Embodiment Construction

[0032] refer to figure 1, the mammography apparatus of the present invention is denoted by reference numeral 1 . The mammography system 1 is used to screen the breast 2 for malignant cells 8 . For this purpose, the mammography apparatus 1 comprises an X-ray source 3 and an X-ray detector 4 cooperating with the X-ray source for providing an X-ray image of said breast 2 .

[0033] The mammography apparatus 1 also comprises a paddle 5 for flattening the breast by pressing the breast 2 against said X-ray detector 4 . In the embodiment shown, the paddle 5 is provided with a force or torque sensor 20 to measure the force with which the paddle 5 flattens the breast 2 . Also included is a control system 10, typically forming part of a computer system 19, which is provided for receiving a measurement signal from a force or torque sensor 20 via line 11, and using the result of the contact area measurement ( discussed in the next paragraph) to control the actuation of paddle 5.

Abstract

Mammography-apparatus for detecting malignant cells in a breast comprising an x-ray source and an x-ray detector that cooperates with the x-ray source for providing an x-ray image of said breast, and further comprising a paddle for flattening the breast by pressing it against said x-ray detector, wherein at least one sensor is applied for measuring a parameter that is used for determining the pressure at which the paddle compresses the breast, and wherein a control system is provided which controls the actuation of the paddle depending on the pressure that is applied to the breast, wherein there is a contact area measuring unit for measuring the contact area between the breast and the paddle.

Description

technical field [0001] The present invention relates to a mammographic apparatus for detecting malignant cells in a breast, comprising an X-ray source and an X-ray detector cooperating with the X-ray source to provide an X-ray image of said breast, further comprising A paddle that presses against said x-ray detector to flatten the breast, wherein at least one sensor is employed to measure a parameter for determining the pressure with which the paddle is pressed against the breast, and wherein control of the paddle is provided in accordance with the pressure exerted on the breast actuation control system. Pressing the breast with a paddle against the x-ray detector for the purpose of flattening the breast is desirable for obtaining a proper x-ray image of the breast. Background technique [0002] A mammography apparatus as described in the preamble is known from US-B-7,656,993. In this known mammography apparatus, the paddle is shaped according to the curve of the breast an...
