摘要:
The imaging system can comprise a plurality of elongated rails, a scanhead assembly, and a small animal mount assembly. The scanhead assembly is selectively mounted onto a first rail and is constructed and arranged for movement in a linear bi-directional manner along the longitudinal axis of the first rail. The small-animal mount assembly is selectively mounted onto a second rail and is constructed and arranged for movement in a linear bi-directional manner along the longitudinal axis of the second rail. The second rail being mounted relative to the first rail such that the longitudinal axis of the second rail is at an angle to the longitudinal axis of the first rail. The small-animal mount assembly can include a table member suitable for mounting a small animal. The table member can be selectively positionable into a desired table plane. The imaging system can also comprise a needle injection assembly that is selectively mounted onto the third rail and is constructed and arranged for movement in a linear bi-directional manner along the longitudinal axis of the third rail. The third rail being mounted relative to the second rail and the first rail such that the longitudinal axis of the third rail is substantially coaxial to the longitudinal axis of the first rail.
摘要:
A method for producing an ultrasound image comprises monitoring the subject's respiration cycle or waveform, acquiring ultrasound data from the subject, producing an ultrasound image from the received ultrasound data received during the time when the subject's motion due to breathing had substantially stopped.
摘要:
A system for producing an ultrasound image comprises a scan head (106) having a transducer (124) capable of generating ultrasound energy at a frequency of at least 20 megahertz (MHz), and a processor (134) for receiving ultrasound energy and for generating an ultrasound image (116) at a frame rate of at least 15 frames per second (fps).
