Abstract: The invention relates to a brachytherapy apparatus (1) for applying a brachytherapy to a living object. The brachytherapy apparatus comprises a planning unit (14) for determining a placing plan defining placing positions and placing times for one or several radiation sources within the living object and close to a target region. The placing plan is determined such that the placing times are within a treatment time window determined by a treatment time window determination unit (13), wherein within the treatment time window a change of a spatial parameter of the living object caused by swelling is minimized. An adverse influence on the brachytherapy due to swelling can thereby be minimized, which improves the quality of the brachytherapy.

Abstract: An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.
