摘要： An ultrasound imaging system includes a biplane ultrasound probe and a console. The biplane ultrasound probe includes a sagittal array and a transverse array. The console includes a transmit circuit, a receive circuit, and an image generator. The transmit circuit is configured to control the sagittal and transverse arrays to emit ultrasound signals while the probe is manually rotated and translated. The receive circuit is configured to receive electrical signal produced by the sagittal and transverse arrays in response to the sagittal and transverse arrays receiving echoes produced in response to the corresponding ultrasound signals interreacting with structure. The image generator is configured to construct a three-dimensional image with the electrical signals from the sagittal or transverse array using the electrical signals from both the sagittal and transverse arrays to track the motion of the probe and align scanplanes.

摘要： A 3-D endocavity ultrasound probe includes an instrument holder having a channel configured to guide an instrument. The 3-D endocavity ultrasound probe further includes an elongate shaft with a center line, a first side, a second opposing side with a recess configured to receive the instrument holder over the center line, and a drive system disposed in the first side and not over the center line. The 3-D endocavity ultrasound probe further includes a probe head disposed at an end of the shaft. The probe head includes a rotatable support and a transducer array coupled to the rotatable support. The drive system is configured to rotate the rotatable transducer array support thereby rotating the transducer array. The channel extends along the center line thereby providing an instrument path in-plane with a sagittal plane of the elongate shaft.
