摘要： The invention relates to a method and apparatus for monitoring an object of interest (100). According to the invention, a cushion (104) is inflated such that the inflated cushion extends inwards to envelop the object of interest (100), whereupon the pressure exerted on the object of interest (100) by the inflated cushion (104) is measured and a signal is output to stop inflating when the pressure reaches a predefined threshold. After that, the volume of the inflated cushion is measured and the size of the object of interest (100) is derived from the volume of the inflated cushion (104). In this way, the invention can keep the object of interest still during monitoring. Furthermore, the size of the object of interest can be used for imaging reconstruction to improve the quality of reconstructed images.
