摘要： Techniques are described that allow intravascular ultrasound (“IVUS”) imaging of patient tissue, e.g., a blood vessel wall, to be performed at one or more angles selected by a clinician, for example. In one example, a method includes receiving user input, via interaction with a user interface, that defines a range of angles through which a scan will be performed, determining, based on the received user input, at least one current value to be applied to at least one lead of a stator of a motor, controlling application of the at least one current to the at least one lead of the stator in order to rotate a rotor of the motor through the range of angles, and through the range of angles, receiving and processing electrical signals from at least one transducer to form at least one image.
