Abstract
A slide lock device is provided for releasably locking a patient positioning mold to a base for accurate and repeatable radiation therapy. The slide lock device includes a rail secured to the base and a tab slidably mounted on the rail for overlapping engagement with the frame of the patient positioning mold. The tab locks the mold against vertical and lateral movement relative to the base in a quick and easy manner. A plurality of holes in the rail allow adjustable positioning of the mold through the use of indexing pins.

In combination, a base, a radiation therapy patient positioning mold having a frame with an index pin including a downwardly extending leg and an upwardly disposed head, and a device for locking the mold to the base, the device comprising:
- a rail secured to the base and having a plurality of holes therein for receiving the leg of the indexing pin;
- a tab slidably mounted to the rail and having a retainer spaced upwardly from the rail to define a space for receiving the frame of the mold sandwiched between the retainer and the rail;
- the tab being slidable along the rail so as to overlappingly engage the frame of the mold and thereby lock the mold in place on the base.
A slide lock device for releasably locking a frame to a base, the frame having an indexing pin with a downwardly extending leg and an upwardly disposed head, the device comprising:
- a rail for attachment to the base and having a plurality of holes for receiving the leg of the indexing pin;
- a slide tab slidably mounted on the rail for longitudinal movement with respect thereto and having a retainer extending therefrom in spaced relation to the rail for sandwiching the frame between the retainer and the rail and thereby locking the frame to the base.
A method for releasably locking a radiation therapy patient positioning mold to a base for accurate repeatable radiation therapy of a patient, the method comprising:
- positioning a patient on the base;
- placing the mold over the patient's body;
- inserting indexing pins on the mold into corresponding holes in a plurality of rails on the base;
- sliding a tab along each rail into overlapping engagement with the mold so as to lock the mold against upward movement relative to the base.
