摘要
The present invention relates to an apparatus (2) and method (100) for determining at least one final two-dimensional image or slice that visualizes an object of interest in a three-dimensional ultrasound volume. A method (100) for determining at least one final two-dimensional image, the method comprising the steps of: (a) providing a three-dimensional image of a body region of a patient's body (101), the method comprising: An applicator configured to immobilize is inserted into the body region; and b) providing an initial orientation (102), in particular randomly determining the initial orientation in the three-dimensional image, And c) the following sequence of steps s1) to s4): s1) The set direction in the three-dimensional image is determined by the processing unit based on the initial direction of the first sequence or during the previous sequence. Determining step 104, s2) based on the probability map, the processing unit extracts an image set of two-dimensional images from the three-dimensional image. As a result, the two-dimensional images of the image set are arranged coaxially and subsequently to the set direction, step (105), s3) by the processing unit the applicator pretraining classification method to the image. Applying (106) to each of the two-dimensional images of the set, for each of the two-dimensional images of the image set, a cross-sectional view of the applicator in each of the two-dimensional images of the image set. Generating a probability score indicating the probability of being drawn, in particular completely drawn, s4) determining, by the processing unit, a probability map representing the probability score of the two-dimensional images of the image set with respect to the set orientation. Step (103) of repeating the step (107) of performing After completion of the scan, including two-dimensional image associated with the highest probability score, in particular image set that is determined during the last sequence, the step (108) for determining as the final two-dimensional image. The present invention provides an efficient scanning plane with an object of interest, eg an applicator (6), within the three-dimensional ultrasound volume to ensure that the ultrasound volume has the required clinical information. To provide a simple method.
