The invention relates to automatically adjusting an acquisition protocol for dynamic medical imaging, such as dynamic CT, MRI or PET imaging. The protocols are adjusted based on anatomic and dynamic models (10, 12, 14) which are individualized or fitted to each patient based on a scout scan (6, 8). The adjustment can compensate for changes in the patient due to patient motion (e.g. breathing or heartbeat) or flow of contrast or tracing agent during the sequence. This ensures that changes in the reconstructed images are indicative of pathological changes in the patient and not caused by patient motion or changes in scanning parameters or timing. The dynamic model can be a motion model (12) used to predict the motion of anatomic/physiologic features, typically organs, during scanning, or a haemodynamic model (14) used to predict flow of the contrast agent allowing for precise timing of the scanning sequence.

Nuclear imaging systems, non-transitory computer readable media and methods for adaptive imaging are presented. Particularly, the present method includes acquiring preliminary projection data by scanning each of one or more views of a subject for a determined preliminary scan interval. Further, a region of interest of the subject is identified. The preliminary projection data is then used to perform a constrained optimization of a rapidly computable image quality metric for determining an acquisition protocol that improves the image quality metric at the identified region of interest. Particularly, the determined acquisition protocol is used to acquire target projection data corresponding to at least the identified region of interest. Further, an image of at least the identified region of interest is reconstructed using the target projection data, the preliminary projection data, or a combination thereof.

A data processing system is disclosed which includes a first processor having an m-byte data width, an n-byte data bus, where n is less than m, and a second processor electrically coupled to the bus which performs bus transactions utilizing n-byte packets of data. An adaptor is electrically coupled between the first processor and the bus which converts n-byte packets of data input from the bus to m-byte packets of data, and converts m-byte packets of data input from the first processor to n-byte packets of data, thereby enabling the first processor to transmit data to and receive data from the bus utilizing m-byte packets of data. In a second aspect of the present invention, a method and system are provided for arbitrating between two bus masters having disparate bus acquisition protocols. In response to a second bus master asserting a bus request when a first bus master controls the bus, control of the bus is removed from the first bus master. Thereafter, in response to a signal transmitted from an arbitration control unit to the first bus master instructing the first bus master to terminate its bus transactions, control of the bus is granted to the second bus master. In response to the second bus master terminating its bus request, control of the bus is granted to the first bus master and a signal is transmitted from the arbitration control unit to the first bus master acknowledging the grant of control.

In a wireless communication system having sometimes mobile subscriber units and a plurality of fixed network devices located at cell sites, a multimode acquisition protocol is provided at each subscriber unit which first senses whether the subscriber unit is static or mobile from the nature and quality of the communication links with nearby network devices and then enables an acquisition protocol suited to either static mode or mobile mode. In a specific embodiment, the protocol initiates procedures to change acquisition mode from static to mobile upon failure of the subscriber unit to sense three consecutive scheduled polling packets sent by a linked network device or upon loss of communication with any locally-known network device or upon failure to transmit 25 consecutive data packets. In such case, the procedure is initiated to determine whether it is appropriate to switch to a mobile mode for purposes of acquisition.

Techniques for reducing the scan time required for the acquisition of two or more magnetic resonance imaging images of a subject having differing contrasts. In one arrangement, a combo acquisition protocol of N sets of parameters is selected prior to imaging. In order to image a subject, a first set of parameter values is selected from the protocol, a first RF pulse and at least one gradient field are used to excite the subject, a refocusing RF pulse and at least one gradient field is applied to the subject, a phase encoding gradient field is applied to the subject, and then a measurement gradient field is applied to the subject simultaneously while an induced signal is measured. The process is repeated to obtain N measurements, which are then processed into two or more reconstructed images of differing contrast, and where some of the measurements are used during the reconstruction of two or more of the images.

Techniques are disclosed for allocation of resources under the control of resource managers and the choice and coordination of resource acquisition protocols to communicate with these resource managers. The resource managers may be distributed and heterogeneous. For example, a technique for use by a service provider for allocating one or more resources from multiple resources associated with multiple resource managers based on at least one service agreement offer from a service client comprises the following steps/operations. At least one service agreement offer is obtained. A resource allocation is automatically determined based on the obtained service agreement offer. The automated step/operation of determining the resource allocation comprises: (i) coordinating selection of a resource acquisition protocol from among multiple resource acquisition protocols for use in communicating with the multiple resource managers to acquire one or more resources associated therewith; and (ii) evaluating a performance associated with one or more of the multiple resource acquisition protocols.
