[ detailed description ] embodiments
Referring to fig. 1, fig. 1 illustrates the major components of a magnetic resonance system 10 incorporating the present invention, which is controlled by an operator console 12, the console 12 including a keyboard and/or other input device 13, a control panel 14, and a display screen 16. The console 12 is connected via a connection 18 to a separate computer system 20, and the computer system 20 enables an operator to control the generation and display of images on the display screen 16. The computer system 20 includes a number of modules that communicate with each other through a backplane 20a, including an image processor module 22, a CPU module 24, and a memory module 26, the memory module 26 being a frame buffer for storing image data sets as is well known in the art. The computer system 20 is connected to a hard disk 28 and a magnetic disk 30, stores image data and programs, and is connected to a separate control system 32 through a high speed serial connection 34.
The control system 32 includes a set of modules interconnected by a backplane 32a, including a CPU module 36, and a pulse generator module 38 connected to the console 12 by a serial link 40. The control system 32 receives commands from the operator via the serial connection 40 that require a scan sequence to be performed. The pulse generator module 38 runs the system components to perform the specified scan sequence and outputs data, such as: timing, strength, shape of the rf pulse of the rf transmission, timing of the rf reception and length of the data acquisition window. The pulse generator module 38 is connected to a series of gradient amplifier systems 42 for controlling the duration and shape of the gradient pulses generated during the (index) scan. The pulse generator module 38 is capable of receiving patient information from a physiological acquisition controller 44, which physiological acquisition controller 44 acquires signals via a number of different sensors connected to the patient, such as acquiring electrocardiogram signals via electrodes mounted on the patient. The pulse generator module 38 is ultimately connected to a scan room interface circuit 46, and the scan room interface circuit 46 receives signals generated by sensors associated with the medical condition and the magnetic resonance imaging system. Through the scan room interface circuit 46, the patient positioning system 48 receives instructions to move the patient to a desired location for scanning.
The gradient waveforms produced by the pulse generator module 38 are applied to a gradient amplifier system 42 having Gx, Gy, Gz, each of which excites a corresponding one of the gradient coils in the gradient coil set 50 to produce magnetic field gradients used in generating corresponding spatially encoded signals. The gradient coil assembly 50 is part of a magnet assembly 52, the magnet assembly 52 further including a polarizing magnet 54 and a body radio frequency coil 56. Pulses generated by a transceiver module 58 in the control system 32 are amplified by a radio frequency amplifier 60 and coupled to the radio frequency coil 56 through a transmit/receive switch 62. Signals from the excited nuclei in the patient are sensed by the radio frequency coil 56 and transmitted through the transmit/receive switch 62 to the preamplifier 64, where the amplified magnetic resonance signals are demodulated, filtered, and digitized by the receiver portion of the transceiver module 58. The transmit/receive switch 62 may be controlled by signals from the pulse generator module 38 to electrically connect the RF amplifier 60 and the RF coil 56 in the transmit mode and to electrically connect the preamplifier 64 and the RF coil 56 in the receive mode. The transmit/receive switch 62 enables a separate radio frequency coil (e.g., a surface coil) to be used in both transmit and receive modes.
The magnetic resonance signals collected by the radio frequency coil 56 are digitized by the transceiver module 58 and then transmitted to the memory module 66 in the control system 32. The scan ends when the memory module 66 acquires a set of raw k-space data. The raw k-space data is rearranged into separate k-space data sets corresponding to each image to be reconstructed, each k-space data set is input to the array processor 68 for image reconstruction and combined with the magnetic resonance signals to form a set of image data, which is transmitted to the computer system 20 via the serial connection 34 and stored in a storage device, such as the hard disk 28. In response to commands issued by the console 12, the image data may be stored for a long period of time, for example, on the magnetic disk 30, or further processed by the image processor 22 and transmitted to the console 12 and displayed on the display screen 16.
Fig. 2 shows a method according to the invention for positioning a patient in a magnetic resonance system, which comprises:
s201, inputting personal information of a patient to acquire a human body model matched with the patient.
In this step, the patient's personal information is entered into the computer system 20 via the keyboard and/or other input device 13 and displayed on the display screen 16. The personal information of the patient includes height, weight, age, scanning position of the patient, the direction of the patient in the scanning cavity of the medical device, and the like. With the input personal information of the patient, a human body model data suitable for the patient is matched in the computer system 20. Wherein, the direction of the patient in the scanning cavity of the medical device comprises that the head or the feet of the patient face forwards, lie prone or supine, lie on the left side or the right side.
Mannequins are measurement procedures in medical devices. The human body model which can meet the use requirement mainly comprises the following parameters: torso length, head circumference, and parameters that describe the pose.
S202, position information of a scanned part of the patient is calculated.
S203, determining the position information of the target position.
In this step, the target position may be input via the keyboard and/or other input device 13 and displayed on the display screen 16. In this embodiment, the target position is the isocenter of the magnetic resonance apparatus. In another embodiment, the target position may be a position that has been set by the system immediately after shipment.
S204, the control system controls the scanning bed to move so as to move the scanning part to the target position.
In this step, the target position is the isocenter of the magnetic resonance apparatus. The scanning bed can acquire the current positions in three directions, and simultaneously, the part to be scanned is moved to the isocenter through the scanning bed according to the calculated distance from the scanning part to the isocenter. In practical application, the technical scheme provided by the invention has three specific implementation modes.

In this step, the position of the scanning bed moved into the scanning chamber of the medical device may be entered into the computer system 20 via the keyboard and/or other input device 13. The scanning bed is automatically moved to the entered position while moving the patient. In other embodiments, the patient may be manually moved into the scanning lumen of the medical device.
And S303, acquiring a scout image of the patient through scout image scanning, and determining the position information of the patient through the scout image.

For some specific parts, a method of image processing can be used to obtain a landmark region of the part to be scanned, and the position information of the landmark region can be used as the position information of the scanned part. For example, when scanning the head, the distance from the site to be scanned to the target site is calculated with reference to the position of the corpus callosum or the brain fissure. When the spine is scanned, the position of cerebrospinal fluid is regarded as the spine; when the thoracic and abdominal region is scanned, the positions of the lung and diaphragm are regarded as the positions of the thoracic and abdominal region.
