Mri biopsy apparatus incorporating a sleeve and multi-function obturator
ActiveUS20050277829A1Facilitate invasive procedureEasy to confirmCannulasSurgical needlesBiopsy procedureBiopsy instruments
A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument, and in particular a sleeve, to a biopsy site of suspicious tissues or lesions. A depth stop enhances accurate insertion, and prevents over-insertion or inadvertent retraction of the sleeve. The sleeve receives a probe of the MRI-compatible biopsy instrument and may contain various features to enhance its imagability, to enhance vacuum and pressure assist therethrough, and marker deployment etc.

Mammographic apparatus, breast compression plate, and breast fixing method
ActiveUS20080080668A1Reduce assistancePrecise positioningRadiation diagnostic device controlPatient positioning for diagnosticsRadiologyBreast compression
A mammographic apparatus is set to take a medio-lateral oblique view (MLO) of a breast with an arm being tilted. After having positioned the breast on an image capturing base, the radiological technician moves a breast compression plate, which is tilted with respect to the image capturing base, toward the image capturing base. When the breast compression plate abuts against the breast and the breast is braced from below by the image capturing base, the radiological technician removes a hand from between the image capturing base and the breast compression plate, and then further moves the breast compression plate toward the image capturing base. A compression plate support mechanism turns the breast compression plate to make it substantial parallel to the image capturing base, thereby positioning the breast.

Methods and Apparatus For Performing Enhanced Ultrasound Diagnostic Breast Imaging
InactiveUS20080255452A1Ultrasonic/sonic/infrasonic diagnosticsInfrasonic diagnosticsProximateUltrasonic sensor
A method for performing enhanced ultrasound diagnostic breast imaging includes using first and second compression plates (62,64) configured for receiving and compressing a breast between the same. The breast extends from a chest wall (118) of a patient at a proximate end to a nipple at a distal end. Portions of the breast proximate the nipple and proximate lateral edges of the breast are in non-contact with the second compression plate during breast compression. An ultrasound transducer array (68) moves along a path to scan the breast, the ultrasound transducer array being disposed adjacent a side of the second plate (64) opposite the breast. Image data representative of the breast is acquired as the ultrasound transducer array (68) traverses the path. Acquiring image data includes using electronic beam steering with the ultrasound transducer array to acquire image data in either or both (i) a portion (116) of the breast proximate the chest wall and (ii) a portion of the breast in non-contact with the second plate (122).

A method and apparatus that increases safety when employing externally focused adaptive phased array microwave thermotherapy (hyperthermia) for breast cancer treatment include microwave absorbing pads and metallic shielding to prevent undesired or stray surface tissue heating and to cushion the breast from mechanical pressure during breast compression. The microwave absorbing pads are attached on the top of the microwave waveguide thermotherapy applicators and on top of the breast compression paddles. A metallic-shielding strip mounted across the top portion of the microwave applicator aperture acts to block microwave radiation from illuminating the base of the breast and chest wall area. The patient treatment table utilizes a metallic shield to shield the body from stray microwave radiation. Treatments incorporating the safety improvements include thermotherapy for early-stage breast carcinomas, locally advanced breast cancer, ductal carcinoma in-situ, and benign breast lesions.
