Problems solved by technology

Despite its widespread use as a diagnostic tool, mammography suffers from several limitations that affect its usefulness as a diagnostic tool for accurately detecting the presence of potential cancerous lesions
For example, in some groups of women, the sensitivity of mammography can be as low as 30-40%

Embodiment Construction

[0050] Embodiments of the invention relate to cone beam computed tomography (CBCT) systems. CBCT offers many improvements over prior art methods, including allowing earlier detection of smaller lesions than is possible with existing methods and devices. When a lesion is detected, a biopsy procedure can be used to sample tissue in order to characterize whether a tumor is present and, more specifically, whether the tumor appears to be metastatic. Percutaneous large gauge needle core biospy (NCB) is an accepted alternative to surgical biopsy in some settings. Methods and systems for lesion detection and biopsy with a CBCT system are described herein.

Abstract

Disclosed are embodiments of methods of and systems for detecting and biopsying lesions with a cone beam computed tomography (CBCT) system. The system comprises, in some embodiments, a CBCT device configured to output a cone beam CT image of at least a portion of a patient's breast and a multi-axis transport module, having at least three degrees of freedom and configured to position a biopsy needle within a 3D frame of reference based on inputs received from the cone beam CT device. The transport module can be configured to place the biopsy needle adjacent to, or within, a target of interest within the breast. Also disclosed are embodiments of methods of and systems for testing CBCT systems with phantoms.

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 61 / 016,030, filed December 21, 2007, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments of the invention relate to devices and methods for use in breast biopsy procedures and other breast cancer treatment procedures guided by cone beam CT imaging. Background technique [0004] According to the National Cancer Institute, one in eight women will be diagnosed with breast cancer during their lifetime. Additionally, although recent trends point to a decline in breast morbidity, nearly 40,000 women still die from the disease each year. [0005] The causes of breast cancer are diverse, and as such there is no single etiological factor, making it difficult to develop successful therapies. Thus, while attempts have been made to understand the basic biological processes involved in the development of the disease, and to possibly ...
