ABSTRACT:
A hand held ultrasound system is disclosed. By use of a curved reflector for focusing sound energy reflected by a structure being imaged a simple, lightweight, and power efficient device is presented. A transmitter directs a sound wave into a patients body, a structure to be imaged reflects some of the sound wave, a curved reflector focuses that sound energy onto one or more receivers. If more than one receiver is used they do not need to be phased since this function is performed by the curved reflector. The reflector may be spherically shaped or ellipsoidal. The device can function in either mono-static mode or bi-static mode depending on the depth of focus required, e.g., for imaging structures close to the skin surface (blood vessels and the like) an ellipsoidal shaped reflector is used since it provides a very short or close-up depth of focus. The device provides good resolution while using relatively little power making the device light in weight and small in size.
