Ideas for this project began germinating more than twenty years ago when the artist was undergoing pelvic floor biofeedback therapy and was confronted with the immense gaps in medical research when it came to female anatomy. 

Twenty years later, having discovered a tumour in her left breast, she noticed a similarity between the ultrasound images of her breast and radar images of the surface of planet Venus. Christie started comparing her other medical images (Ultrasound, MRI, and X-Rays) with even more astronomical images (radio telescope images from the Arecibo Observatory in Puerto Rico and radar images from the Magellan spacecraft that orbited Venus from 1990-1994). She noticed that once identifying text was removed, sometimes it was difficult to tell which images were from the inside of her body, and which ones were from outer space. This similarity between the cosmic and the internal, the macro and the micro, continued to call to her.

Études corporelles, is a series of studies that morphs astronomical images of celestial bodies with medical images of her internal organs. Various research themes in this work include image making with sound waves and radio waves through ultrasound and radar, as well as the electromagnetic similarities between celestial bodies and humanly bodies.
