Abstract: A camera housing/lens system comprises a camera housing for a camera and a lens. The camera housing/lens system further comprises a lock for locking the lens in position. The lock includes a stop member joined to the lens or the lens mount, and an elastic element arranged between the stop member and the lens mount or between the stop member and the lens, wherein the elastic element is compressed between the stop member and the lens mount or between the stop member and the lens to lock the lens in position. A gap remains between the stop member and the lens mount or between the stop member and the lens. This “elastic compression” allows the position of the lens to be finely adjusted in relation to the lens mount, without having to release the compression in order to do so.

The images are generally acquired using a pulse sequence that is designed to reduce physiological motion-induced artifacts and to mitigate chemical-shift artifacts from water-fat boundaries. Advantageously, the MRI technique described here suppresses chemical-shift artifacts without significantly reducing the signal intensity from fatty tissues, and thereby allows for more reliable visualization of vascular calcifications.

The mechanism which allows the lens cover to be secured to and removed from the camera includes a set of wires embedded into the lens cover and a set of wedges protruding from the lens wall of the camera. To secure the lens cover to the camera, the lens cover is placed onto the front of the camera and rotated until the wires align with corresponding wedges, securing the wires underneath the tapered surface of the wedges. To remove the lens cover from the camera, a force is applied outward and normal to the lens cover, causing the wires to flex outward and enabling the rotation and removal of the lens cover from the camera.
