Abstract: A breast imaging system is described which includes compression plates for retaining a breast during an examination. One of compression plates is formed by a polymeric membrane stretched under tension to provide a rigid but compliant retention surface which is substantially acoustically transparent for the conduct of a sonographic examination. The polymeric membrane may also be substantially radiographically transparent for the conduct of a mammographic examination. The thickness of the membrane is chosen to be a function of one-half of the wavelength of the ultrasonic frequency used for the sonographic examination so as to be substantially transparent to ultrasonic energy at that frequency.

Abstract: An accessory is disclosed herein for use during exercise including a layer of towel material having opposite tufted surfaces. One surface is employed for carrying a pocket having a closable end for insertably receiving personal items such as keys, money, etc. A magnetic anchor is carried on the edge marginal region of the towel midway between its opposite ends for releasably attachment to ferro-magnetic material intended to support the towel, such as an exercise stand, platform support or the like.

Abstract: An elongated platform is disclosed herein for supporting a person in a chair or recliner which is adapted to rotate about a central pivot support and having wheels arranged in an arc adjacent to the opposite ends of the platform. The exposed upper surface is provided with a pair of spaced apart grooves or recesses for insertably receiving the standard rungs of the chair or recliner. Snap-lock latches releasably retain the rungs in position so that the chair or recliner and the platform constitute a unitary structure.
