A new, inexpensive and non-invasive fetal visualization process helps to locate fetal body parts and identify fetal positions without exposing the fetus to prolonged ultrasound irradiation. Associating location data with biological electrophysiology signal patterns and/or light absorption/reflection-related tissue-specific local fetal body composition data enables the generation of a 3D anatomical and functional map of the fetal body through the expecting mother's womb, which will be essential for long-term home monitoring of a fetus during pregnancy.

The invention relates to a method for positioning three axial positions of a fetal brain through magnetic resonance. The method is used for further rapidly, accurately and normatively positioning an image of the three axial positions of the fetal brain on the basis of the traditional nuclear magnetic resonance scanning and positioning technology and providing a more accurate and normative cross-section image for clinical medicine. Because the position and the direction of a fetus in a parent are possibly changed at any time, the standard three axial positions of only a few fetuses can be directly positioned through the standard three axial positions of the parent; in many cases, the position of the fetus in the parent is changeable; the standard image of the three axial positions cannot be obtained through the traditional technology; when the standard three axial positions of the parent cannot be given or the standard three axial positions of the fetus cannot be better given, a series of images of various positions can be obtained by rotating and positioning in 360 DEG through a haste sequence, namely a heavy T2 weighted line; and the image closest to the standard fetal position is selected from the series of images and served as the standard to position the brain.

A device is disclosed that provides for relaxation and back stretching. In particular, the device allows the user to assume a position similar to the prone fetal position, often referred to as the “balasana” or “child's pose” in yoga. The device provides additional advantages over traditional ways of assuming the “child's pose” by providing support for the user's body which relieves the stress caused at the point of contact between the floor and the user's feet, knees and ankles. A cavity is disposed for accommodating the user's face, allowing for comfortable breathing. Further, the facial cavity supports the user's head in such a way as to align the spine while stretching. The device of the invention utilizes gravity to enhance the stretch of the user's back and spine over the traditional “child's pose” without placing the user of the device in an unnatural or uncomfortable position. The device folds into an aesthetically pleasing cube for easy storage or for use as a support surface for sitting or as a table.
