ABSTRACT:
An apparatus for irradiating a breast of a patient includes a radiation source, a structure adapted to hold a breast of a patient in receiving a radiation from the radiation source, and a vacuum source. The structure includes a member having an interior generally conformal to a shape of the patient's breast when the breast is uncompressed or pendulous. The vacuum source is adapted to provide a negative pressure in the interior of the member, whereby in use of the apparatus with the patient in a supine position, the breast is held in the generally uncompressed shape. A method of irradiating a breast of a patient includes the steps of placing a breast of a patient in a structure which includes a member having an interior generally conformal to a shape of the patient's breast when pendulous or uncompressed, applying a negative pressure in the interior, thereby bringing the breast in contact with the member in the generally uncompressed shape, and delivering a radiation beam to the breast of the patient in a supine position.
