An apparatus and method for subsequent optimization of radiosurgery and radiotherapy is provided. The invention includes administering a metalloporphyrin to the patient, and then creating a 3-dimensional mapping of tissue through use of PET or SPECT. Malignant and pre-malignant tissue has an affinity for the metalloporphyrin. During treatment, real-time images are also provided which are compared to the previous 3-dimensional mapping. Creation of the real-time images is also achieved through PET or SPECT wherein a metalloporphyrin is administered to the patient. Total administration of radiation is calculated by summing radiation from the inetalloporphyrins and from the radiosurgery / radiotherapy. The amount of radiation delivered by the metalloporphyrins and by the radiosurgery / radiotherapy are adjustable based on a patient's response to the dual delivery.

A device for picture-providing diagnosis of tissue is selectively operated in a picture-providing white light diagnosis mode and a picture providing auto-fluorescence mode. A color camera having red, green, and blue sensors provides a monitor which picture signals. A light source emits fluorescence excitation light and additionally emits so much red light that the red light remitted by the tissue dominates the red fluorescence light in the picture providing auto-fluorescence mode. The signal from the red sensor of the camera is damped so that normal time appears green and pre-malignant and early malignant tissue appears red.

A microscope array with staggered rows of magnifying imaging systems is used to scan a biological tissue sample in a single linear pass to produce an image and corresponding optical-density data. A conventional computerized algorithm is used to identify, isolate and produce segmented images of nuclei contained in the image. The OD values corresponding to nuclear chromatin are used to identify numerical patterns known to have statistical significance in relation to the health condition of the biological tissue. These patterns are analyzed to detect pre-neoplastic changes in histologically normal-appearing tissue that suggest a risk for the development of a pre-malignant and a potentially malignant lesion. This information is then converted to a visually perceptible form incorporated into the image of the tissue sample and is displayed for qualitative analysis by a pathologist.
