Embodiment Construction

[0015] see now figure 2 , the intracavity ultrasound probe 30 of the present invention is shown. The probe head 30 includes a handle portion 36 by means of which the user holds the handle for operation during use. At the rear of the handle is a cable riser 18 for the probe cable (not shown). Extending from the front end of the handle 36 is the shaft 32 of the probe head, which terminates in a distal dome-shaped acoustic window 34 through which ultrasound waves are transmitted or received during imaging. Contained in the end of the shaft is a transducer mount assembly 40, which is also shown in the cross-sectional view of the shaft in FIG. 3 and Figure 4 In the uncovered view in . A convexly curved array transducer 46 is attached to a transducer mount 48 at the end of assembly 40 . The transducer mount 48 is pivotally mounted by its pivot axis 49 to rock back and forth at the end of the probe so that the image plane sweeps across the volumetric region in front of the prob...

Abstract

An intracavity ultrasound probe includes a pivotally mounted array transducer which is oscillated to scan a volumetric region from within the body. The transducer is oscillated by a motor located in the probe handle. The array transducer is immersed in a liquid which acoustically couples ultrasonic energy between the elements of the transducer and the body. The acoustic coupling liquid is located in the distal tip of the probe shaft, where only 6 cc of liquid is required. The small amount of liquid reduces the weight of the shaft of the probe so that the center of gravity of the probe is in the handle, making the probe comfortable and easy to manipulate. The majority of parts in the probe shaft are made of aluminum or other low density materials, keeping the overall weight of the probe to about 250 grams.

Description

technical field [0001] The invention relates to a medical diagnostic imaging system, in particular to an intracavity probe used in an ultrasonic diagnostic imaging system for three-dimensional imaging. Background technique [0002] Intracavity ultrasound probes have been used for many years to image the human body from inside the body. Imaging from inside human viscera allows for more direct imaging without transmitting ultrasound waves through intermediate tissues and structures. For example, a transesophageal probe can image the heart and abdominal organs from the esophagus or stomach, eliminating the need to send and receive ultrasound waves through or around the ribs. The present invention relates to intraluminal probes inserted in the vagina (IVT probes) or rectum (ICT probes) to image the cervix, uterus or prostate. [0003] In the past, IVT and ICT probes have been able to scan two-dimensional image areas from inside the human body. This can be achieved with an arr...
