Abstract
An indicator element of a percutaneous needle guide for a medical scanning device includes a pointer for pointing to a percutaneous needle entry site on an epidermis of a body, when the guide is attached to the device and the device is positioned over the epidermis for scanning. A user may orient and insert a needle into the entry site according to the direction of the pointer, by just viewing the pointer, without the needle being constrained by the pointer. The guide may include an adjustment mechanism for moving the indicator element with respect to the device, when the guide is attached to the device; the adjustment mechanism moves the indicator element, without changing an orientation of the pointer, in a direction approximately parallel to a plane that is approximately tangent with an apex of the device transducer surface and approximately perpendicular to a longitudinal axis of the device.
