摘要： A system and methods for the efficient segmentation of globally optimal surfaces representing object boundaries in volumetric datasets is provided. An optical surface detection system and methods are provided that are capable of simultaneously detecting multiple interacting surfaces in which the optimality is controlled by the cost functions designed for individual surfaces and by several geometric constraints defining the surface smoothness and interrelations. The graph search applications use objective functions that incorporate non-uniform cost terms such as “on-surface” costs as well as “in-region” costs.

摘要： A method for routine monitoring and quality assurance of field asymmetry of high energy circular radiation beam producing equipment. The quality assurance process of field symmetry for devices such as stereotactic radiosurgery (SRS) systems is simplified by directly measuring the integration of the half-beam profile. The method of the invention provides that the field symmetry is obtained by positioning the tip of an ion chamber, with a collecting length approximately half the diameter of the beam, at the central axis of the beam, and rotating the ion chamber at varying angular positions, acquiring and comparing readings at desired angular positions. Each pair of readings from positions 180 degrees opposed from each other, are plugged into the equation, Asymmetry=2(R1−R2)/(R1+R2) to compute asymmetry.

摘要： A VLSI wavelet transform (WT) architecture suitable for use in a discrete wavelet transform (DWT) or a discrete wavelet packet transform (DWPT). The WT architecture has a multiplier; an accumulator; at least two address generators that has a first address generator and a second address generator; a control unit; a memory of result that stores computation results; and a memory of table, which pre-stores all possible weights, each of which weights is a product of some specified filter coefficients for performing a DWT/DWPT with parameters of decomposition level, length of data segment, and filter length. The first address generator and the control unit receive data input, the control unit exports control signals to multiplier, accumulator, second address generator, and memory of table. The memory of the table also receives outputs from the first address generator and the second address generator to select the desired weights of the filter coefficients, which are sent to the multiplier to obtain a product with the data input. The product is sent to the accumulator to add into a corresponding sum, and the memory of result receives the corresponding sum and an address output of the second address generator to address the received corresponding sum, in which when all of the data input in the DWT/DWPT are completely inputted, each the corresponding sum is an end result of the DWT/DWPT.

摘要： A method for fiducial-less real-time motion tracking of abdominal tumors based on the correlation between the patient's breathing pattern and the diaphragm/lung border during treatment delivery. This invention utilizes an edge detection technique to delineate the diaphragm/lung border on radiographic images in order to calculate or determine tumor locations in the abdomen. The position of the diaphragm/lung border is synchronized with the breathing pattern obtained from continuous optical monitoring of a patient's respiratory cycle. The real-time optical breathing pattern obtained from monitoring is used to determine or calculate the position of the diaphragm/lung border during treatment delivery. The position of the diaphragm/lung border is then used to determine the tumor location in real-time. The target tumor coordinates generated through this process are used by the treatment delivery system to adjust the radiation beam geometry of the treatment delivery system to follow the tumor in real-time and accurately deliver radiation dose.
