Hologic corporation is a developer, manufacturer and supplier of diagnostic and medical imaging systems related to women's health. It develops digital imaging technology for general radiography and mammography applications. Its core business units are focused on osteoporosis assessment, gynecologic health, mammography and breast biopsy, direct-to-digital x-ray for general radiography applications and mini C-arm imaging for orthopedic applications. Its major brands include Lorad, Fluoroscan, NovaSure, MyoSure, Selenia, Securview, Discovery, Multicare and Directray.Hologic is a leader in women's healthcare, particularly breast cancer diagnosis.Hologic is currently developing tomosynthesis technology for breast cancer diagnosis. Hologic first demonstrated the technology at the Radiological Society of North America in November 2003. It provided patient images and a prototype add-on to its Selenia digital mammography system. Clinical trials for Hologic's tomosynthesis technology began in the summer of 2004.Hologic was the recipient of Frost and Sullivan's 2004 Technology Leadership of the Year Award in women's healthcare.

A slidable locking device for fixing a position of a medical device, includes a housing having a passageway therethrough and an actuator coupled to the housing movable between a locked position and an unlocked position. The actuator includes at least two arms extending therefrom that are operatively coupled with at least two engaging members disposed within the housing, each engaging member having a slot configured to receive a respective arm of the actuator, the engaging members being biased towards the housing passageway, wherein the engaging members are disposed toward the housing passageway when the actuator is in the locked position, and the engaging members are disposed away from the housing passageway when the actuator is in the unlocked position.

A method for use in medical imaging of a patient including, with the patient immobilized with respect to an imaging reference frame, acquiring first digital imaging information including a first region of interest using a first imaging modality; processing the first digital imaging information to identify a feature for analysis; and using a second imaging modality to acquire targeted second imaging information for a second region of interest, the second region of interest corresponding to a subset of the first region of interest, wherein the second region of interest includes the feature for analysis. An apparatus for use in medical imaging comprising structure for immobilizing a patient with respect to an imaging reference frame; a first imaging system for acquiring first digital imaging information including a first region of interest using a first imaging modality; a processor processing the first digital imaging information using a diagnostic tool to identify a feature of interest; and a second imaging system for acquiring second imaging information using a second imaging modality, the second imaging information corresponding to a second region of interest including the feature for analysis.

A multi-mode system and method for imaging a patients breast with x-rays in one or more of a CT mode, a narrow-angle tomosynthesis mode, a wide angle tomosynthesis mode, and a mammography mode, using essentially the same equipment, on one or more compressions or immobilizations of the breast.

Systems and methods for automatically and dynamically modifying an image acquisition parameter for use in tomosynthesis breast imaging. A selected image acquisition parameter is modified in response to a measured characteristic of an imaged object such as a breast, and thus tailored to provide the highest quality image for the particular object. For example, image quality in a breast tomosynthesis system can be improved by dynamically varying motion and other acquisition parameters of the tomosynthesis system in response to physical characteristics of the breast to be imaged (determined during image acquisition), such as the breast thickness, density or composition. Dynamically varying acquisition or processing methods helps to customize the system for each particular patient, thereby improving image quality and identification and assessment of potential pathologies and abnormalities, and lower radiation dose, and thus a reduced the risk of long-term adverse health effects due to lifetime accumulated radiation dose.

A uterine fibroid tissue removal device includes an inner tube disposed within an outer tube and configured to be translated and rotated relative to the outer tube, and a separately formed unitary distal tip member attached to a distal end of the inner tube, such that the distal tip member translates and rotates relative to the outer tube along with the inner tube, wherein a distal facing open cutting end of the distal tip member in fluid communication with an axial lumen of the distal tip member translates across a tissue resection window in a sidewall of the outer tube so as to sever tissue extending therethrough, the distal tip member axial lumen being in fluid communication with an axial lumen of the inner tube, wherein an outer diameter of the distal tip member is greater than an outer diameter of the inner tube.

The disclosure describes devices and methods for asymmetrical irradiation at a body cavity or site, such as after removal of tissue, e.g. biopsy or cancer. One device includes a lumen which is off-set or off-settable from a longitudinal axis to increase the intensity of radiation received from a radiation source by a first tissue portion surrounding the body cavity and to reduce or minimize radiation received by a second tissue portion (e.g. healthy tissue) surrounding the body cavity.

Disclosed is a tissue removal device. The device includes an outer tubular body, an inner tubular body and a cutting edge on the inner tubular body. The outer tubular body includes a window, which may be opened or closed by moving the cutting edge. The cutting edge has a hardness that exceeds the hardness of the material of the inner tube. The cutting edge may have a Rockwell C hardness of at least about 50, while the inner tube has a Rockwell C hardness of no more than about 40. The cutting edge may be formed by a milling step, and the inner tube may be formed by a drawing step. Tissue severed by the cutting edge may be removed at a rate of at least about 1.8 grams per minute through the inner tube, and the outer tubular body may have an outside diameter of no more than about 3.5 mm.

A biopsy system driver includes a motor having a rotatable output shaft, a support structure, a drive shaft, an elongate lead screw and a biopsy instrument drive member. The drive shaft is rotatably coupled to the support structure and includes or is otherwise operatively connected to the motor output shaft such that activation of the motor rotates the drive shaft. The elongate lead screw is coupled to the drive shaft such that rotation of the drive shaft rotates the lead screw about an axis of the lead screw. The lead screw is axially translatable relative to the drive shaft and to the support structure. The biopsy instrument drive member is threadably coupled to the lead screw such that rotation of the lead screw causes axial translation of one of the lead screw and biopsy instrument drive member relative to the other one and to the support structure.

A guide member facilitates a device swap for brachytherapy treatment. A cavity evaluation device is introduced during surgery such that a distal end of the device is disposed in a resected cavity of the patient. The cavity evaluation device includes a shaft in which is disposed an elongated guide member. In a subsequent out-patient procedure the cavity evaluation device is removed from the resected cavity. If a brachytherapy treatment is to be performed then the cavity evaluation device is removed without removing the elongated guide member such that position of a portion of the elongated guide member in the resected cavity is maintained relative to the resected cavity. An anchor member helps to maintain the position of the guide member. Introduction of a brachytherapy catheter is then facilitated by introducing the elongated guide member into an opening of the brachytherapy catheter and using the elongated guide member to guide the brachytherapy catheter to the resected cavity.
