Traction-inducing compression assembly for enhanced tissue imaging

摘要

Apparatus and methods are provided for compressing biological tissue for use with a radiographic or sonographic imaging system that enhances imaging of the tissue near a patient's chest wall. The apparatus includes a compression assembly having first and second compression surfaces, and structure for positioning the first compression surface relative to the second compression surface so that the first and second compression surfaces experience a lateral translation as they move towards one another. In addition the first and second compression surfaces may be tilted slightly relative to a plane orthogonal to the patient's chest wall to enhance the traction effect and to provide partial imaging within the patient's chest wall.
