Abstract

An ultrasonic imaging system is described which visually assists biopsy needle insertion. The system produces pixel values of pixels along one or more paths of needle insertion. A tissue density analyzer is responsive to the pixel values to estimate tissue density along a path of needle insertion. A needle path calculator is responsive to the tissue density analyzer and proposes one or more favorable paths through imaged tissue for insertion of the biopsy needle. The system may be used in conjunction with a three dimensional navigation system which spatially locates the needle and ultrasound image plane in 3D space.

Description

technical field

[0001] The present invention relates to medical diagnostic imaging systems, and more particularly to diagnostic ultrasound systems that provide visual guidance of needles during biopsies or other invasive procedures. Background technique

[0002] A biopsy is a medical procedure that involves the removal of cells or tissue for examination. The procedure involves the medical removal of tissue from a living subject to determine the presence or extent of disease. The resected tissue is typically examined under a microscope by a pathologist, and can also be analyzed chemically for the disease state. When the entire mass or suspicious area is removed, the procedure is called an excisional biopsy. When only a sample of tissue is removed, while preserving the histological architecture of the tissue's cells, the procedure is called an incision biopsy or core biopsy. When a needle is used to remove a sample of tissue or fluid in such a way that the cells are excised...
