Abstract:
1. An apparatus for scanning control in a magnetic resonance scanning chamber, comprising: a magnetic resonance imaging system for scanning a patient and receiving echo signals; wherein the magnetic resonance imaging system comprises a magnet which is placed in a scanning chamber; a scanning chamber computer placed in the scanning chamber; and an operating chamber computer located in an operation chamber separated from the scanning chamber, wherein a communication connection is established between the operating chamber computer and the scanning chamber computer; wherein the scanning chamber computer sends a request to the operating chamber computer for initiating a positioning scan, performs a queue management operation on a scan protocol queue received from the operating chamber computer to manage a set of scan protocols selected for scanning, and displays images comprising a positioning image from the positioning scan; wherein the operating chamber computer selects a corresponding scan protocol comprising a localizer protocol, initiates the magnetic resonance imaging system to scan in response to the request from the scanning chamber computer, and reconstructs echo signals obtained from the positioning scan to obtain the positioning image; wherein the scanning chamber computer also performs a positioning operation during a general scan, wherein the positioning operation comprises selecting a receiving coil corresponding to an examination body part of a patient; wherein the positioning operation further comprises calculating a modified geometry parameter according to the positioning operation and sending a request to the operating chamber computer for modifying a geometry parameter displayed on the operating chamber computer so as to synchronously obtain the modified geometry parameter in the scanning chamber computer and the operating chamber computer; wherein the operating chamber computer initiates the magnetic resonance imaging system to scan according to the modified geometry parameter during the general scan.
