    摘要： In a computerized method and apparatus to automatically determine an acquisition volume of an examination region for the acquisition of a magnetic resonance data set, at least one magnetic resonance image data set is acquired that at least partially images an examination region, and the magnetic resonance image data set is processed into at least one magnetic resonance image. The examination region is segmented and at least one envelope enclosing a segment is determined. At least one rectangle including the envelope is determined. The acquisition volume is calculated using the rectangle.

    摘要： In a method and control apparatus for tracking a contrast agent using an imaging medical device a test bolus of a contrast agent is initially injected into an examination subject, followed by an injection of a main bolus at a time interval of &Dgr;ti. The arrival of the test bolus in the observation volume is chronologically determined by periodically repeated survey measurements. An image data measurement is started at a time interval &Dgr;tm subsequent to the detection of the test bolus, this time interval &Dgr;tm being defined according to the prescribed time interval &Dgr;ti.

    摘要： A method and system for detecting lymph nodes in multiple complementary magnetic resonance (MR) sequences is disclosed. Anatomical landmarks, such as blood vessels, are extracted in a first MR sequence, such as an MR angiography (MRA) image. A search area is defined in at least one second MR sequence, such as a T1 weighted VIBE image, based on the anatomical landmarks extracted the first MR sequence. Lymph nodes are then detected in the search area of the second MR sequence. The lymph nodes can be detected by segmenting the search area into homogenous regions and determining whether each region is a lymph node using feature analysis.
