Aspects of various examples described herein can include using a wearable ultrasound device (e.g., a device wearable or manipulated using a fingertip). The wearable ultrasound device can include an ultrasound transducer element array, and can have a housing providing circuitry to process signals to or from the array, such as digitizing such signals. For example, a channel count of the analog signal channels corresponding to individual sensors in the array can be converted to a single digital channel (e.g., a serial channel), or at least a reduced channel count as compared to a count of transducer elements. In this manner, a wired or wireless coupling between the ultrasound “front end” circuitry in the wearable device and processing or display hardware elsewhere need not accommodate a large number of analog channels, and can instead, for example, have a digital communication interface. |
