Problems solved by technology

However, in the case of thermal imaging, such methods do not provide accurate registration since the thermal imaging data is derived from the surface of the imaged body part rather than the internal tissue

[0090] Contour model with superimposed thermal data

[0091] A model of the surface contour of the female breast is generated and used to map thermal data onto it.

[0092] Materials and methods

[0093] A projector (Mitsubishi Electronics Model XD206U) and a camera (Pixelink Model PL-B741F) were used to acquire three-dimensional profile data. Thermal images were acquired using a thermal camera (FLIR model PHOTON OEM).

[0094] In order to acquire thermal data superimposed on the surface profile, thermal cameras and visible light cameras must be co-calibrated using a single calibration target. The system needs to be calibrated only once, after which the position of each device is fixed. The calibration of (video and thermal) cameras is achieved by relating the pixels present in the images captured by these cameras to known spatial reference points. Similarly, projectors are calibrated by associating projected pixels with such spatial reference points. To reconstruct the...

Abstract

A method of obtaining imaging data from a tissue region is provided. The method is effected by associating imaging data with a surface contour of the tissue region and utilizing a model of contour changes in the tissue region to transform the data to reflect changes in the surface contour.

Description

technical field [0001] The present invention relates to systems and methods for enabling registration of medical imaging data, and more particularly to systems and methods for enabling registration of tissue imaging data for improved diagnostic resolution. Background technique [0002] Medical imaging is routinely used to image the human body or parts thereof for clinical or research purposes. [0003] For more than 70 years, medical imaging has relied almost exclusively on traditional film / screen X-ray imaging. However, over the past 40 years, medical imaging has undergone major technological growth that has resulted in the development and commercialization of new imaging techniques. Such techniques include X-ray computed tomography, magnetic resonance imaging, digital subtraction angiography, ultrasound, thermography, and nuclear emission imaging (e.g., PET, SPECT, etc.), which are now routinely used to detect and diagnose disease . [0004] The availability of this dia...
