Abstract: A de-convolution process is applied to an MR, CT or other image (25) of a scanned-object (23) to derive the point-spread function (22?) at an object-edge and to pin-point from the mid-point of its full-width-half-maximum FWHM, the location (30) of the true image-edge. With the object-image (25?) overlying the PSF function (22?) in the de-convolution space, sub-pixels which follow location (30) are transferred to before it to re-construct the image-edge (25?) for sharper conformity to the object-edge (23). Sharp definition of image-contour (37) facilitates accurate determination of area and volume of image profiles (35) and their segmentation. The accurate image-edge definition enables viable correction of geometrical distortion in stand-alone MR diagnosis and treatment planning.

Abstract: (A) This invention of the flexible, expandable, & retractable balloon (FERB) RF internal receiving coil is aimed at addressing the key areas of interest such as the enhancement of the MR image performance at the local areas/volume of the patient organs being studied, the provision of images beyond the tissue walls where the Endoscopy fails to provide, the designs of the shape and size of the balloon/RF coil insert to fit into the patient organs' contours and into a greater depth such as the intestines etc . . . the user friendliness and comfort, and, the meting the health and safety requirements. Whereas the existing internal RF coil designs fail to address either partly, or mostly. A rigid-rod cervix RF receiving coil and its disposable outer shell are also included into the invention.
