摘要： Provided herein are devices and methods for mounting variously configured medical imaging probes to a tracker assembly for imaging applications. In one aspect, a tracker assembly provides multiple degrees of freedom for positioning a probe relative to a patient and/or maintaining a probe in a desired location for imaging purposes. The tracker generates location information that may be utilized as frame of reference information for acquired images. In another aspect a holding device allows for interfacing/holding differently configured probes in a common orientation to a predetermined frame of reference.

摘要： Provided herein are devices and methods for mounting variously configured medical imaging probes for imaging applications. In one aspect, a holding device allows for interfacing/holding most conventional ultrasound probes such that the probes may be attached to a positioning device using a common interface. As ultrasound probes come in various sizes and lengths, the device may adjust to different lengths, widths and shapes of different probes. Hence, the device may work in a substantially universal manner while securely holding probes with little wobble or other problems.

摘要： This application presents a new system and method for image acquisition of internal human tissue, including but not limited to the prostate, as well as a system and method for the guidance and positioning of medical devices relative to the internal tissue. In the presented systems and methods, ultrasound scanned data (e.g., 2-D B-mode images) are acquired freehand absent a mechanical armature that constrains an ultrasound acquisition probe in a known spatial framework. To allow for reconstruction of the scanned data into a 3-D image, multiple tracker sensors that provide position/location information are used with a freehand acquisition probe (e.g., handheld ultrasound probe). The position of such tracker sensors can be calculated when disposed in an electromagnetic field.

摘要： A spatially varying PSF may be applied in a camera simulator by multiplying a fixed weight map by its impact region. Next, Fast Fourier Transform (FFT) both IWk and Ak, multiply the FFT results element by element and do an inverse FFT (IFFT) to bring the results back to spatial domain. The output image is exactly the same as the outcome of direct approach with the same interpolation method for spatially varying PSF. However, the operation now will be significantly faster in some embodiments.
摘要翻译：空间变化的PSF可以通过将固定权重图乘以其影响区域而应用在照相机模拟器中。接下来，在IWk和Ak两者之间进行快速傅立叶变换（FFT），逐个乘以FFT结果，并进行逆FFT（IFFT），使结果回到空间域。输出图像与用于空间变化PSF的相同插值方法的直接逼近的结果完全相同。然而，在一些实施例中，现在的操作将显着更快。
