An automatic, stand-alone, hand-held ultrasound blood-vessel examination device () requires a reduced number of transducer elements () and presents a simplified user interface (-), without the need for displaying an image of any of the vessels. The probe, in one embodiment, acquires and examines a volume of interest (), searches for a target vessel, tests the vessel for normality of blood flow, and reports the diagnosis, all automatically and without need for user intervention. In another embodiment, the probe finds a body vessel (-) in a volume, and extracts a clinical Doppler parameter, all automatically and without need for user intervention. 1. An ultrasound device configured for carrying out a series of acts , said series comprising:a) examining, using an ultrasound probe of the ultrasound device, a volume to find body vessels present within the volume; and, 'wherein said acts of examining and selecting (i) do not rely on a display of ultrasound scan images, and (ii) are performed automatically and without need for user intervention to interpret an ultrasound scan image.', 'b) if one or more vessels are found within the volume in said examining, then b1) selecting, for fluid-flow analysis, a vessel from among said vessels found within the volume, b2) generating, for said fluid-flow analysis, information particular to the selected vessel, b3) determining, based on the generated information, whether said selected vessel matches a target vessel, and b4) if the selected vessel matches the target vessel, then b4) (i) providing, based on the generated information, an indication as to normality of fluid flow in the selected vessel, else b4) (ii) repeating the selecting, generating, and determining with a next vessel of the vessels found, until there is no further next vessel of the vessels found within the volume,'}2. (canceled)3. The ultrasound device of claim 1 , wherein the generated information comprises a quantitative characteristic of a waveform claim 1 , ...
