摘要:
1. System (1) obtaining magnetic resonance images comprising: at least one radio frequency (RF) transmitter coil (6), transmitting the measured RF-power to excite and manipulate magnetic resonance in the subjects tissue (57) in the study RF -peredatchik (34) controlling the amount of the transmitted RF-power, based on the specific absorption Rate (SAR) for receiving the sequence of images anthropometric block (28) defining a mass subject part that receives transmitted RF-power based n total weight of the subject a band-(40) adaptive SAR (40) regulating the selected scan sequence based on the SAR for the actual, not the worst case determined from the measured transmitted RF-power and the measured reflected power, and weight of the subject part, receives the transmitted RF-moschnost.2 . System (1) according to claim 1, further comprising: a block (38) reconstruction rekonstruiruiruyuschy image based on the reference scan and determining the position and orientation of the subject based on the existing reference points, wherein the anthropometric unit (28) defines a part of the subject. receiving the transmitted RF-power, based on the position and orientation of the subject and the characteristics of the at least one transmission coil (6) .3. System (1) according to Claim. 1, wherein the anthropometric unit (28) constructs a three-dimensional model (4) of the subject based on at least one characteristic of the subject, and determines the weight of the part of the subject, receiving the transmitted power based on the model (4). 4. System (1) according to Claim. 1, wherein the anthropometric unit (28) determines the total weight of the subject based on the measured weight, and checked by1. Система (1) получения магнитно-резонансного изображения, содержащая:по меньшей мере одну радиочастотную (RF) передающую катушку (6), передающую измеренную RF-мощность для возбуждения и манипулирования магнитным резонансом в тканях субъекта (57) в области исследованияRF-передатчик (34),
