ABSTRACT:
The invention relates to a system and a method for detecting an object of interest in a sequence of medical images. Said viewing system comprises alarm detection means (20) for detecting a set of alarms of said object of interest in a medical image (I′) at time t, in which an alarms is a set of data describing a possible location of the object. It further comprise temporal tracking means (30) for iteratively creating a set of tracks (T′) at time t by associating alarms of said set of alarms (A′) with tracks (T′1) at time t−1 and for choosing a track from among said set of tracks at time t in accordance with a merit criterion. Said track at time t is ended by an alarm which corresponds to a detection of said object of interest in said medical image at time t. Said viewing system advantageously accumulates temporal proofs for confirming or infirming spatial detections of alarms at time t. Detection of the object of interest is therefore made more robust to errors.
