position,generate a model based on the angular positions using the representation, anddetermine scan parameters to be used to image the object using the angular positional curves.
