摘要：
1. Brachytherapy System, soderzhaschaya- at least one miniature X-ray source (10) suitable for placement in the catheter (68) for brachytherapy, having at least one anode (12) and at least one cathode (14), wherein in operation the electric field (18) between the anode (12) and the cathode (14) is substantially spherically symmetric at least in a continuous solid angle of more than π / 2 sr around the center (16) of the cathode (14), brachytherapy system further comprising MR-scanner operable to control the position and / or the direction of the X-ray source (10) at least by means of MR-images, and at least one block (84) control for controlling the operation of at least one of a miniature X-ray source (10) .2. Brachytherapy System according to Claim. 1, wherein the continuous solid angle in which the electric field (18) is substantially spherically symmetric, more than 2π cf., around the center (16) of the cathode (14) .3. Brachytherapy System according to Claim. 1, wherein the anode (12) substantially completely covers the cathode (14) .4. Brachytherapy System according to Claim. 1, wherein the anode (12) formed by a first sphere having a radius of 5 mm and a cathode formed of the second sphere having a radius of 1 mm.5. Brachytherapy System according to Claim. 1, wherein the anode (12) comprises at least two anode elements (54, 56) which are operable to form an anode (12) and wherein one element (56) of the at least two elements (54, 56) of the anode (12) is electrically isolated from the rest of the anode (12) and electrically insulated member (56) of the anode (12) includes a continuous solid angle greater than 4π / 3 cp, around the center (16) of the cathode (14 .6). brachytherapy system1.
