Abstract: An improved probe guide and probe guide system for use in conjunction with a medical imaging device is disclosed. The medical imaging device may be any type of imaging device that generates a cross-sectional image of a portion of a patient's body in a single image plane, such as, ultrasound, CT, or MRI imaging devices. The probe guide allows maintaining the movement of the probe within the image plane and accurate placement of a probe, such as a biopsy needle, by allowing a range of angular translation of the probe. The probe guide system enables extrapolation of the penetration path of the probe held by the probe guide and superimpose it on to the cross-sectional image allowing the medical personnel to view the penetration path of the probe within the patient in advance.

Abstract: A corn plant is evaluated by a six-step method. The first step is to select a population of mature corn plants to be evaluated. A limited number of representative plants from the population are then selected. The representative plants are then harvested by cutting them near the ground. The plants are then ground into a homogeneous mixture. A sample of the homogeneous mixture is then analyzed in a near infrared spectrometer. The analysis is then compared with an existing correlation between near infrared analyses and wet-test chemistry tested nutritional compositional characteristics to predict the compositional characteristics of the corn plant population.
