Abstract: A tabletop useful for accurate positioning of a patient for imaging and diagnosis, so that patient positioning in subsequent medical treatments, such as radiation therapy, accurately and precisely correlates with the imaging data. The tabletop of the present invention is a solid flat tabletop adapted to fit over or as an insert in a conventional CT imaging or scan table and provides a flexible support section in which the flexible support material is tensioned to provide a vertical deflection corresponding to the vertical deflection of a flexible patient support of a treatment simulator or linear accelerator. In a preferred embodiment, the flexible support section may be removed and inserted into the treatment table to provide an exact correlation in vertical deflection during treatment.

Abstract: Graduated catheters including, but not limited to, graduated urethral and ureteric catheters are provided, the catheters each comprising a catheter tube, an expandable portion, and at least one indicator. The position of at least one indicator may be determined by an extracorporeal imaging method. A kit comprising a matched pair of graduated catheters is also provided, wherein the position within a bodily lumen of a subject of at least one indicator of a graduated locator catheter of the kit has a known relationship to the position within the bodily lumen of at least one indicator of a graduated delivery catheter of the kit. Brachytherapy methods are also provided, including methods of treating urethral and ureteric strictures, prostate cancer, and benign prostatic hypertrophy.
