Ablation planning with lesion coverage feedback
A tumor targeting ablation planning device and method include providing a predetermined ablation profile and a segmented tumor to be treated in an ablation procedure. A contour of the segmented tumor is generated and the predetermined ablation profile is overlapped with a part of the segmented tumor to form an overlapping region, which is identified. Further, a predetermined safety factor is applied to at least a part of the at least one segmented tumor in the overlapping region to generate a modified overlapping region. Parts of the overlapping region that are arranged outside the modified overlapping region are determined as overlapping portions. A display is configured to: display the contour of the segmented tumor, display the predetermined ablation profile overlapped with the at least part of the segmented tumor in the overlapping region, and display the overlapping portions in relation with the contour and the ablation profile as virtual planning ablation result.

Devices and methods for creating holes in the articular process of the vertebra are provided. One embodiment of the invention comprises a drill head comprising a frame, punch arm with punch tip and opposing plate. Methods of using the resulting holes to anchor or stabilize facet joint prosthesis, and also altering the spacing and motion at the facet joints of the vertebral column, are provided.
ELECTRONIC PHENOTYPING TECHNIQUE FOR DIAGNOSING CHRONIC KIDNEY DISEASE
An example method of diagnosing chronic kidney disease (CKD) includes obtaining an electronic medical record for a patient having medical data. The medical data includes an indication if the patient had been previously diagnosed with CKD, an indication if the patient had previously undergone a kidney transplant, an indication if the patient had previously undergone a renal dialysis procedure, an indication if the patient had previously been diagnosed with another type of kidney disease, one or more glomerular filtration rate (GFR) measurements associated with the patient, an indication if the patient has type 2 diabetes, and/or an indication if the patient has hypertension. The method also includes automatically determining that the patient has CKD or does not have CKD based on the medical data in the electronic record.
Distinguishing diseased tissue from healthy tissue based on tissue component fractions using magnetic resonance fingerprinting (MRF)
Example embodiments associated with characterizing a sample using NMR fingerprinting are described. One example NMR apparatus includes an NMR logic that repetitively and variably samples a (k, t, E) space associated with an object to acquire a set of NMR signals that are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The NMR apparatus may also include a signal logic that produces an NMR signal evolution from the NMR signals and a characterization logic that characterizes a tissue in the object as a result of comparing acquired signals to reference signals. Example embodiments facilitate distinguishing diseased tissue from healthy tissue based on tissue component fractions identified using the NMR fingerprinting.

Magnetic resonance fingerprinting (MRF) with efficient acquisition schemes
Example apparatus and methods improve magnetic resonance fingerprinting (MRF) by performing MRF with optimized spatial encoding, parallel imaging, and utilization of field inhomogeneities. Multi-echo radial trajectories and spiral trajectories may acquire data according to sampling schemes based on models of charge distribution on a sphere. Non-uniform sampling schemes may account for differences in detector coil performance. Field inhomogeneities provide spatial information that enhances the spatial separation of an MRF signal and facilitates unaliasing pixels. The field inhomogeneity may be manipulated. An MRF pulse sequence may include frequency selective RF pulses that are determined by the field inhomogeneities. Inhomogeneities combined with selective RF pulses result in higher acquisition efficiency.

Magnetic resonance fingerprinting with steady state precession (MRF-FISP)
Example embodiments associated with NMR fingerprinting are described. One example NMR apparatus includes an NMR logic that repetitively and variably samples a (k, t, E) space associated with an object to acquire a set of NMR signals that are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. Sampling is performed in response to a fast imaging with steady state free precession (MRF-FISP) pulse sequence having an unbalanced gradient that dephases transverse magnetization. The NMR apparatus may also include a signal logic that produces an NMR signal evolution from the NMR signals, and a characterization logic that characterizes a resonant species in the object as a result of comparing acquired signals to reference signals. The unbalanced gradient in the MRF-FISP pulse sequence reduces sensitivity to B0 in homogeneity.
