The Astrasono A3Essential Scanner is B-mode pulsed-echo ultrasound device. It is intended as a handheld battery-operated device. The device projects ultrasound energy through the lower abdomen of the patient to obtain images of the bladder which is used to calculate bladder volume noninvasively. It is intended to be used only by qualified medical professionals.
An assembly of portable, battery-powered devices designed for the extracorporeal ultrasound measurement of the male or female urinary bladder volume. It typically consists of an electronic measuring and imaging display unit with a connected ultrasound transducer which together reproduce digitized data of the bladder, typically bladder volume and post-void residual (PVR), and images. It will generate ultrasound pulses, direct them to a the target area, detect the ultrasound echoes, and process the resulting information to produce and display static or dynamic three-dimensional (3-D) data/images. It is used in the diagnosis of urinary retention and postoperative urinary retention (POUR).
