Trace the object boundaries using the "Boundary Editor" or one of the segmentation functions.

Both MRI and CT scans make cross-sectional images (slices) of pretty much any area of the body using a sophisticated computer system. The major difference is that an MRI uses a large magnet and radio waves to produce images while a CT scanner uses x-rays. Therefore, with the MRI studies, there is no exposure to x-rays.

Computed Tomography (CT) uses x-rays to create a cross-sectional image of the body part being examined. Magnetic Resonance Imaging (MRI) uses a high field strength magnet and radio waves to generate a cross-sectional image.

MRI scan is excellent at showing soft tissue such as spinal cord, nerve roots and herniated discs. A CT scan shows bone detail and some soft tissue. When looking for herniated discs or tumors, an MRI image will usually reveal much more detail.

MRI stands for Magnetic Resonance Imaging and does not utilize radiation. Instead, a strong magnetic field and radio waves are combined to create high-quality images of soft tissue which cannot be detected by an X-ray.

CT and MRI differ in two basic ways.CT uses x-rays to detect and record the radiation absorbed by different tissues, and sends the data to a computer to transform into images. MRI does not use x-rays. Instead, MRI employs a powerful magnetic field to monitor the nuclei of hydrogen atoms in water, the most abundant element in the body.

CT stands for Computerized Tomography, which refers to the way this exam is performed. In actuality, a CT scan is an x-ray procedure which is enhanced by a computer. This results in a three-dimensional view (referred to as a "slice") of a particular part of the body. During a routine x-ray, dense tissues can block other areas.

CT imaging itself is painless. The patient is required to remain motionless during the examination (which is difficult for some people), but the actual scan causes no bodily sensation.

Yes, the volume of a 3D surface model can be calculated easily using the Process/Calculate Volume command within the surface model window. This command computes both volume and surface area. To adjust the scale and unit for volume calculation, the scaling parameters should be entered using the Edit/Calibration command before rendering is done. If you have your 3D model saved in a format supported by 3D-DOCTOR, such as DXF, STL, PLY, raw triangle, etc.

Numerous studies have shown that even for people who have large body tattoos there is little to no potential for irritation resulting from an MRI. In the rare instance where discomfort resulted, it was localized and very temporary. Most people have more metal in their fillings than they would ever have in tattoo work.

After your test, call the office to schedule a follow-up appointment. Dr. Stanley will explain and discuss your results at this time.

Because an MRI scan uses a magnet and does not use X-ray or particle beams, an MRI scan produces no ionizing radiation.

MRI is more sensitive to subtle changes in soft tissues, particularly the brain and spinal cord. It is the primary imaging method for evaluation of joints, especially the knee, ankle, shoulder, and wrist.

CT and MRI provide different kinds of information. Your doctor determines which is the most appropriate test for you, and sometimes both are necessary. While both scanners are similar in appearance, CT scanners make images is by using x-rays to plot the difference in electron density of adjacent tissues, and MR scanners, as described above, make images based on differences in the density and behaviour of hydrogen protons.

Our preferred provider for mammograms, CTs, and MRIs is Bexar Imaging Centers. There are two locations one is located across from North Star Mall and other is off 7622 Louis Pasteur across from the Methodist Children's Emergency Room.

This is can be done quite easily. Resliced volume images make 3D measurement of certain objects more accurate. It works as if you are allowed to rotate your CT or MRI scanner around the patient for the perfect imaging position, but a lot easier. Open your image and then select the Image/Reslice/Reslice Volume command. Enter the 3D angle you want to use and click "Start" to create the resliced image in a few seconds.

By referencing the system (the MicroScribe itself, and/or the location the orientation of the system to registration points), the size of object or scanning volume is technically unlimited (although, scanning objects larger than an automobile may be impractical).
