A training aid for teaching needle biopsy of the human breast. The inventive methods use breast models having lifelike properties providing accurate tactile sensation during palpation of the breast that enable a trainee to learn to locate modeled internal lesions and similar tissues in the breast. These same properties allow learning of tactile sensations indicating relative position and motion of biopsy needles during biopsy needling procedures. To facilitate tactile learning, the breast model includes an opaque skin that blocks the trainee view of a breast cavity containing modeled lesions, ensuring that needling procedures are performed based solely on "feel". The present invention also includes alternative training methods using a second breast model that is sufficiently transparent to allow viewing of modeled lesions from any relative position. The present invention includes training systems incorporating breast models and viewing stands and methods of training using these aids.

A remote palpation technique in breast imaging involves the use of multiple applications of radiation force in rapid succession throughout a two-dimensional plane in the target tissue medium (10), and combination of the small, two-dimensional displacement maps from each force location into a single, larger remote palpation image (block 43). Apparatus for carrying out the foregoing method is also disclosed.

A haptic sensor for performing palpation includes a deformable membrane having a reflective surface, a light source, a camera, and a processor. When the sensor is pressed against an object on a body, the deformable membrane deforms to contour to the shape of the object, light is reflected off the reflective surface, and captured by a camera. The reflected light is processed to reconstruct a 3-D image of the object. The rendered image can show abnormalities such as cysts, tumors, or other abnormalities, as well as arterial pressure pulses. In different embodiments, the sensor illuminates the deformed membrane from multiple directions, using shape-from-shading or grayscale mapping, or using video streams to provide more accurate images. The sensor is able to be included as part of a mobile device, such as a mobile phone, thereby making it compact and portable.
