The long term objective of the proposed program is to develop Acoustography, a new imaging method, to aid in the detection and characterization of breast cancer. Acoustography uses ultrasound to produce full-field projection images of the breast in a manner which is analogous to x-ray mammography. An "acousto-optical" liquid crystal display, analogous to a fluoroscopic screen, is used to visualize and record the ultrasonic image of the entire breast. The specific aim in Phase I will be to use breast phantoms to evaluate Acoustography. Tissue mimicking materials currently used for producing phantoms to evaluate conventional ultrasonography equipment will be used to produce breast phantoms suitable for acoustographic studies. Commercially, Acoustography offers physicians a much more practical way of generating ultrasonic images because the entire breast can be imaged with only one or two images, and the image format allows direct side-by-side comparison of the ultrasonic and x-ray breast images. Compared to general-purpose scanners, Acoustography is more repeatable because the procedure can be standardized similarly to an x-ray mammography. Compared to dedicated scanners, Acoustography is cost-effective and offers high patient throughput; the entire breast information is available in seconds on 1 or 2 images, as opposed to 100-150 images in dedicated scanners.

拟议程序的长期目标是发展 声学是一种新成像方法，可帮助检测和 乳腺癌的表征。 声学使用超声波 以某种方式产生乳房的全场投影图像 类似于X射线乳房X线摄影。 “声学”液晶 显示，类似于荧光镜屏幕，用于可视化和 记录整个乳房的超声图像。 具体目标 第一阶段将使用乳房幻像来评估声学摄影。 组织 模仿目前用于生产幻影评估的材料 传统的超声检查设备将用于产生乳房 适用于声学研究的幻影。 在商业上，声学为医生提供了一种更实用的方式 产生超声图像，因为可以对整个乳房成像 只有一个或两个图像，图像格式允许直接并排 超声波和X射线乳房图像的比较。 相比 通用扫描仪，声学术更可重复，因为 手术可以类似于X射线乳房X线摄影。 比较的 对于专用的扫描仪，声学具有成本效益，并且提供高 患者吞吐量；整个乳房信息可在几秒钟内获得 在1或2张图像上，而不是专用扫描仪中的100-150张图像。
