    摘要: In a method and magnetic resonance apparatus to assist a person in the alignment of a medical instrument used by the person to conduct a minimally invasive procedure with the instrument introduced into a patient at an entrance point in a predetermined orientation, within the patient receptacle of a magnetic resonance device, measurement data are acquired with the magnetic resonance device to determine a current orientation of the instrument and/or an instrument guide, and the measurement data are evaluated to determine the current orientation. A deviation of the current orientation from the predetermined orientation is determined, and at least one acoustic signal is emitted depending on the deviation to assist the person in orienting the instrument.

    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.
