An apparatus for providing guidance to a user of an ultrasound acquisition system to acquire a target view of a target anatomical structure of a patient, the apparatus comprising: a receiving unit adapted to receive an ultrasound image acquired by the user with an ultrasound acquisition system; a processing unit comprising: a view analyzer module adapted to determine a spatial relationship between the received ultrasound image and a target view, and compute at least one distance metric for the acquired ultrasound image based on said spatial relationship, and a guidance module adapted to generate guidance information based on said spatial relationship, indicative of a change in position and/or orientation of the ultrasound acquisition system for the acquisition of another ultrasound image; and an input/output adapted to operably couple the processing unit with a user interface, wherein the processing unit is adapted in use to selectively toggle the user interface, between: a guidance mode in which guidance information generated by the guidance module is provided on the user interface and the received ultrasound image is not provided on the user interface; and an imaging mode in which the received ultrasound image is provided on the user interface; and wherein the processing unit is adapted to set the user interface to the guidance mode if the at least one distance metric exceeds a predefined threshold, and set the user interface to imaging mode otherwise. a receiving unit adapted to receive an ultrasound image acquired by the user with an ultrasound acquisition system; a processing unit comprising: a view analyzer module adapted to determine a spatial relationship between the received ultrasound image and a target view, and compute at least one distance metric for the acquired ultrasound image based on said spatial relationship, and a guidance module adapted to generate guidance information based on said spatial relationship, indicative of a change in position and/or orientation of the ultrasound acquisition system for the acquisition of another ultrasound image; and a view analyzer module adapted to determine a spatial relationship between the received ultrasound image and a target view, and compute at least one distance metric for the acquired ultrasound image based on said spatial relationship, and a guidance module adapted to generate guidance information based on said spatial relationship, indicative of a change in position and/or orientation of the ultrasound acquisition system for the acquisition of another ultrasound image; and an input/output adapted to operably couple the processing unit with a user interface, wherein the processing unit is adapted in use to selectively toggle the user interface, between: a guidance mode in which guidance information generated by the guidance module is provided on the user interface and the received ultrasound image is not provided on the user interface; and an imaging mode in which the received ultrasound image is provided on the user interface; and wherein the processing unit is adapted to set the user interface to the guidance mode if the at least one distance metric exceeds a predefined threshold, and set the user interface to imaging mode otherwise. a guidance mode in which guidance information generated by the guidance module is provided on the user interface and the received ultrasound image is not provided on the user interface; and an imaging mode in which the received ultrasound image is provided on the user interface; and wherein the processing unit is adapted to set the user interface to the guidance mode if the at least one distance metric exceeds a predefined threshold, and set the user interface to imaging mode otherwise.
