Implementations described and claimed herein provide systems and methods for securing a device for acquiring cardiac data points from a patient. In one implementation, the device includes a patient interface and a probe. The patient interface includes an anchor having a patient side adapted for attaching to a surface of the patient and a probe side disposed opposite the patient side. The patient interface further includes a synchronizer having a plurality of synchronization features corresponding to a plurality of imaging locations on the patient. The synchronizer is mounted to the anchor and adapted to engage the probe. A window extends through the anchor and the synchronizer. The plurality of synchronization features are positioned around the window. Each of the synchronization features includes a unique set of keys identifying one of the plurality of imaging locations.
